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
