The multi-performance drill bit with unique SMART STEP technology (from dia. 2.5 mm) for manually drilled high-precision circular holes in almost all materials, such as stainless steel (e.g. V2A, V4A), heat-resistant steels and titanium. Also suitable for general applications in conventional steel up to 1200 N/mm² strength as well as in cast iron, non-ferrous metals, hardwood and softwood.

Newly designed step drill tip geometry (from dia. 2.5 mm)

Significantly quicker than conventional twist drill bits

Significantly less effort compared to drilling with a conventional extra-long twist drill bit

Precise circular holes without centre-punching

Extremely convenient drilling

Saves pre-drilling, precise spot drilling without running off centre

Tilted drilling possible

Simple reboring or enlarging of an existing drill hole

Perfect for drilling out rivets

Ideal for drilling round materials or pipes with high requirements on centring, precision and service life, such as in railing construction

First twist drill bit that enables the precise handheld drilling of up to dia. 20 mm holes without predrilling

Optimised step drill tip geometry

Shank reduced to dia. 12.7 mm from > 13.0 mm nominal bore diameter 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 transfer of force

Protection of the drill chuck from damage

Little effort required to open and close the drill chuck

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

Notice

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