Milling cutters are sometimes a major shop expense, and you probably invest in the best tools for your shop. That’s why many shops today use carbide end mills. You can use them for many applications, and they stay sharp longer than high-speed steel cutters. However, it’s important to get the most from your carbide milling cutters, and these helpful tips can extend the life of your tools and make your shop a little more efficient.
For Universal Milling Consider Square End Cutters with Two Flutes
Double flute square end cutters work for many applications. If you have a lot of contouring or slotting needs, these tools are perfect for the jobs. The flutes are far apart, and this feature limits chip buildup, which is important for high-speed milling. Because the end is square, you get a perfect ninety-degree angle for slotting work, and there’s no need for finishing.
Use High Spiral Carbide End Mills for Soft Materials
High spiral or high wedge cutters are specially made for milling soft metals. This is especially important when milling aluminum because some alloys are sticky and don’t machine easily. You’ll enjoy fewer problems with issues like tool deflection, too. Due to their design, you receive fast chip ejection, so you have fewer chances for clogging the flutes while cutting. Their superior cutting ability lets you mill at lower speeds to save energy.
Know Your Styles
In some cases, three, four, or six flute carbide end mills are best for the job. For example, if you want the cutting power of multiple flutes but don’t want chip buildup problems, three flute cutters are a good choice. For greater accuracy and less tool deflection, choose four flute cutters for the job. Talk to your shop tool supplier about the best tools. They are there to help you make the right decisions.
