- For blind holes, please note the extended drill tip (see dimension l3)!
- The steps of the innovative point geometry drill gradually to achieve the required diameter. To achieve this, the chip is broken into small individual chips by several main cutting edges, thus ensuring optimal chip removal. The result is highly precise, circular drilling.
- The use of several cutting edges at the same time enables very fast, comfortable working and a long service life.
- Ideal for use in cordless drills as well as on hand-held, box column and pillar drills
- For use in steel up to 1,000 N/mm², cast iron, aluminium, copper, brass, bronze, hard and soft wood, plastic (e.g. acrylic glass, HPL, screen printing plates) and composite materials (e.g. plastic profiles with steel core)
- High drill hole quality and significantly longer service life compared to conventional twist wood drill bits.
- Perfect for rivet holes, drilling out stud bolts, drilling sheet metal and thin-walled profile materials (e.g. aluminium/window profiles) and for drilling on round and sloping surfaces, such as pipes.
- Ideal for high-precision, comfortable and fast working in solid materials (e.g. in steel with strength of up to 1,000 N/mm², aluminium and plastics).
- Ideal for large drill hole diameters
