Drill Bit GRAPHITE 24 mm Spiral Hex Shank for Wood, Model 57H370

GRAPHITE Spiral Drill Bit 24 mm (model 57H370) is a wood-cutting twist bit designed for general woodworking. The 24 mm cutting diameter and spiral flute geometry provide efficient chip evacuation when drilling through soft and hard timber. A hexagonal shank ensures secure retention in quick-change bit holders and chucks that accept hex shanks, enabling stable drilling with both cordless and corded drills.

Advantages

The spiral flute accelerates chip removal to reduce clogging and improves drilling speed and surface finish. The 24 mm diameter offers a balance between material removal and control for common woodworking tasks. The hex shank design provides a reliable anti-rotation fit in compatible holders, facilitating quick bit changes and reducing slippage during use. The bit is suitable for a range of drill powers and ergonomic setups that accept hex shanks.

Suitable for

• Drilling 24 mm diameter holes in soft and hard wood
• General woodworking tasks such as shelving, furniture assembly, and joinery
• Use with cordless and corded drills that accept hex shank bits
• Quick bit change applications with hex bit holders and magnetic adapters

Key specifications

• Cutting diameter: 24 mm
• Flute type: spiral (twist) for chip evacuation
• Intended material: wood (soft and hard timber)
• Shank type: hexagonal for secure grip in compatible holders
• Compatibility: suitable for cordless and corded drills accepting hex shanks

How to use

Secure the hex shank in the drill chuck or quick-change holder, ensuring the bit is seated firmly. Start drilling at low speed to establish the hole and then increase speed as needed while applying steady, moderate pressure. Allow the spiral flutes to remove chips; withdraw the bit periodically for deep holes to clear debris and prevent overheating. Use appropriate clamping of the workpiece to maintain accuracy and safety.

Usage recommendations

For best results, select drill speeds appropriate for the timber type: lower speeds for hard woods and higher speeds for softer woods. Maintain a steady feed rate, avoid excessive lateral forces, and inspect the bit for wear or damage before use. Use protective equipment and secure the workpiece when drilling.
