Drill Bit KWB 206590 9mm Right Hand Rotation 1pc

The KWB 206590 drill bit is a 9 mm, right-hand rotation tool manufactured to DIN 338 standards. It is a type N, precision-ground, cylindrical shank drill with a 135° tip angle and cross-ground geometry to DIN 1412 C, offering self-centering performance in a natural steel finish. The bit is industrial quality and intended for drilling in steel and alloyed steel, cast steel, die castings, sintered steel, non-ferrous metals and hard plastics.

Advantages

The drill bit provides precise, repeatable drilling thanks to its precision ground body and cross-ground tip. Self-centering geometry improves hole start and reduces walking. Manufactured to DIN 338 and DIN 1412 C tolerances, it ensures consistency in professional and hobbyist applications. The cylindrical shank fits standard chucks and the universal material suitability allows use across a wide range of workpieces.

Suitable for

• Drilling holes in steel and alloyed steel
• Working with cast steel and die castings
• Processing sintered steel components
• Drilling non-ferrous metals (e.g., aluminium, brass)
• Creating holes in hard plastics

How to use

Secure the drill bit in a compatible chuck and tighten firmly. Select an appropriate rotational speed and feed rate for the workpiece material—lower speeds for hard materials, higher speeds for softer non-ferrous metals and plastics. Start drilling with light pressure to ensure the self-centering tip locates the hole, then apply steady, even feed. Withdraw occasionally to clear chips when drilling deep holes and use suitable cutting fluid when working with steels to extend tool life.

Usage recommendations

For best results, use cutting fluid when drilling ferrous materials, maintain correct spindle speeds for the 9 mm diameter, and replace the bit if cutting performance declines or if the tip is damaged. Store the drill bit in its blister to prevent damage and corrosion.
