Specification

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 stepped drill bit tip geometry (from dia. 2.5 mm)

Significantly faster than conventional twist drill bits

Significantly less effort required when drilling compared to conventional twist drill bits

Precise, circular holes without centre-punching

Extremely comfortable drilling

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

Angled drilling possible

Simple drilling or enlarging of an existing drill hole

Perfect for drilling out rivets

Ideal for drilling in round material or pipes with stringent requirements for centring, precision and service life, e.g. in railing construction

The first twist drill bit to enable precise drilling up to dia. 20 mm without pre-drilling in hand-held tools

Optimised stepped drill bit tip geometry

Shank reduced to dia. 12.7 mm from > 13.0 mm drill bit diameter for use in all standard 3-jaw drill chucks

3-flat shank (from dia. 4 mm)

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

Optimal power transmission

Protects the drill chuck from damage

Minimal effort required to loosen and tighten the drill chuck

Product packaging made from 100 % PCR (recycled plastic from household waste) and 100 % recyclable

Notice

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

Application

Application area

Perfect for drilling round pipes (e.g. in railing construction), for drilling out stud bolts, rivet holes, for drilling sheet metal and thin-walled profile materials

Ideal for high-precision, comfortable and fast drilling in solid materials

Ideal for large bore diameters
