Three Flutes Coating Aluminum End Mills / Tungsten Carbide End Mill Cutter
KTC Tungsten Carbide End Mills for Aluminum
When you’re picking out your end mills, make sure you check on the following qualities.
Flutes
Fluting affects how quickly a bit cuts while you’re running it in your machines. The more flutes, the quicker the cut, which makes it tempting for some people to try and go with the highest number possible.
That’s a rookie mistake.
Aluminum is a soft material, which tends to heat quickly and have large chips separate while the end mill is in motion. This means that you want to lower the number and cut a bit slower to ensure a smooth and accurate cut and avoid “tearing” which will leave you with a rough cut.
If you really overdo it, you can also clog the bit.
This means that the ideal aluminum bit is going to come with two or three flutes. Once you get any past that you’re running the risk of messing with your cuts, which isn’t good for anyone.
Material
The material that your bit is made of is primarily of importance to those who use their machining tools a lot.
High speed steel is the “inferior” of the two materials but a good quality end mill will still last for a long time in a hobbyist’s shop. This steel is designed to withstand the high RPMs of your machines, after all.
Carbide, on the other hand, will stay sharp practically forever and is ideal for professionals. Of course, a single carbide piece might cost as much as an entire set of high-speed steel bits.
Coating
There’s also the matter of coating, which is particularly important for high-speed steel tools. Many of the new commercial coatings can reduce friction by a ton, keeping the bit cooler while it runs and decreasing the friction which can cause clogs in a soft material like aluminum.
