Drilling beyond standard jobber length increases sensitivity to thrust forces, chip evacuation, and thermal stability. The Inovatools 752 and 753 coolant-through drills are designed to control those variables in production drilling of steels, stainless steels, and cast iron.

Both series use a two-flute carbide geometry with internal coolant delivery and a 140° notched point. The design intent is stable entry, controlled chip formation, and consistent hole geometry as drilling depth increases.

Chip Control and Hole Quality
Hole quality is directly influenced by how chips are formed, broken, and evacuated from the cutting zone. When chips are removed efficiently and heat is controlled at the cutting edges, the drill maintains size, straightness, and surface finish more consistently.

The combination of internal coolant delivery, notched point geometry, and controlled flute design in the 752 and 753 series addresses these mechanisms directly, resulting in stable drilling behavior across a range of ferrous materials.

Application Fit
The Inovatools 752 and 753 series are designed for CNC drilling applications requiring 3×D and 5×D depths with internal coolant. They are suited for shops machining steels, stainless steels, and cast iron where hole geometry, chip evacuation, and process stability must remain consistent over production runs.

Diameter selection, application matching, and process recommendations should be reviewed based on material, machine capability, and coolant delivery.

Everede Tool Company boring bars are engineered to maintain stiffness, braze integrity, and dimensional stability under cutting load. Each construction element is intended to preserve cross-sectional strength and minimize deflection at the cutting edge.

Shank Configuration and Flats
Series A–D bars are manufactured without flats as standard. Eliminating flats preserves full shank diameter, increasing the second moment of area and improving resistance to bending. ANSI-style bars may include one or two flats by diameter when required for set-screw retention.

Flat width is limited to what is necessary for clamping force while maintaining structural integrity. Clamp-sleeve mounting maintains full circumferential support of the shank and provides the highest achievable rigidity.

Result – Increased stiffness and improved resistance to deflection under radial cutting forces.

Internal Coolant Hole Geometry
Coolant holes are drilled to a diameter-specific size that is smaller than many competing designs. Reducing internal bore diameter increases remaining wall thickness and improves bar rigidity.

The coolant passage delivers flow directly to the cutting zone while preserving strength through the neutral axis. This supports longer diameter-to-length ratios without increasing vibration risk.

Result – Higher structural stiffness with controlled coolant delivery at extended overhangs.

20° Cone Angle at the Insert Pocket
The insert pocket incorporates a 20° cone interface between the carbide head and steel shank. This geometry increases effective brazed surface area and distributes load over a larger bonded interface.

The increased brazed area improves load transfer and reduces localized stress concentrations during cutting and interrupted engagement.

Result – Improved braze joint strength and reduced risk of braze failure.

Insert Projection Length
The distance from the bar face to the cutting edge is minimized. Shortening this unsupported length reduces the bending moment applied to the bar during cutting.

Lower bending moment improves stability and reduces vibration amplitude at the insert.

Result – Increased cutting stability and improved dimensional consistency.

Combined Structural Effect
The combined effect of full-diameter shanks, reduced internal bore size, increased braze surface area, and minimized insert projection produces a boring bar optimized for rigidity. These construction elements support stable performance at longer overhangs and higher cutting loads across a wide range of boring operations.

When your machining operation demands absolute accuracy and dependable grip at high RPMs, not just any drill chuck will do. That’s where the Llambrich HEXA Series comes in—engineered for CNC professionals who won’t settle for second-best.

Built for High-Performance Machining
The HEXA Series is part of Llambrich’s advanced CKS line, and it’s purpose-built for CNC applications like drilling, milling, reaming, and tapping. These chucks are designed with integral shanks, which means the body and taper are machined from a single piece of steel. That eliminates potential misalignment between chuck and shank—delivering tighter tolerances and improved rigidity.

And when you’re pushing the limits of your spindle, precision matters. The HEXA chucks are dynamically balanced up to 25,000 RPM (G6.3)—making them ideal for high-speed machining environments where vibration control is critical for tool life and surface finish.

Repeatable Accuracy, Every Time
With a runout of less than 0.05 mm, the HEXA Series gives you the kind of consistent, repeatable performance you need to minimize tool wear and maintain part quality over long production runs. That level of concentricity isn't just a spec—it’s a competitive edge when working with tight-tolerance components.

