The manually operated high-performance drill with unique SMART STEP technology (from dia. 2.5 mm) for high-precision circular drill holes in steel up to 1000 N/mm², aluminium, plastic, non-ferrous metals, hard and soft wood.

The original SMART STEP: First twist drill bit with stepped drill bit tip geometry (from dia. 2.5 mm)

Precise circular holes

Extremely convenient drilling

Saves pre-drilling, precise spot drilling without running off centre
Tilted drilling possible
Simple drilling or enlarging of an existing drill hole

Significantly quicker than conventional ground twist drill bits

Perfect for drilling out rivets and stud bolts

The first twist drill bit to enable precise hand-guided drilling up to dia. 20 mm without pre-drilling, and when used on a drill press even allows precise drilling up to dia. 26.5 mm without pre-drilling

From drill diameter > 13.0 mm, shank reduced to dia. 12.7 mm for use in all common 3-jaw drill chucks

3-face shank (from dia. 4 mm)

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

Sustainable product packaging made of 100% PCR (recycled plastic from household waste), 100% recyclable and Cradle to Cradle Certified^_® Bronze

Notice

For blind bores, please note the extended drill tip (see dimension l3)!

Application area

Perfect for rivet holes, drilling out stud bolts, for drilling sheet metal and thin-walled profile materials (e.g. aluminium/window profiles).

High quality of drill holes and significantly longer service life compared to conventional twist wood drill bits for drilling holes in wood.

Ideal for high-precision, comfortable and quick work in solid materials (e.g. in steel with strength of up to 1000 N/mm², aluminium and plastics).
