3 to 4 percent of tool diameter. 45-58 HRC. 2 to 3 percent of tool diameter. 60+ HRC. 1 to 2 percent of tool diameter. These feed rates assume a standard tool length. If an extended-length tool is needed because the hard-milled feature is also hard to reach, then a lighter feed rate is likely to be warranted.

3/64" End Mills | McMaster-Carr
For longer tool life and a better finish in general purpose milling applications, these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. …

Grinding balls, buy metal balls from Metinvest manufacturer
A ball mill is a drum-grinding unit where balls from solid materials (steel, iron, hard alloys, ceramics, etc) are used. Most common are ball mills, where when the drum rotates and the balls rub against the inner walls, the balls are lifted until the lifting angle becomes bigger than the angle of repose. Then the grinding media are again below.
