Boor KWB 206575 7,5mm 1 stuk

The KWB 206575 drill bit is a precision-ground, right-hand twist drill with a 7.5 mm diameter, manufactured to DIN 338. It has a self-colour finish, a 135° tip angle and is cross-ground to DIN 1412 C for improved self-centering and cutting action. Supplied as a single piece in blister packaging, this cylindrical industrial-quality drill is intended for drilling steel, alloyed steel, cast steel, die castings, sintered steel, non-ferrous metals and hard plastics.

Advantages

This drill bit offers precision-ground flutes and a cross-ground tip for consistent centering and chip removal. The 135° tip angle reduces walking on hard materials and increases contact stability. Produced to DIN 338 standards, the bit provides reliable industrial quality and compatibility with common drill chucks. The single-piece design and blister packaging simplify handling and storage.

How to use

Mount the 7.5 mm KWB drill bit securely in the drill chuck and ensure the workpiece is clamped. Use appropriate cutting speed and feed for the material being drilled; reduce speed for harder steels and increase for non‑ferrous metals and plastics. Apply steady pressure and allow the drill to cut without forcing. Clear chips frequently, and use coolant or cutting fluid when drilling steel or alloyed materials to prolong tool life and improve hole quality.

Recommendations

For best results, start with a small pilot hole when drilling large or deep holes, maintain correct speeds for the work material, and use cutting fluid on ferrous materials. Inspect the bit for wear before use and replace when the cutting edges are blunt or damaged.
