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 drilling without centre-punching
Extremely comfortable drilling
- Saves pre-drilling, precise tapping without running off centre
- Angled drilling possible
- Simple boring or enlarging of an existing drill hole
- Ideal 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-guided use
- Optimised stepped drill bit tip geometry
- From drill diameter > 13.0 mm, shank reduced to dia. 12.7 mm for use in all common 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
- Little effort required to loosen and tighten the drill chuck
Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze
For blind holes, please note the extended drill tip (see dimension l3)!
