Drill bit GRAPHITE spiral hex shank for wood 8 mm (T 57H354)

Spiral wood drill bit GRAPHITE with an 8 mm working diameter and a hexagonal shank. This bit is designed for drilling clean, precise holes in solid wood and wood-based materials. The spiral flute geometry removes chips efficiently to reduce clogging and improve cutting performance, while the hex shank provides a secure grip in hex chucks and quick-change adapters for handheld drills and drill drivers.

Advantages

The spiral flute design promotes rapid chip evacuation and smoother drilling in soft and hardwoods. The hexagonal shank reduces slippage in the chuck and enables fast bit changes in quick-change systems. The 8 mm diameter is suitable for many common woodworking fittings and dowel holes, delivering consistent hole size with minimal tear-out when used correctly.

Suitable for

• Drilling holes in solid wood
• Work with plywood, particleboard and medium-density fiberboard (MDF)
• Preparing holes for dowels, screws and fittings
• Handheld drill and drill-driver use in carpentry and furniture assembly

Key specifications

• Working diameter: 8 mm
• Shank type: hexagonal shank for secure grip
• Tip and flute: spiral flute for efficient chip removal
• Material compatibility: solid wood and wood-based panels
• Intended tool: handheld drills and drill drivers

How to use

Secure the bit in a compatible hex chuck or quick-change holder and tighten according to the drill manufacturer's instructions. Use moderate feed pressure and appropriate rotational speed for the wood species to avoid burning or tear-out. If drilling deep holes, periodically retract the bit to clear chips and maintain cutting efficiency. Use clamps or supports to stabilise workpieces for accurate holes.

Usage recommendations

For best results, match drill speed to the wood type—higher speeds for softwoods, lower speeds for dense hardwoods—and ensure the workpiece is firmly fixed. Inspect the bit before use for any damage, and replace it if the cutting edges are worn to maintain hole quality and safe operation.
