Stepped twist drill bit range HSS SMART STEP Deepcut 3 pieces

Precise circular holes

No tool changes and shorter machining times

• Eliminates predrilling with smaller twist drill bits, precise tap without the bit running-out of centre


• Saves extra deburring, as the next larger step diameter performs this function


• Combines numerous bore diameters in a single tool


• Very fast tap and faster drilling process due to four high-performance blades and SMART STEP technology

Flexible, “smart” use

• Now also suitable for 10 mm strong material thickness (compared to conventional step drill bits, which are limited to 4 mm material thickness on sheet metal)


• For use in cordless drills as well as on hand-held, pillar, and upright drills.


• Compared to using core drill bits with magnetic core drills, there are no problems with hard-to-reach places (e.g. on T-beams) or problems due to insufficient adhesive forces

Very comfortable drilling

• Drilling with less strain


• Completely smooth running without getting caught in the workpiece


• No sheet metal distortion


• Simple re-drilling or enlarging of an existing drill hole


• Reduced force exerted on the tool during the drilling process

AlCrN multi-layer wear protection coating

• Extremely high temperature resistance of up to 1050° C


• Very high coating hardness of 3000 HV


• Multilayer construction for optimum chip removal and improved cutting properties (prevents material wear)

3-face shank

Prevents turning in the drill chuck, ensures optimal power transmission and protects the drill chuck from damage

ORSY^® system compatible, compact and practical system cassette with useful details, such as stackability, optimised joint, and easy opening
