Drill Bit Bosch 2609255098 5 mm Diameter 86 mm Length

The Bosch 2609255098 5 mm Diameter 86 mm Length drill bit is a single straight-shank bit designed for precision drilling tasks. With a 5 mm cutting diameter and an overall length of 86 mm, this drill bit suits through-holes and deeper pilot holes where accuracy and clean hole edges are required. The bit is intended for general drilling applications across common workshop and on-site materials.

Advantages

This 5 mm drill bit offers a balanced combination of rigidity and reach thanks to its 86 mm length, which helps maintain straight drilling in core materials. The geometry of the cutting edges is optimized for accurate centring and reduced walking at the start of the hole. Manufactured to meet Bosch quality standards, the bit provides consistent hole diameter and durability under normal drilling conditions, making it appropriate for repeated use in both professional and DIY environments.

Suitable for

• Drilling pilot holes in wood and composite materials
• Light to medium drilling tasks in plasterboard and soft masonry
• Precision dowel and screw pilot holes for furniture assembly
• General workshop drilling where a 5 mm diameter is required

Key specifications

• Cutting diameter: 5 mm
• Overall length: 86 mm
• Shank type: straight shank suitable for standard drill chucks
• Intended use: general-purpose drilling in wood, soft masonry, and common composites
• Finish and material: manufactured to Bosch quality standards for wear resistance and dimensional stability

How to use

Secure the drill bit in a properly rated drill chuck and tighten firmly. Select a drill speed appropriate for the material: higher speeds for wood and lower speeds for masonry or composites. Start drilling with light pressure to establish the hole and then apply steady, even force until the required depth is reached. Periodically withdraw the bit to clear chips and reduce heat buildup, especially in deeper holes. Ensure correct personal protective equipment and clamp the workpiece when precision or safety is required.

Usage recommendations

For best results, use the bit for pilot holes and general-purpose drilling in wood, soft masonry and composite panels. Avoid excessive side force and overheating; if drilling harder materials, select a drill bit specifically rated for those materials to preserve cutting geometry and service life.
