Broca helicoidal Cimco 208630

The Cimco 208630 twist drill bit is designed for use with rotary hammers and offers reliable drilling performance across a range of common materials. Constructed as a single-piece right-hand rotation bit, it provides stable cutting action and is intended for repeated use in professional and hobby applications. The geometry and build are tuned to deliver precise holes while maintaining durability under medium to heavy use.

Advantages

This twist drill bit combines a single-piece construction with a right-hand rotation profile to reduce vibration and improve concentricity during drilling. Its durable material composition and manufacturing tolerances contribute to consistent hole quality and extended operational life. The design supports stable chip removal and efficient penetration, helping to maintain drilling speed and reduce bit wear.

Key specifications

How to use

Select the appropriate drill speed and hammer setting on your rotary hammer according to the material being drilled. Secure the bit in the hammer chuck, ensure the workpiece is stable, and mark the drilling point. Start drilling at low speed to establish a guide hole, then apply steady pressure and engage the hammering action for efficient penetration. Periodically withdraw the bit to remove debris and prevent clogging. After completion, allow the bit to cool before storage.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves, ear protection) and follow the rotary hammer manufacturer's guidance. Choose a drill diameter and hammer settings that match the material and required hole size to maximize bit life and achieve accurate results.
