Carbide taps have a lot of advantages, especially when you’re cutting very abrasive materials. The absolute best choice for tapping glass-filled polycarbonates, space age alloys, nonferrous materials, cast iron, and a range of other exotic materials, their anti-friction qualities lead to a longer tool life.

S.T.I. (Screw Thread Insert) Taps are special taps for helical coil wire screw thread inserts, which provide positive means for protecting and strengthening tapped threads in any material.
​
Typically used on softer abrasive materials, these taps create more accurate thread forms than other standard taps. When you need to be precise, these carbide taps are the best choice.

North American Tool's  STI taps are correctly sized to produce an internal thread that accommodates a helical coil wire screw thread insert. The insert, in turn, will accept a screw thread of the nominal size and pitch at final assembly. Screw thread inserts provide stronger tapped threads (stronger assemblies) due to a more balanced distribution of loads throughout the length of thread engagement.

​
Thread forming taps (Tru-Flo taps) offer improved thread quality and strength due to the fluteless design, and therefore allows for greater fastener strength in the threaded product. This tap does not cut, so it is “chipless,” and therefore will not cause a chip problem.  This is why thread forming, over thread cutting, eliminates costly and time-consuming chip clean-up and disposal.

Thread forming taps are fluteless and include lubrication grooves. Not intended for general applications, they work by displacing the metal without removing it. Because of this, they are ideal for chip removal in blind holes.

​
​Tru-Flo Thread Forming Taps Features 

• Improved thread quality and strength due to fluteless design of tap; allows greater fastener strength in threaded product.
• Tapping speeds can be increased as much as double that of conventional cutting taps…more tapped holes per hour.
• Thread forming (over thread cutting) eliminates costly and time-consuming chip clean-up and disposal.
• Improved tap life, even in abrasive materials…no cutting edges to get dull.
• Lubrication grooves allow forced passage of air and lubricant when tapping.
• Simplifies tapping of problematic blind bottoming holes where adequate chip clearance is impossible with chip-producing cutting taps.

A cost-efficient solution, only the cutting portion of insert taps is made from carbide. Their HSS body is able to absorb vibration and account for their lack of rigidity.

If you’re considering testing the waters with carbide taps, insert taps are a great option. It's a very economical way to utilize the benefits of carbide with solid carbide cutting face inserts meticulously brazed to a H.S.S. tap body.

Carbide Insert Tap Features

• High speed steel body absorbs excessive shock and offers the rigidity necessary to minimize carbide breakage or chipping.
• Ideal for high production runs, offering the capability to achieve higher speeds and feeds, with fewer tool changes.
• High performance tapping allows greater efficiencies in part throughput.
• Can also be used in conjunction with surface treatments for enhanced performance.
• Carb-I-Sert® Taps are available in a wide range of sizes (inch and metric) in both straight and taper pipe threads.

Highly abrasive materials like cast iron, polymers, glass filled polycarbonates, and some cast aluminum are called “hard” materials for a reason. They’re hard to machine, hard on tool life and hard on production cycle times.

​How do you overcome the difficulties of making parts out of challenging raw stock? By using a tool that’s even tougher. Consider a change from steel taps to carbide taps.

​We offer carbide taps in UN and Metric sizes as well as straight and NPT/F Pipe and STI Standards. A wide range of styles and features are available, including straight flute, spiral flute, spiral point, and forming taps. For increased performance and life, we can customize tools with a full line of surface coatings such as TiN, TiCN, and TiALN.

Machining with carbide does come with some “do’s and don’t”. Hand­ tapping is generally not recommended. Rigid tapping and spot­-on alignment are critical to avoid breakage. Not to worry, however. Modern CNC equipment is ideally suited for carbide applications.

Here’s some additional tips. Coolant holes through the taps are an option for flushing chips out of the holes on the most difficult materials like some of the tougher stainless steels and space-­age alloys. Carbide STI (Screw Thread Insert) tapping of these materials has become commonplace in the aeronautical and aerospace industries.

Although initially more expensive than HSS taps, significant savings can be realized, especially in long-­run jobs. Higher cutting speeds, greater tool life, and reduced down­time from fewer tooling changes translate into reduced machining costs.

An alternative to costly larger sizes is our line of Carb­I­Sert® Taps. Solid carbide cutting surfaces are bonded onto a high-speed steel body to provide the best of both worlds; durability of carbide with the “forgiveness” of a steel body and shank.

So, don’t let difficult materials give you a “hard” time. Contact us anytime and put our carbide taps to work for you.

​Coming in August 2021: The Different Types of Carbide Taps and When to Use Them

Almost a year ago, Allen Benjamin, which has been a part of North American Tool,  was purchased by GWS Tool Group. GWS Tool Group is a US-based, vertically integrated manufacturer of highly engineered custom, standard, and modified standard cutting tools, primarily servicing the aerospace and defense, power generation, automotive and medical sectors. GWS Tool Group has acquired multiple businesses in the course of its growth which now serves as the respective manufacturing divisions for the Company.  

Just because there is a new owner, doesn't mean that the quality of an Allen Benjamin Tap has changed! 

If you’re in the market for high tensile strength carbide taps and metric taps, we can assure you that you’re in the right place. Not only is Allen Benjamin a leading supplier of the industry’s most durable, longest lasting carbide taps, we offer our customers the convenience of ordering online. In this day and age, we believe that quick access and top-notch customer services are critical.

In today’s post, we’re going to look at why it is beneficial to order your carbide taps from Allen Benjamin.

Quality

If you’ve been searching for a supplier that will meet your needs and rise to meet your challenges contact us today!

If you’re cutting extremely abrasive material, we’re confident that you’ve already investigated the benefits of carbide taps. Whether you’re tapping cast aluminum, nonferrous materials, polymers, cast iron, or any number of other materials, carbide taps offer better edge wear resistance and, more importantly, help to reduce downtime and increase profitability.

As an ISO 9001:2008 registered manufacturer, Allen Benjamin is absolutely committed to offering the best taps on the market. In today’s post, we’re going to look at a few of the benefits of using our carbide and high-performance taps.

Stronger
Ideal for very abrasive metals, carbide taps have a much higher tensile strength than standard taps. Because of this, they offer a longer tool life and work to reduce production costs.

Better performance
Due to their ability to increase tool life, carbide taps have a positive effect on your operation’s performance. Helping you to reduce maintenance and – by extension – downtime, they allow your staff to focus on more productive, more profitable tasks.

Cost-effective
While the initial cost may be higher than standard taps, carbide taps are far more cost-efficient in the long run. Their extended tool life results in fewer replacements which, of course, leads to less reorders and money saved over time.

At Allen Benjamin, we are steadfastly dedicated to our customers’ productivity. Always aiming to offer products that are capable of reducing maintenance, increasing uptime, and improving profitability, we strive to act as a convenient, responsive supplier of high-quality carbide taps. Whether you’re a small, local manufacturer in need of a handful of taps or a large, multi-national operation looking to place a large order, you can be confident that we can help. If you have any questions about our products, we encourage you to reach out to us today to discuss your needs!

Allen Benjamin’s carbide taps provide a substantial increase in performance and tool life over HSS – or high speed steel – taps. As a result, our customers experience longer tool life and, due to this, reduced production costs that help to contribute to higher profits and a more efficient line.
