Apr 24, 2018 End mills for aluminum are often available in either 2 flute or 3 flute styles. With higher flute counts, it would become difficult to evacuate chips effectively at the high speeds at which you can run in aluminum. This is because aluminum alloys leave a large chip, and chip valleys become smaller with each additional flute on an end mill.
Standard Solid Carbide End Mill Speed and Feed Recommendations SPEEDS and FEEDS are suggested starting points and may be increased or decreased depending on actual material and machining conditions. In general, use lower speeds and feeds for hard and difficult-to-machine materials. Use higher speeds and feeds for easy-to-machine materials.
Extra Long End Mills For extra long end mills the SFM should be reduced by 25. Cutter Direction Cutter direction should be in a climb milling direction whenever possible. Con-ventional tool paths may be employed when the tool is in use on older manual equipment to minimize backlash or to remove scale to reach the softer parent material underneath.

Jan 27, 2016 Damn. 40 for a side cutting end mill. My mill maxes out at 4200 RPM and a 12 EM is something like 525 SFM at full speed. This barely makes a dent in the range for carbide in aluminum. When milling aluminum, based on my speeds available, should I keep buying coated carbide or find quality HSS mills

Jul 14, 2016 Hi, Today I was milling some 6061 aluminum with a 38 diam, 4 long two flute HSS end mill. I was plunging into the aluminum to a depth of 1.250 The first plunge was a partial cut basically off-center enlargement of a previously drilled hole.
May 02, 2019 This end mill is made of High-Speed Steel HSS which makes it super strong for any aggressive work. The set includes six different sizes inch, 532 inch, 4 inches, 516 inch, inch, and inch of end mills to fulfil your requirements. UDK end mill bits are mainly suitable for side milling, end milling, and finish machining.
When one end wears out, switch to the opposite end for two times the life of a standard carbide end mill. Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Use them to round sharp corners on the edge of your workpiece.
Types of End Mills End mills are commonly made of either high-speed steel HSS or Carbide. Dont let the name fool you into thinking that we must require HSS tools because our RPMs are so much faster. HSS tools are designed to work best with lower RPM milling machines and therefore are not a good choice for working with metals on a CNC router.
