Explore the role of end mill components in machining various materials with our guide on selecting the right features based on ISO 513 classifications, enhancing machining efficiency and tool life.  The components of an end mill play a crucial role in determining its performance and suitability for machining different materials. The best way to understand the importance of different features of an end mill is start with the material you are cutting. Just like a butter knife is not good for cutting steak, selecting features for an end mill is very dependent upon the material you're cutting. Let's start with some background information. The ISO 513 is a standard that classifies materials based on their machinability and provides guidelines for cutting speeds, feeds, and tool selection. ISO 513 provides a classification system for the machinability of materials, organizing them into categories based on the characteristics which influence their behavior during machining processes. The main categories include:
Now, let's dig into the details. Below you'll find the key components of an end mill and how they relate to machining different ISO 513 material types:
End Mill Anatomy Overview The anatomy of an end mill refers to its various components and features, each of which plays a critical role in its cutting performance. End mills are rotary cutting tools used in milling operations to remove material from a workpiece.
Here's a breakdown of the key parts of an end mill:

Looking for an end mill with unsurpassed performance in high-efficiency milling of Titanium? The new Fullerton 3116 TiMill end mill may be just what you need. Titanium is half the weight of steel and twice the strength of aluminum: It's a high strength, light weight material with excellent fatigue performance, super durable in high stress environments and corrosion resistant.  As a result of titanium's material properties it's making it become evermore popular in the aerospace, defense, shipbuilding, medical adn dental industries. It's also what makes it considered a "more difficult to machine" material. Let's dig into that a bit more. Generally, titanium grades 1 through 4 are considered commercially pure titanium with varying requirements on ultimate tensile strength while Grade 5 is what is most often seen in the machining industry. It's often alloyed with 6% aluminum and 4% vanadium. This is what is commonly known as 6Al4V or Ti 6-4. Also quite common is 4Al4V or Ti 4-4. Why difficult? Well, first it has low Young’s modulus meaning that is more elastic than other materails: It's "gummy" which often causes spring back and chatter during machining and can readily generate long stringy chips if you don't have the correct edge prep. On top that, it's also prone to work hardening and galling super easily. You've got to keep the cutter in-the-cut: Insert cutters just aren't as good as solid endmills at doing this. Next, titanium does not have good thermal conduction properties like aluminum. Instead of heat being evacuated in the chips or transferred to the base material, heat tends to be transferred to the cutting tool which reduces it's tool life. Heat kills. Tool life declines. The right coating helps. The final icing on the cake is that titanium is prone to work hardening. During uniaxial loading, the initial rate of hardening is higher in compression so if you come back for another pass you need to get under the work hardened layer, that is, leave enough material for a finish pass to get under the layer or your tool life will suffer and your part finishes will decline with it. Ideally, finish to size in the final pass if you can. The trick to machining titanium has always been to keep consistent coolant flow to evacuate the chips and maintain a consistent chip load. Again, rough to your finish size. Don't let it work harden. That's what we've learned about titanium over the past couple of decades. There has been a ton of research on titanium's properties and that research has led to further refinement of the cutting tool geometry at Fullerton. The design of Fullerton's 3116 TiMill is based upon over a decade of aerospace testing and development and addresses many of the machining issues that Titanium presents. It's a 6-flute tool built with a 38°helix. The increased number of flutes allows for the tools to remain "in the cut" longer and more consistently. It doesn't induce as much heat as a lower number of flutes tends to do. instead, it's consistent. The 38°helix evacuates the chip at a more optimum angle than a 35°, 37.5° or 40° helix that predecessors made by competitors have tried.

In 1918, Carl A. Bergstrom opened the Weldon Tool Co. in Cleveland. Working from his shop atop the Blackstone Building, he developed a new kind of endmill with a 30° helical flute. The thing cut like crazy. Bergstrom quickly realized that his toolholder lacked the gripping power to hang onto his cutting-edge endmill, as the thing kept spinning right out of the holder. He took the end mill and ground a flat spot on its side of it's shank, giving the toolholder’s clamping screw a place to bite into. Bergstrom had invented the Weldon flat shank.
 Fullerton Tool Standard Weldon Flat A Weldon flat is a flat section on a tool shank. When placed in a Toolholder the flat on the shank is held in place by set screws within the body of the holder. Using this flat, a set screw securely holds the tool and prevents the tool from rotating when machining. Weldon flat tools are predominately used when milling but can be used in other applications. When rough machining and removing large amounts of material, Weldon flat holders can be beneficial. Particularly in the Aerospace sector when machining parts such as expensive wing spars, tool pullout can occur which can be very costly and damaging. When machining materials such as Titanium, optimal machining parameters produce high torque forces on the cutter, Titanium requires an aggressive depth of cut at relatively slow spindle speeds and Weldon Flat holders are ideal for these types of applications. However, Weldon Flat tools do have their disadvantages. Weldon-style endmill holders by their design push the cutter off centre which creates runout and can drastically reduce tool life. Tool Balancing (or imbalance) can also be a problem. Fullerton Tool offers both Standard Weldon Flat and Advanced Performance Weldon FlatAt Fullerton Tool they have 2 types of Weldon Flats available - the Standard Weldon Flat and the Advanced Performance Weldon Flat. The Standard Flat (WF) and the Advanced Performance Weldon Flat (AF) are essentially the same, but the length of the Weldon Flat to the cutting tool is different. The Advanced Performance Weldon Flat (AF) is measured from the flute washout to the flat. This guarantees that the flute or flute washout will not be inside of the holder. If the flute or flute washout is inside the tool holder, the chips can pack into the holder and cause the tool to break.
 Fullerton Tool Advanced Weldon Flat Guest Blog by Mark Donze at Fullerton Tool  Have you ever wondered if you should purchase high-performance end mills or general-purpose end mills and what the benefit of purchasing one over the other is? If so, we have put together a list of factors to consider to help you make the right decision for next time. General Purpose End MillsFirst, let's discuss general purpose end mills. General Purpose (GP) End Mills are standard single, 2, 3, or 4 flute geometry end mills made for use in a wide variety of materials. Benefits of General Purpose End Mills:
High-Performance End MillsNext, High-Performance (HP) End Mills contain specialized geometries for a specific material being cut. Benefits of High-Performance End Mills:
With this information in mind, if you are a company that does small runs in a wide variety of materials you may prefer GP end mills. Whereas, if you are making high-volume parts where cycle-time and up-time are king, you may prefer an HP end mill for your use. Remember, there are no hard lines drawn. Each application is different and preference is ultimately up to you, the end-user.
If you aren't sure, you can contact your Fullerton authorized distributor to help make this decision. We will work with you to get the end results you desire with a wide variety of both GP and HP end mills available. We even have some tooling where we apply HP coatings to GP tools to help you get the most out of your cutting tool investments. We have a huge selection of inventory items and of course, if you need a special tailored tool to your specific needs, we have engineering and application knowledge to get the most out of your cutting tool budget. We also have resources on our website to help you navigate which tool is the best for your needs.
