Drill bit Bosch 2609255408 8 mm diameter 120 mm length

The Bosch 2609255408 drill bit with an 8 mm diameter and 120 mm overall length is designed for precision drilling in a range of common materials. Its geometry and material selection aim to provide accurate hole placement and consistent performance for professional and DIY tasks that require a medium-diameter bit with extended reach.

Advantages

The 8 mm, 120 mm drill bit offers a balance of stiffness and reach that helps maintain drilling accuracy in deeper holes. Its construction supports wear resistance during repeated use and ensures stable cutting behavior to reduce wander at the start of drilling. The length provides access to recessed or hard-to-reach points while the standard diameter fits many common fasteners and dowel sizes.

Suitable for

• Drilling medium-diameter holes in wood for dowels and fixtures
• General-purpose drilling in soft metals and plastics where an 8 mm hole is required
• Tasks that require drilling into recessed areas or through thicker material sections

Key specifications

• Diameter: 8 mm
• Total length: 120 mm
• Intended use: precision drilling for general-purpose applications
• Compatibility: suitable for standard drill chucks that accept 8 mm shanks
• Construction: engineered for wear resistance and stable cutting action

How to use

Secure the drill bit in a compatible drill chuck and ensure it is tightened to prevent slippage. Select the appropriate rotational speed for the material being drilled — lower speeds for metals, medium-to-high speeds for wood and plastics. Begin drilling with steady, even pressure and allow the bit to remove chips without forcing it. For deep holes, periodically withdraw the bit to clear debris and reduce heat buildup. Use appropriate clamping and personal protective equipment.

Usage recommendations

Use cutting lubricant when drilling hard metals to extend tool life. Match drilling speed and feed to the material, and avoid excessive side loads to maintain hole quality and bit longevity.
