Drill bit GRAPHITE spiral hex shank for wood 16 mm (57H362)

Spiral wood drill bit by GRAPHITE with a 16 mm cutting diameter and a hexagonal shank designed for reliable grip in chucks and fast bit changes. This drill bit is shaped to cut clean, accurate holes in solid wood and common wooden components. It is compatible with hand-held and bench drills that accept hex shanks and is intended for use in carpentry, furniture assembly, joinery and general woodworking tasks where a tidy bore and controlled chip removal are required.

Advantages

The spiral flute geometry ensures efficient chip evacuation and reduces clogging when drilling deeper holes. The 16 mm cutting diameter provides a balance between material removal and hole precision for typical woodworking applications. The hex shank offers secure retention in quick-change chucks and manual drill chucks that accept hex-drive bits, reducing slippage during high-torque operations. The overall design promotes straight drilling and improved centring compared with non-specialised bits.

Suitable for

• Drilling through soft and hardwood boards and planks
• Furniture assembly and dowel preparation
• Joinery and cabinetry holes for fittings
• General repair and renovation woodwork

Key specifications

• Cutting diameter: 16 mm
• Shank type: hexagonal (hex shank) for quick-change chucks
• Flute: spiral for chip evacuation
• Material: hardened tool steel suitable for wood cutting
• Intended use: drilling solid wood and wooden components

How to use

Secure the hex shank in a compatible drill chuck or quick-change holder, ensuring the shank is fully seated. Mark the drilling point and, if precise positioning is required, use a centre punch or pilot mark. Operate the drill at a moderate speed appropriate for the wood species; higher speeds suit softer woods while harder woods require slower feed rates and steady pressure. Apply consistent axial pressure, withdraw occasionally to clear chips when drilling deep holes, and finish the hole with a steady, reduced feed to avoid splintering on exit.

Usage recommendations

Use cutting lubricant or dust extraction when working with resinous or treated woods to maintain cleaner flutes. Store the bit in a dry place and inspect for wear or chipping before use; replace when the cutting edge becomes dull to maintain hole quality and reduce load on the drill motor.
