Drill bit GRAPHITE T 57H356 spiral wood hex shank 10 mm

Spiral wood drill bit GRAPHITE T 57H356 10 mm with hex shank is designed for drilling precise, clean holes in timber and wooden materials. The spiral flute geometry efficiently evacuates chips while the 10 mm diameter provides a standard-size hole for dowels, screws and fittings. The hex shank ensures secure mounting in handheld drills and cordless drivers with quick-change chucks, reducing slippage during drilling.

Advantages

The spiral design offers fast chip removal and reduced clogging, enabling smoother drilling and improved hole quality in soft and hardwood. The hexagonal shank provides reliable torque transfer and easier bit changing in compatible chucks or bit holders. Robust construction maintains concentricity and straight drilling over repeated use.

Suitable for

• Drilling holes in solid wood, plywood and laminated board
• Carpentry and joinery tasks such as dowel and hinge installation
• General woodwork with handheld drills and cordless drivers that accept hex shanks

Key specifications

• Drill type: spiral (auger-style) wood bit
• Diameter: 10 mm
• Shank type: hexagonal for secure mounting
• Material: hardened steel suitable for woodworking
• Flute: spiral for chip evacuation

How to use

Select a suitable drill or driver that accepts hex shanks and secure the bit in the chuck or bit holder. Mark the drilling position on the workpiece and clamp or support the timber to prevent movement. Start drilling at low speed to establish the hole, then increase speed as needed while applying steady, even pressure. Withdraw the bit periodically on deep holes to clear chips and avoid overheating.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For clean edges, back the workpiece with sacrificial material to reduce tear-out. Match drill speed to wood type—lower speeds for hard woods, higher speeds for soft woods—and avoid excessive side loads to prolong bit life.
