Drill bit, Bosch 2608577531 — spiral design, 1 piece

Bosch HSS PointTeQ spiral drill bit for metal, diameter 7 mm with an overall length of 109 mm and a working length of 69 mm. The bit features an Inbus (6.35 mm) shank compatible with standard hex chucks and quick-change holders. Designed for metal drilling, it has a self-centering PointTeQ tip and a black-oxide coated flute for increased cutting speed and durability.

Advantages

The PointTeQ self-centering tip reduces walking at drill start for accurate hole positioning. Black oxide coating on the flute improves chip evacuation and corrosion resistance while supporting higher drilling speeds. The standard 6.35 mm Inbus shank ensures sturdy clamping and compatibility with many power tool chucks and adapters.

How to use

Secure the drill bit in a compatible 6.35 mm hex chuck or quick-change holder. Mark the drilling point and use steady, moderate feed pressure. For best results in metal, start drilling at low speed to engage the PointTeQ tip, then increase speed as the bit penetrates. Use appropriate cutting fluid when drilling thicker or harder metals to reduce heat and extend tool life.

Recommendations

The bit is intended for drilling metal; select suitable rotational speed and cutting lubricant based on the workpiece material. Avoid excessive side loads and overheating to maintain accuracy and prolong service life.
