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
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
ORSY®-system compatible compact and practical system cassette with useful details, such as stackability, optimised joint and easy opening
For blind holes, please observe the extended drill tip!
Datasheets(X)
- 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
