Drill bit GRAPHITE 8 mm spiral wood cylindrical shank (57H275)

GRAPHITE spiral wood drill bit, 8 mm diameter with a cylindrical shank, is designed for creating clean, accurate holes in solid wood and engineered wood materials. The twisted flute geometry promotes efficient chip removal and stable cutting, reducing clogging during continuous drilling. This 8 mm drill bit is compatible with standard chucks on handheld drills and drill presses, making it suitable for routine carpentry and furniture assembly tasks.

Advantages

The spiral flute design ensures effective evacuation of wood chips and minimizes heat buildup, which helps preserve bit sharpness and hole quality. The cylindrical shank provides easy and secure clamping in most drill chucks, while the 8 mm diameter delivers a balance between precision and material removal rate. The bit is intended for general woodworking applications and offers consistent performance across a range of wood densities.

Suitable for

• Drilling holes in softwood and hardwood
• Furniture assembly and dowel hole preparation
• Carpentry, joinery and on-site repair work
• Use with handheld drills and stationary drill presses

Key specifications

• Drill type: spiral/twist wood drill bit
• Diameter: 8 mm
• Shank style: cylindrical (round) shank for standard chucks
• Material compatibility: solid wood and wood-based panels
• Flute: twisted spiral flute for chip removal and stable cutting

How to use

Secure the drill bit in the drill chuck, ensuring the shank is fully inserted and tightened. Mark the drilling point on the workpiece and, if needed, use a center punch or pilot mark to prevent walking. Start drilling at low speed to establish the hole, then increase speed as appropriate for the wood type and bit size. Apply steady, even pressure without forcing the bit; allow the flute to clear chips periodically to maintain cutting efficiency. After use, clean wood debris from the flutes and store the bit in a dry place to avoid corrosion.

Usage recommendations

For best results, match drill speed to the wood density: lower RPM for hardwoods, higher RPM for softwoods. When drilling deep holes, withdraw the bit occasionally to clear chips and prevent overheating.
