HSS SMART STEP Deepcut stepped twist drill bit

Highly precise circular holes

No tool changes and shorter machining times

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


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


• Combines numerous bore diameters in one tool


• Very fast spot drilling and faster drilling process thanks to four high-performance cutting edges and SMART STEP technology

Flexible, “smart” use

• For the first time, also suitable for up to 10 mm thick workpieces (in comparison, conventional stepped drill bits are limited to sheet thicknesses of 4 mm)


• Specially designed version that combines all core hole dimensions (Ø 3.3–10.2 mm) for through hole threads M4–M12 to 1.5xD in a single tool


• 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 in hard-to-reach places (e.g. on T-beams) or difficulties due to insufficient adhesive force

Extremely convenient drilling

• Low-effort drilling


• Completely smooth running without getting caught in the workpiece


• No distortion of sheet metal


• Easy to bore or enlarge an existing drill hole


• Less force exerted on the tool during drilling

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