Solid Carbide Drills are not suitable for hand drills, and even drill presses are not ideal. 118 degree is common or wider 135 to 140 degrees are also available. You can look up the best point angle in references like the Machinerys Handbook, or you can use ourG-Wizard Calculatorto tell you the right point angle for any given material youve chosen: G-Wizard recommends either a split or notched point with a 135 degree anglefor 300 series stainless steel. It can withstand a lot more heat as well as being harder. Here we can compare standard versus parabolic flutes side by side: The big deal on the parabolics is the faster spiral. 217 speeds and feeds chart. Steel 180-280 HB. To ensure proper chip clearance, theFlute Length must be long enough so you have flutes 2x the diameter above the hole. MVS Long Type(DCx10, 15, 20, 25, 30, 35, 40) High efficiency drilling hole with 2000mm/min feed rate higher. (Scroll down for recommended feed rates by diameter) Steels.
