Drill Bit Bosch 2609255089 1.5 mm Diameter 40 mm Length

The Bosch 2609255089 drill bit has a 1.5 mm diameter and a 40 mm overall length, engineered for precision drilling tasks. Designed for use in a range of materials, this slim twist bit produces clean, accurate holes with minimal wandering. Its compact diameter and extended length make it suitable for detailed work where access is limited and hole quality is important.

Advantages

This 1.5 mm drill bit delivers fine control and repeatable hole diameter, enabling precise component placement and neat finish in delicate assemblies. The 40 mm length provides extra reach compared with standard short bits while maintaining stability during rotation. Manufactured by a recognized brand, the bit is produced to consistent tolerances to support reliable performance in precision tasks.

Suitable for

• Drilling printed circuit boards (PCBs) and electronic components
• Fine woodworking and model making
• Jewellery repair and small metalworking tasks
• Hobbyist and DIY precision drilling

Key specifications

• Diameter: 1.5 mm
• Overall length: 40 mm
• Type: straight twist drill bit for general precision drilling
• Recommended use: light-duty materials and precision applications

How to use

Select an appropriate drill speed and clamping method for the material being worked. Secure the workpiece to prevent movement and fit the bit into a compatible chuck or rotary tool. Use steady, controlled pressure and avoid excessive force to prevent bit breakage. For thin or brittle materials, consider backing the workpiece to reduce splintering. Periodically clear chips from the hole to maintain drilling accuracy.

Usage recommendations

For best results, use this 1.5 mm bit at medium to high spindle speeds suitable for small-diameter bits, and reduce feed pressure to avoid bending or snapping. When drilling PCBs or other delicate substrates, use magnification and steady fixturing to ensure precise alignment.
