Drill bit GRAPHITE spiral wood hex shank 14 mm 57H360

Spiral wood drill bit by GRAPHITE with a 14 mm cutting diameter and a hexagonal shank, designed to produce clean, accurate holes in solid wood and wood-based materials. The spiral flute geometry efficiently evacuates chips, reducing clogging and heat buildup during continuous drilling. The hex shank ensures a secure grip in hand drills and impact drivers that accept hex accessories, allowing stable drilling performance for carpentry, joinery and general woodworking tasks.

Advantages

The spiral design promotes rapid chip removal and smoother cutting, which helps maintain hole quality and reduces the need for rework. A 14 mm cutting diameter provides a mid-sized option for dowel holes, fastener clearance and other common woodworking joints. The hex shank minimizes slippage in chucks with hex receptacles and enables quick bit changes without additional adapters. The solid construction and sharp cutting edges help deliver consistent results in both soft and hard wood varieties.

Suitable for

• Drilling clean holes in solid wood and plywood
• Installing dowels, bolts and wood fasteners
• Joinery and furniture assembly tasks
• DIY woodworking and carpentry projects

Key specifications

• Cutting diameter: 14 mm
• Shank type: hexagonal shank compatible with hex chucks
• Flute design: spiral for efficient chip removal
• Material and edge: hardened steel with ground cutting edges for wood

How to use

Secure the drill bit firmly in the hex chuck of a hand drill or impact driver. Mark the drilling position on the workpiece and, if necessary, clamp the workpiece to prevent movement. Start drilling at low speed to establish an accurate entry point, then increase speed while maintaining steady pressure. Allow the spiral flute to remove chips; periodically withdraw the bit to clear accumulated material when drilling deep holes. After completing the hole, withdraw the bit while the tool is still running slowly to reduce tear-out.

Usage recommendations

For best results, select drilling speeds appropriate to the wood species: lower speeds for hardwoods and higher speeds for softwoods. Use pilot holes for precise alignment when installing fasteners, and apply light cutting lubricant or compressed air for prolonged continuous use to reduce heat build-up. Inspect the bit for sharpness before use and replace or resharpen when edge wear affects hole quality.
