Drill bit Bosch 5 mm HSS 2609255635 for metal and general drilling

Bosch 5 mm HSS drill bit 2609255635 is a high-speed steel cutting tool designed for metalworking and general drilling tasks. The 5 mm diameter and standard twist configuration make it suitable for creating precise holes in a range of materials when used with appropriate drilling speeds and cooling. Manufactured to Bosch quality standards, the bit fits standard chucks and is intended for routine workshop, maintenance and construction use.

Advantages

The HSS material provides enhanced wear resistance and heat tolerance compared with carbon steel bits, supporting consistent cutting performance during prolonged use. The 5 mm diameter gives a common, versatile hole size for fasteners and fittings, and the twist geometry promotes chip evacuation and steady drilling. The bit’s compatibility with standard drills simplifies tool selection and replacement.

Suitable for

• Drilling holes in ferrous and non-ferrous metal sheets and components
• General-purpose workshop and maintenance drilling
• Creating pilot holes for screws or fasteners in metal and plastic
• Repair and fabrication tasks requiring small-diameter holes

Key specifications

• Material: high-speed steel (HSS)
• Diameter: 5 mm
• Geometry: standard twist drill
• Intended materials: metal, plastic and other softer materials when appropriate technique is used
• Shank type: cylindrical for standard drill chucks

How to use

Secure the drill bit in a compatible chuck and tighten firmly. Select an appropriate spindle speed for the workpiece material—lower speeds for larger diameters and harder metals, higher speeds for softer materials. Use cutting fluid or coolant when drilling metal to reduce heat build-up and extend tool life. Apply steady, moderate pressure and allow the bit to cut without excessive force; periodically withdraw the bit to clear chips if drilling deep holes.

Usage recommendations

For best results when drilling metal, use cutting fluid and maintain recommended speeds for HSS tools. Pre-centre or use a punch on thin sheets to prevent wander. Replace the bit when wear or bluntness reduces hole quality; reconditioning is possible on appropriate grinding equipment but must preserve correct point angle.
