Precise, circular drilling



No tool changes and shorter machining times


  • Saves pre-drilling with smaller twist drill bits, precise tapping without running off centre

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

  • Combines numerous drill hole diameters in a single tool

  • Very fast tapping 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.

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


Extremely comfortable drilling


  • Effortless drilling

  • Completely smooth running without getting caught in the workpiece

  • No warping of sheet metal

  • Simple boring 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 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
