Specification

The latest generation of Performance stepped drill bits for longer service lives, significantly faster drilling with smooth running and greatly reduced formation of burrs when processing thin workpieces made from conventional steel with a strength of up to 900 N/mm², aluminium, cast iron, brass, bronze, wood and plastics.

4 times longer service life

Compared to comparable bare stepped drill bits

Improved centring and up to 100% faster spot drilling

Exclusive Speed grinding

Acceleration of the overall drilling process

Significantly lower feed forces

Optimised cutting geometry

Completely smooth running without getting caught in the workpiece

No distortion of sheet metal

Improved roundness of the hole

Greatly reduced formation of burrs on the edges

Up to 80% reduction in force exerted on the tool during the drilling process

Optimised cutting profile with smoother transitions between the individual stages

3-face shank

No twisting in the drill chuck: faster, more comfortable working

Optimum transmission of forces

Protection of the drill chuck from damage

Little effort required to open and close the drill chuck

Application

Application area

Centring, drilling, core drilling and deburring of sheet metal, pipes and profiles in a single step, when using both hand drills and stationary equipment.

The latest generation of Performance stepped drill bits are ideal for processing sheet metal, panels, profiles and pipes made from conventional unalloyed steel with a strength of up to 900 N/mm², aluminium, cast iron, brass, bronze, wood and plastics with a thickness of up to 4.0 mm. Alloyed steels with strengths of up to 900 N/mm² can be processed up to a thickness of 2.0 mm.

Instructions

Ensure that there is sufficient cooling/lubrication

Make sure that the feed is even

Observe the speed table

Do not push during core drilling – the stepped drill bit will automatically retract into the sheet metal