Drill capacities range from 0.5 mm up to 16 mm (0.02"–5/8"), covering everything from micro drills to standard taps. Whether you're running a small part on a Swiss machine or a multi-tool job on a vertical machining center, the HEXA has you covered.

Lock It In With ConfidenceThe standout feature?
Llambrich’s Hexa-Lock system. This design integrates a hex-key mechanism that allows you to apply significantly more torque than with a hand-tightened chuck—without risking slippage. It’s a smart combination of convenience and control: the simplicity of a keyless chuck, with the confidence of a locked-in hold.

Why Llambrich?
With over six decades of manufacturing experience and full in-house production at their Barcelona facility, Llambrich has built a global reputation for ultra-precise, long-life chucks. The HEXA Series reflects their ongoing innovation—delivering performance you can trust, shift after shift.

Looking for a drill chuck that keeps up with your spindle speeds—and your expectations? 
Ask Browne & Co. about integrating the Llambrich HEXA Series into your next high-speed setup. We’re proud to represent Llambrich across Ohio, Indiana, Kentucky, and Western Pennsylvania, and we’re ready to help you spec the right solution for your shop.

Tecnologie FRB builds face drivers around a single engineering objective – transmit torque through the face of the part while maintaining controlled axial thrust and predictable concentricity. That lets you machine the entire OD in one setup with the part located on its true center. You’re driving from the face, holding center, and finishing the OD in one shot. The result is consistent torque transfer, repeatable part location, and fewer setup headaches across turning, grinding, and gear cutting.

Two Generations of Engineering Experience
FRB is a second-generation, family-run Italian manufacturer that has focused exclusively on face-driving systems for decades. That narrow focus shows up in the details. The face driver is treated as a dedicated workholding system rather than a variation of a chuck or clamp.

Pin geometry, axial thrust control, and centering methods are engineered around how parts behave under load in CNC turning, grinding, and gear cutting. The design intent is stability at the cut, not theoretical performance.

How an FRB Face Driver Works
Torque is transmitted through hardened driving pins that engage the face of the workpiece while a center point establishes axial location. The part is driven from the face and located from center, leaving the entire outside diameter clear for machining.

With no jaws contacting the OD, the full external surface can be machined in a single setup. The driving pins float radially, allowing them to accommodate minor face variation while maintaining consistent torque transmission once axial load is applied.

Axial Thrust Control
Axial thrust is generated either by internal spring packs or by a hydraulic cylinder, depending on the face driver configuration. In both cases, thrust is applied at a defined and repeatable level that presses the workpiece into the driving pins.

Controlled axial load prevents overloading thin sections while still providing sufficient force to transmit torque during heavier cuts. Load consistency is maintained from part to part, reducing variation caused by changes in part length or face condition.

Spring-Loaded Face Drivers
FRB spring-loaded face drivers generate axial thrust through internal spring packs acting through the tailstock. This mechanically simple system provides consistent load and repeatability for soft turning, hobbing, and general production work.

Because the part is referenced from the center rather than the OD, runout is controlled at the functional datum. Typical center-based runout remains within about 0.001", depending on size and configuration. The spring system maintains consistent contact when small variations exist in the part face, keeping the drive stable

Hydraulic Face Drivers
FRB hydraulic face drivers apply axial thrust using an integrated hydraulic cylinder rather than relying solely on tailstock force. This allows higher thrust levels and tighter control, supporting heavier turning and grinding operations.

Axial load is applied through the spindle, improving rigidity and reducing sensitivity to tailstock condition. Hydraulic models are used where tighter runout is required and where long production runs need consistent stability under changing cutting loads.

Centering, Locking, and Accuracy Control
FRB face drivers are centered on the machine spindle using radial set screws or dedicated centering holes, depending on flange style. Once centered, the unit is locked to eliminate radial and axial movement during operation. This aligns the face driver to the spindle axis rather than relying on chuck jaw accuracy. Concentricity and roundness are governed by the center reference, independent of OD condition or gripping surface quality.

Driving Pins and Center Points
Driving pins are available in multiple sizes and orientations, with right-hand and left-hand options to match spindle rotation. A small amount of rotation under load helps the pins seat evenly and keep the drive consistent. Center points come in fixed, spring-loaded, and slotted versions. Slotted centers make room for lubrication or shallow center holes without giving up axial accuracy.

