Twist drill bit KWB 206602

The KWB 206602 twist drill bit is a precision-ground, right-hand cut drill designed for accurate drilling in a wide range of materials. Manufactured to DIN 338 with a 135° tip angle and cross-ground geometry to DIN 1412 C, this single-piece cylindrical bit provides self-centering performance and industrial-quality durability for professional and DIY use.

Advantages

Precision-ground geometry and adherence to DIN standards ensure consistent hole quality and reliable centering. The 135° tip angle and cross-ground finish reduce walking and improve entry accuracy. The solid, single-piece construction offers durability and resistance to breakage when used within recommended parameters.

Suitable for

• Steel and alloyed steel
• Cast steel and die castings
• Sintered steel
• Non-ferrous metals (e.g., aluminum, brass)
• Hard plastics

How to use

Secure the workpiece and select the appropriate drill speed for the material being machined. Use suitable cutting fluid when drilling ferrous materials to extend tool life and improve chip evacuation. Start drilling with light pressure to ensure self-centering, then apply steady feed until the hole is completed. Retract periodically for deep holes to clear chips and reduce heat buildup.

Usage recommendations

For best results, match drill speed and feed to the material type, use cutting fluid on steels, and avoid excessive side loads. Inspect the drill for wear or damage before use and replace when tip geometry is degraded.
