Extremely unequal pitch (EU+)
- Up to 50 % longer service life
- Significantly more comfortable drilling with less vibration, even less effort required and perfect tool guidance (up to 60 % less torque)
- Up to 20 % lower energy consumption
- Up to 15 % faster drilling progress
Precise, circular drilling in a wide range of materials including wood, plastic and acrylic, without tearing or splintering
Extremely comfortable drilling

- Prevents the tool from running off centre even with particularly deep drilling
- Simple boring or enlarging of an existing drill hole
- No rattling or catching - even with thin-walled material
- Burr-free hole exit
Significantly faster and more energy-efficient drilling compared to conventional, extra-long HSS twist drill bits
3-flat shank (from dia. 4 mm)
- No spinning in the drill chuck: faster, more comfortable working

- For blind holes, please note the extended drill tip (see dimension l3)!
- The steps of the innovative point geometry gradually drill 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
- 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 quality of drill holes and significantly longer service life compared to conventional twist wood drill bits.
- Can be used universally on smooth as well as rounded and uneven surfaces
To achieve optimum drilling progress and avoid jamming, frequent "ventilation" of the drill bit is required for large drilling depths.
