Drill bit Bosch 8 mm × 100 mm, model 2608680286, carbide-tipped twist drill

Bosch 8 mm × 100 mm carbide-tipped twist drill is a straight-flute drill designed for precise 8 mm holes in a range of common workshop materials. The carbide tip enhances cutting performance and increases wear resistance compared with plain-steel points, while the 100 mm overall length provides sufficient reach for typical hand-drilling and press operations. This drill bit is compatible with standard chucks on handheld drills and drill presses, intended for use where an accurate, clean hole in metal, wood or plastic is required.

Advantages

The carbide-tipped point ensures improved edge retention and longer life during repeated drilling. The twist-drill geometry promotes efficient chip evacuation and consistent hole quality. The 8 mm diameter and 100 mm length balance rigidity and reach for common repair, fabrication, and assembly tasks. Manufactured by a recognized brand, the drill bit is produced to consistent dimensional tolerances for repeatable results.

Suitable for

• Drilling 8 mm holes in mild steel, non-ferrous metals and sheet metal
• Creating pilot or through-holes in wood and laminated boards
• Plastic and composite material drilling for fastening and routing tasks
• General maintenance, repair and assembly with handheld drills or drill presses

Key specifications

• Diameter: 8 mm
• Total length: 100 mm
• Type: twist drill with carbide tip
• Shank style: straight cylindrical shank for standard chucks
• Material suitability: metal, wood, plastic
• Geometry: standard point angle for general-purpose drilling

How to use

Select a proper drill speed and clamping method for the material: lower speeds for harder metals, higher speeds for wood and plastics. Secure the workpiece to prevent movement and fit the 8 mm twist drill into a properly tightened chuck. Begin drilling with light axial pressure until the tip locates, then apply steady pressure and moderate feed to allow consistent chip removal. Withdraw periodically on deeper holes to clear chips and reduce heat build-up. Use cutting fluid or lubricant when drilling metals to extend tool life and improve hole finish.

Usage recommendations

For best results, match drill speed and feed to the workpiece material, use appropriate cutting fluid for metalworking, and ensure the drill and workpiece are securely clamped. Inspect the carbide tip before use and replace the bit if chipping or excessive wear is observed.
