Drill bit set KWB 206520

The KWB 206520 drill bit set contains two precision ground, DIN 338 standard twist drills with right-hand cut and type N (cylindrical shank). The bits have a 135° tip angle and are cross-ground to DIN 1412 C for reliable self-centering. Finished in natural (self) colour, these industrial-quality drills are suitable for drilling in steel and alloyed steel, cast steel, die castings, sintered steel, non-ferrous metals and hard plastics. The set is supplied in a blister pack for convenient storage and handling.

Advantages

The drill bits are manufactured to DIN 338 with precision grinding for consistent diameter and straightness. A 135° tip and cross-ground geometry provide good centering and reduced walking on start-up. The cylindrical shank fits common chucks and the industrial-quality material delivers durability across a range of metals and hard plastics. The blister pack keeps the two bits organized and protected when not in use.

Suitable for

• Drilling steel and alloyed steel
• Drilling cast steel and die castings
• Working with sintered steel
• Drilling non-ferrous metals (e.g., aluminium, copper)
• Drilling hard plastics

How to use

Select a drill speed and coolant appropriate for the material being drilled (lower speeds for harder metals, higher for non-ferrous metals and plastics). Secure the cylindrical shank in a compatible chuck and ensure the workpiece is clamped. Position the 135° tip on the intended mark, start drilling with steady pressure and allow the bit to clear chips periodically. For metals, use cutting fluid to extend tool life; for plastics, reduce speed and avoid excessive heat to prevent melting.

Использование и рекомендации

Store the drill bits dry and protected in their blister. Inspect bits before use for wear or damage and replace when the tip is blunt or the geometry is compromised. Follow appropriate safety precautions: eye protection, secure workpiece, and correct feed/speed for the material.
