Drill Bit for Wood DeWalt 12 x 155 mm DT4512

Drill Bit for Wood DeWalt 12 x 155 mm DT4512 is a high-precision twist/auger style bit engineered for clean, accurate holes in soft and hardwoods. With a 12 mm cutting diameter and 155 mm total length, this DeWalt wood bit is suitable for common carpentry and joinery work. It fits standard drill chucks and can be used in both handheld drills and drill presses; selecting appropriate speed and steady feed ensures optimal hole quality and long tool life.

Advantages

The bit delivers a precise 12 mm bore with minimal tear-out thanks to its sharp cutting edges and geometry designed for wood. Its 155 mm overall length provides deeper reach than shorter bits while remaining manageable in handheld applications. Compatibility with standard chucks makes it versatile across different drilling machines and jobsite tools. The construction and finish reduce friction and help maintain cutting performance during repetitive use.

Suitable for

• Carpentry and framing tasks requiring accurate through-holes or dowel holes
• Furniture assembly and cabinetry where clean edge holes are needed
• Door and window installation for hinge and lock fitting
• General woodworking tasks in both softwoods and hardwoods

Key specifications

• Cutting diameter: 12 mm
• Total length: 155 mm
• Material suitability: softwood and hardwood
• Chuck compatibility: standard keyed or keyless chucks
• Design: wood-specific cutting geometry for clean holes

How to use

Install the bit securely in the drill chuck and tighten according to the drill manufacturer's instructions. Select a moderate drill speed appropriate for a 12 mm bit and the wood species—lower speeds for hardwoods and higher speeds for softer woods—while applying steady, even pressure. For through-holes, back up the workpiece or use masking tape on the exit side to reduce splintering. Withdraw the bit occasionally on deep holes to clear chips and prevent clogging.

Usage recommendations

Use suitable personal protective equipment, clamp the workpiece to prevent movement, and follow recommended speeds for material type to extend bit life and achieve the cleanest holes. For repetitive production work, periodically inspect cutting edges for wear and replace the bit when hole quality degrades.
