The KWB 706325 centering drill bit is a DIN 7483 G centre bit designed for precise wood drilling. Made of tempered special steel, it has a welded drilling head with a serrated precision blade and optimally sharpened, hardened cutting edges to deliver clean, tear-free holes even at larger diameters. The bit features a centering tip, low sliding friction and reduced heat development, and is suitable for use in rotary drills and hammer drills with 10 mm or 13 mm chucks. It is intended for hard and soft wood, veneered wood, coated chipboard, MDF and core boards. The bit is supplied as a single piece in blister packaging and has a bright finish with black grooves.

Advantages

The special tempered steel construction and welded head provide increased durability and a longer service life. Serrated precision blades and hardened cutting edges ensure extremely precise and easy cuts with clean borehole edges. Low friction and reduced heat generation enable faster drilling and improved efficiency; the manufacturer states up to 45% faster drilling and corresponding energy savings compared with customary centre bits. The bit fits common 10/13 mm chucks and is versatile for a range of wood materials.

How to use

Secure the centering drill bit in a compatible 10 mm or 13 mm chuck and tighten according to the drill manufacturer’s instructions. Mark the drilling point, position the centering tip, and start drilling at low speed to establish the center. Increase speed as required while applying steady, even pressure; avoid excessive force to reduce heat and wear. Clear chips periodically to maintain cutting efficiency and allow the bit to cool if prolonged drilling is necessary.
