If your Carbide Drill includes a self-centering point, there is typically no need to use a spotting drill. This feeds and speeds table was compiled using premium grade double-sided 1-ounce (37micron) copperclad with a 0.059" (1.5mm) thick FR-4 core. The Speeds and Feeds Calculator may be employed for calculations of estimated speeds and feeds (RPM and IPM) values on the basis of the parameters you have currently set based on Steel < 180 HB. Of course getting broken carbide drills or solid carbide taps out of a hole is going to be painful. Steel < 180 HB. HSS drills can only go to 2-3x diameters deep then they must peck. of material that needs to be removed when re-grinding. Because it is so brittle, it should be reserved for production drilling using a high quality tool holder and drilling machine. If youre having problems with the occasional wad of chips hanging from the drill at the end of a cycle, try programming a quick reverse spindle run.
