WebUsing a ⅛” (.125”) diameter cutter instead of a ¼” (.25”) cutter the required RPM for aluminum example will be:-. 500SFM X 3.82 / .125 = 15,280rpm. This would be in the range of a typical cnc router. The next issue would be the feedrate. Using an RPM of 15,280 would give a feedrate of 122 in/min. WebThese taps are for use on most metal and plastic. They have a square shank that's compatible with tap wrenches and tap holders for drill presses and milling machines. Use uncoated high-speed steel taps for small-scale tapping jobs. Taper-chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece.
