DIN 338, with 3 flat surfaces, short series, ground, with split point, point angle 118°.

The step size per diameter is variable for ideal force distribution and therefore this Step-Point drill ensures controlled and easy drilling. Ideal for sheet steel (≤2mm) and profiles, it also effortlessly drills round, burr-free holes in wood and plastic, regardless of the thickness. Allows drilling at an angle and does not slip thanks to the 3-chamfered shank.