Flange and Mounting Options
FRB face drivers are available with integral flanges, Morse taper shanks, and bolt-on flanges with centering holes. This makes it easier to use the same face driver across different machines while keeping it running true and solid.

Typical Applications
Face drivers are commonly used for shaft production, transmission components, gear blanks, and precision ground parts where full OD access and center-based accuracy are required. Eliminating jaw distortion and secondary setups improves process stability and cycle-to-cycle consistency.

FRB face drivers are built to control axial load, stay on center, and drive the part without slipping. Spring-loaded and hydraulic versions let the face driver match the cut instead of fighting it. When the part stays centered and solid, the process stays predictable and the machine gets used the way it should.

For sizing help, configuration selection, and application support, contact Browne Sales to discuss the appropriate FRB face driver for your machines and parts.

In today's labor competitive machining environment, productivity is still all about spindle uptime. When your spindle isn’t turning, your shop is losing money. That downtime—whether it’s during tool setup, part changeover, or job prep—translates directly into delayed output, higher operating costs, and lower profit margins.

HAIMER, a global leader in precision tool holding, presetting and balancing, is offering WinTool software to U.S. manufacturers. Together, HAIMER and WinTool deliver a fully integrated tool and data management system that’s designed to help shops minimize downtime and keep spindles running.

The Five Keys to Unlocking Spindle Uptime
To increase spindle utilization and streamline machining operations, manufacturers need to focus on:

1. Optimizing production schedules
2. Writing efficient NC programs to reduce cycle time
3. Minimizing setup time for fixtures and tools
4. Eliminating production prep delays
5. Speeding up tool and part changeovers

HAIMER’s lineup of tool presetters, balancing machines, and toolholders—now backed by WinTool’s powerful CNC data management—makes it possible to address all five of these areas with a single solution.

Custom-Fit for Your Shop’s Needs

HAIMER USA, now the exclusive distributor of WinTool in the U.S., offers the tools to meet those unique needs.

By combining HAIMER Tool Management 4.0 with WinTool’s centralized data system, shops can bring together CNC programming, CAM software, presetters, and storage solutions into one cohesive workflow.

Eliminating the Workflow Bottleneck
One of the biggest obstacles manufacturers face is fragmented information. R&D, production, programming, and quality often work with separate software systems and databases—ERP, CAM, machine controls, presetters—all of which rarely communicate. The result? Bottlenecks that delay ROI and choke productivity.

HAIMER’s integrated solution tackles this issue head-on. With a complete portfolio of toolholding, balancing, and presetting equipment, combined with WinTool’s Production Resource and Tool (PRT) Management, shops gain the ability to bridge departmental silos and streamline the entire machining process.

Results That Speak for Themselves
At HAIMER’s own manufacturing facility in Germany, the team uses WinTool every day to support the production of up to 4,000 tool holders. After implementing WinTool internally—well before offering it commercially—they saw immediate results. In just four months, WinTool was fully operational. Within the first year, the facility reduced cutting tool costs by over $300,000 through better visibility into tool inventory, locations, and life cycles.
​
Those savings continue to grow as WinTool’s PRT system enables deeper integration and smarter resource allocation across departments.

Centralized Data for Smarter Manufacturing

No matter what kind of part or material you are moving, your sling is the critical connection between your load and the crane. You can’t afford failure. That’s why more and more people are turning to Tuffy® Synthetic Web Slings—engineered solutions built for demanding applications where safety, reliability, and long service life are essential.

Tuffy slings go beyond basic lifting; they’re designed with industry-leading features that reduce wear, improve load control, and withstand some of the most demanding environments in manufacturing, construction, and field service.

Polyester vs. Nylon—Which Should You Choose?
Both materials get the job done, but each has its own strengths depending on your specific environment:

• Stretch under Load: Nylon stretches about 6% under rated capacity. Polyester stretches less, offering a bit more load stability.
• ​Chemical Exposure: Polyester stands up better to acids, while nylon withstands stronger alkalis.
• Sunlight Resistance: Both degrade over time in direct sunlight, though Tuffy applies treatments to improve durability. Still, storing slings out of the sun is always a smart move.
• Heat Range: Neither material should be used in temperatures above 194°F (90°C) or below -40°F (-40°C).
• Moisture & Oil: Both are highly resistant to water, seawater, oil, grease, and many common chemicals—perfect for messy shop or field conditions.

Want a nylon sling? Tuffy can make that on request, but polyester is their go-to for most applications because of its consistent performance in industrial settings.

