Drill bit set KWB 206515

Drill bit set KWB 206515 contains two precision-ground, DIN 338 standard twist drills with right-hand cut, type N, in natural (self) colour. The bits have a 135° tip angle and are cross-ground to DIN 1412 C for improved centering. Manufactured for industrial use, they are cylindrical-shanked and suitable for drilling in steel and alloyed steel, cast steel, die castings, sintered steel, non-ferrous metals and hard plastics.

Advantages

The KWB 206515 set provides precision-ground flutes and a cross-ground tip for reliable self-centering and accurate starts. The 135° tip angle reduces walking on hard surfaces and improves hole quality. Cylindrical shanks ensure compatibility with standard chucks, and the DIN 338 manufacturing standard indicates consistent dimensions and industrial quality.

Suitable for

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

How to use

Secure the selected drill bit in a compatible chuck and clamp the workpiece firmly. Use appropriate cutting speed and feed for the material being drilled, apply steady moderate pressure, and clear chips regularly. For metals, use cutting fluid to reduce heat and extend tool life. Begin drilling at low speed to ensure the cross-ground tip centers correctly, then increase speed as appropriate for the material.

Usage recommendations

For best results, match drill speed and lubricant to the specific material: lower speeds for harder steels, moderate speeds for non-ferrous metals and plastics. Inspect bits before use for damage and replace worn drills to maintain hole accuracy and safety.
