HSS SMART STEP Deepcut stepped twist drill bit

Precise, circular holes

No tool changes and shorter machining times

• Eliminates pre-drilling with smaller twist drill bits, precise spot drilling without running off-centre


• Eliminates additional deburring, as the next largest step diameter performs this function


• Combines numerous drill hole diameters in a single tool


• Very fast spot drilling and accelerated drilling progress due to four high-performance cutting edges and SMART STEP technology

Flexible, smart use

• Now also suitable for thicker workpieces with a material thickness of up to 10 mm (compared to conventional stepped drill bits, which are limited to sheet metal up to 4 mm thick)


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


• For use in cordless screwdrivers and hand, box column and pillar drills.


• Unlike when using annular cutters with magnetic core drills, there are no issues in accessing hard-to-reach places (e.g. on T-beams) or due to low adhesive force

Extremely comfortable drilling

• Effortless drilling


• Completely smooth running without getting caught in the workpiece


• No warping of sheet metal


• Simple 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 1,050 °C


• Very high coating hardness of 3,000 HV


• Multi-layer structure for optimal chip removal and improved cutting properties (prevents material becoming welded)

3-flat shank

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