Drill bit GRAPHITE 57H276 spiral wood cylindrical 10 mm

GRAPHITE 57H276 is a 10 mm spiral (twist) cylindrical drill bit designed specifically for drilling wood. The bit has a helical flute for efficient chip evacuation and a smooth round shank for stable mounting in standard chucks. It is intended for producing dowel holes, pilot holes and through-holes in both soft and hard wood, providing consistent hole diameter and clean edges when used with appropriate drilling speed and guidance.

Advantages

The spiral flute geometry promotes rapid chip removal and reduces heat buildup during drilling, which helps maintain cutting performance and hole quality. The cylindrical, round shank enables secure clamping in handheld drills and drill presses without the need for an adapter. Its 10 mm diameter offers a common size for woodworking joinery and general-purpose drilling tasks.

Suitable for

• Drilling dowel holes for joinery and furniture assembly
• Creating pilot holes for screws in wooden components
• Making through-holes in softwoods and hardwoods
• General woodworking and cabinetry tasks

Key specifications

• Tip type: spiral (twist) with helical flute for wood chips
• Diameter: 10 mm
• Shank type: round (cylindrical) suitable for standard chucks
• Material: high-speed steel or similar tool steel suitable for wood drilling
• Intended material: wood (softwood and hardwood)

How to use

Secure the drill bit in the chuck with the round shank clamped firmly and set the drill to an appropriate speed for the wood type: higher speeds for softwoods and moderate speeds for hardwoods. Mark the drilling point and, if precise depth is required, use a depth stop or tape on the bit. Start drilling with steady pressure, allowing the spiral flute to clear chips; withdraw the bit periodically for deep holes to remove accumulated chips and avoid clogging. After drilling, inspect the hole and lightly sand edges if needed to remove splinters.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. For best results, clamp workpieces securely and pilot with a smaller bit when drilling near edges or in delicate parts. Avoid excessive axial force and high speeds in hardwoods to prevent bit overheating and premature wear.
