Drill Bit KWB 206570, 7 mm diameter, right-hand cut, type N. The bit is precision ground, made in natural (self) colour and has a 135° tip angle with cross-ground geometry according to DIN 1412 C for reliable self-centering. It is a cylindrical shank, industrial-quality drill intended for drilling steel, alloyed steel, cast steel, die castings, sintered steel, non-ferrous metals and hard plastics. Supplied as a single piece in blister packaging.

Advantages

The KWB 206570 7 mm drill offers a 135° tip angle and cross-ground cutting edges for improved centring and reduced walking at the start of drilling. Precision ground flutes and industrial-grade material provide consistent hole quality and dimensional accuracy. The cylindrical shank fits standard chucks and the right-hand cut suits conventional drilling machines.

How to use

Mount the 7 mm KWB 206570 drill bit securely in a compatible drill chuck. Use appropriate cutting speed and feed for the workpiece material, apply cutting fluid when drilling steels and alloyed metals to improve tool life and chip evacuation, and ensure the workpiece is clamped firmly. Start drilling at low speed to allow the self-centering tip to locate the hole before increasing to recommended speeds for the material.

Recommendations

Use cutting fluid when machining steels and cast materials; reduce speed and use gentle feed for sintered materials and hard plastics to avoid overheating and burring. Inspect the bit for wear before use and replace when cutting edges become dull to maintain hole quality.
