Drill bit GRAPHITE spiral hex shank for wood 8 mm (57H252)

Spiral wood drill bit by GRAPHITE with an 8 mm diameter and a hexagonal shank. Designed for drilling wood and wood‑based materials, this bit features a helical flute for efficient chip removal and a hex shank for a secure fit in chucks or bit holders. Suitable for use with hand drills and impact drivers, it is intended for general woodworking tasks, carpentry repairs and material preparation.

Advantages

The spiral flute ensures effective evacuation of wood chips and reduces clogging during continuous drilling. The hex shank provides improved torque transfer and resists slipping in quick-change chucks and bit holders. Precision ground tip and flute profile contribute to cleaner holes with consistent diameter, while the solid construction offers reliable performance in soft and medium-density wood and common wood-based panels.

Suitable for

• Drilling holes in solid wood and lumber
• Working with plywood, MDF and particleboard
• Carpentry repairs and furniture assembly
• Use with cordless hand drills and impact drivers
• Preparing anchor or dowel holes for fixings

Key specifications

• Diameter: 8 mm
• Shank type: Hexagonal shank for secure grip
• Tip and flute: Spiral/helical flute for chip removal

How to use

Select an appropriate drilling speed for the wood type and secure the bit in the drill chuck or bit holder by fully seating the hex shank. Start drilling with light pressure to establish the hole, then apply steady, even feed to allow the spiral flute to remove chips effectively. For deep holes, periodically withdraw the bit to clear accumulated chips and prevent overheating. Use appropriate personal protective equipment such as eye protection and hearing protection when operating power tools.

Usage recommendations

For best results, use moderate drill speeds on softwoods and lower speeds on hardwoods to reduce burning. When working with laminated or veneered panels, clamp the workpiece and consider using a sacrificial backing board to minimize tear‑out on the exit side.
