    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

    Ball end mills, also known as ball nose end mills, are used for milling contoured surfaces, slotting and pocketing. A ball end mill is constructed of a round cutting edge and used in the machining of dies and molds. Roughing end mills, also known as hog mills, are used to quickly remove large amounts of material during heavier operations

When the endmill is perpendicular to the surface (cutting with the tip), I get a 27,500 rpm

    Jul 16, 2016 Jul 17, 2016 I am looking at getting an air spindle...which can get to 60,000 RPM. For a .031 endmill, even that will not get close. 60,000 RPM at .031 is 500 SFM. Assuming I keep my chipload in check (.0005 +/- = 61 ipm feed), will milling at 500 SFM cause issues with surface finish, etc.? Anyone have this sort of experience with small endmills in