Soft Enough for Sensitive Loads—Strong Enough for Structural Steel
When you’re lifting delicate or highly polished loads, you don’t want to risk scratches, dents, or surface damage. That’s where Tuffy’s synthetic web slings come in. Designed with protection in mind, these polyester web slings offer a soft but durable solution for lifting fragile loads safely and securely.

One of the key advantages of synthetic web slings like Tuffy is their ability to securely grip the load without causing surface damage. Unlike wire rope or chain slings, which can scratch, dent, or deform sensitive materials, Tuffy web slings distribute the load evenly across a broad contact area. This makes them ideal for lifting painted components, precision-machined parts, delicate surfaces, or coated beams. The elasticity of the synthetic webbing also helps absorb shock loading and reduce peak stresses, which can be critical when dealing with variable lifting conditions or delicate cargo.

Visibility, Traceability, and Safety—Built In
Every Tuffy sling includes color-coded identification for easy capacity recognition. Whether you’re sorting slings on the shop floor or selecting gear at the job site, color-coding helps avoid misapplication. Each sling also comes with a permanently attached, heat-sealed tag that details its rated load capacities for vertical, choker, and basket configurations. These tags meet ASME B30.9 requirements and help ensure compliance with OSHA inspection and rigging safety standards. Having clear and durable identification on the sling improves traceability and supports proper usage by your rigging crew—reducing human error.

Custom-Built Options for Real-World Challenges
Tuffy offers a wide range of sling configurations, including endless slings, flat eye and eye, twist-eye, reverse eye, and wide-body basket slings, allowing you to match the tool to the task. Standard web widths range from 1 inch to 12 inches, with ply options from single to quadruple, depending on capacity and application. . Type 6 (RE) Reversed Eye Slings offer extra durability and are great for vertical, basket, or choker hitches. Type 7 (FE) Flat Eye Slings let you rig through tight spaces and remove the sling easily from beneath the load. 

Tuffy also manufactures custom sling solutions to meet job-specific lifting challenges, including special lengths, wear pads, edge guards, and hardware attachments. If you’re lifting loads with complex geometries or requiring specific rigging points, Tuffy can help engineer the right solution to get it done safely and efficiently.
Capacities range from 3,100 lbs up to 32,900 lbs vertical, with even greater strength in basket hitches. And if you’re not seeing exactly what you need—just ask. Custom is part of the game at Tuffy.

Optional Scuff Edge™ Webbing Protection
​For applications that push gear to the limit, Tuffyoffers slings made with Scuff Edge™ webbing—a specially woven outer layer that delivers better abrasion resistance.

Understanding the characteristics and applications of insert types allows you to make informed decisions that improve efficiency, productivity, and overall outcomes in your machining processes. This short guide aims to provide a comprehensive overview of insert types compatible with Everede boring bars and how their distinctive features contribute to profitable  machining.

Everede boring bars accept a selection of standard carbide inserts.  Understanding how and why certain style so inserts are sued for the different types of bars will help you improve tool life and finish.  Everede offers inserts in the following geometry:  CDCD, TDGB-3, TDGH-3, & TDGC, TPGB-3, TPGH-3, & TPGC-3 and WCGT (Trigon) Inserts.

As you already know, the ANSI and ISO insert designation systems provide a standardized way to describe the shape, angle, and other attributes of cutting inserts used in machining operations. The first letter of the insert code indicates the shape of the insert, while the second letter refers to the clearance angle.

Here's how CD, TD, TP, and WC (Trigon) style inserts compare based on these designations:​

In summary, the choice between CD, TD, TP, and WC style inserts depends largely on the specific requirements of the machining operation, including the bore size, material hardness, and the desired balance between cutting edge strength and clearance angle.

CD and TD inserts, with their 15-degree clearance angle, are more suited to applications requiring a high degree of clearance to avoid dragging in smaller diameters.

In contrast, WC inserts, with their 6 cutting edges and 7-degree clearance angle, offer enhanced cutting edge strength for heavier cuts in larger diameters, although they provide less clearance.

TP inserts strike a balance with an 11-degree clearance angle, offering a compromise between clearance and edge strength.

As a final note, please keep in mind that Everede boring bars also often have the insert seated in a pocket that may enhance the clearance angle. For more information please contact Browne & Co to set up a call to answer your questions.
