Drill Bit Bosch 2609255070 4.5 mm Diameter 80 mm Length

The Bosch 2609255070 drill bit is a 4.5 mm diameter, 80 mm length twist drill designed for precision drilling tasks. Intended for general-purpose use, this Bosch drill bit offers a consistent cutting profile and dimensional accuracy suitable for a range of common materials where a 4.5 mm hole is required. The 80 mm overall length provides extended reach for through-holes or medium-depth drilling operations.

Advantages

The drill bit combines a standard 4.5 mm diameter with an 80 mm length to balance accuracy and reach for typical workshop and on-site jobs. Manufactured by Bosch, it follows established production tolerances to deliver repeatable hole sizes and predictable performance. Its geometry supports efficient chip evacuation and stable cutting when used with appropriate speeds and clamping.

How to use

Select an appropriate drill speed and clamping method for the material to be drilled, and secure the workpiece to prevent movement. Install the Bosch 2609255070 drill bit into the drill chuck and tighten securely. Start drilling with steady, moderate pressure, withdrawing periodically to clear chips if drilling deeper holes. Use cutting fluid when drilling harder metals to reduce heat and extend tool life.

Recommendations

For best results, match drill speed and feed to the material, use proper clamping, and maintain a sharp cutting edge. Regularly inspect the bit for wear and replace when accuracy or cutting efficiency declines.
