Drill bit Bosch 4 mm diameter model 2608901480 for metal and wood drilling

Bosch 4 mm drill bit model 2608901480 is intended for precision drilling in common materials such as metal and wood. The straight-shank design fits standard drill chucks and delivers a consistent 4 mm hole diameter for assembly, mounting and repair tasks. Its compact size and compatibility make it convenient for both professional and home use where a reliable small-diameter hole is required.

Advantages

The drill bit offers accurate hole diameter control and stable running thanks to a precisely ground tip and uniform shaft. It is suitable for repeated use in mixed material applications, providing predictable drilling depth and clean hole edges in wood and many metals. The universal shank design enables quick installation in corded and cordless drills without adapters.

Suitable for

• Drilling pilot and finish holes in wood for furniture assembly and carpentry
• Making small-diameter holes in thin metal sheets and brackets for fasteners
• General repair and maintenance tasks that require a 4 mm hole
• DIY projects, hobby work and light construction tasks

Key specifications

• Diameter: 4 mm
• Material suitability: metal and wood
• Shank type: straight shank for standard drill chucks
• Intended use: through-holes and pilot holes in thin to medium thickness materials

How to use

Secure the drill bit in the chuck and tighten according to the drill manufacturer's instructions. Select an appropriate drilling speed for the material: lower speeds for metal and moderate to higher speeds for wood. Apply steady, even pressure and allow the drill bit to do the cutting; withdraw periodically when drilling deeper holes to clear chips. Use cutting fluid or lubrication when drilling harder metals to reduce heat and extend bit life.

Recommendations

Inspect the bit for damage before use and replace if worn or chipped. Wear appropriate eye and hand protection. For best results in metal, mark the drilling point and consider a center punch to prevent wandering. Store the drill bit in a dry place and avoid excessive side loading during operation to maintain accuracy.
