Drill Bit Bosch 2609255069 4.2mm Diameter 75mm Length

The Bosch 2609255069 drill bit has a 4.2 mm diameter and a 75 mm overall length, engineered for precision drilling tasks. Manufactured by Bosch for use with standard drills, this accessory is intended to deliver consistent, clean holes in a range of common materials. The bit's dimensions support accurate depth control and make it suitable for both tight-tolerance work and routine drilling operations.

Advantages

The 4.2 mm diameter and 75 mm length provide a balance between reach and rigidity, reducing wobble during drilling. Built to Bosch quality standards, the drill bit is designed for reliable performance and repeated use. Its geometry supports efficient cutting and chip removal, contributing to cleaner hole edges and minimized material damage.

Suitable for

• Precision drilling in wood
• Drilling in plastic components and panels
• Light- to medium-duty metal drilling where a 4.2 mm hole is required
• DIY projects and professional repair tasks requiring accurate hole placement

Key specifications

• Diameter: 4.2 mm
• Overall length: 75 mm
• Manufacturer brand: Bosch
• Application: general-purpose precision drilling

How to use

Select an appropriate drilling speed and clamp the workpiece securely before using the Bosch 4.2 mm drill bit. Fit the bit into a compatible drill chuck and align the tip with the marked drilling point. Apply steady, even pressure and allow the bit to cut without forcing; withdraw occasionally if drilling deeper to clear chips. After use, inspect the cutting edges for wear and store the bit in a dry place to preserve its condition.

Usage recommendations

For best results, match drilling speed to the material being worked: lower speeds for harder metals and higher speeds for wood and plastics. Use appropriate lubrication when drilling metal to extend tool life. Replace the bit if cutting performance decreases or if the tip is visibly damaged.
