The CMT Forstner Bit 529.250.31 is a precision woodworking tool designed for clean, accurate drilling of flat-bottomed holes in wood and wood-based materials. Featuring a 25 mm cutting diameter, a 13 mm shank, a total length of 140 mm, 5 flutes, and right-hand rotation, this drill bit is ideal for professional cabinet making, furniture production, and intricate joinery applications requiring high accuracy and smooth surface finishes.

Advantages

This Forstner bit provides exceptional drilling precision, allowing users to create smooth flat-bottomed holes and clean edge cuts without splintering the surrounding material. The inclusion of five flutes ensures efficient chip evacuation and stable performance during operation. Built for demanding professional environments, the robust construction supports reliable repetition work in solid wood, MDF, and plywood.

Suitable for

• Drilling flat-bottomed holes for concealed hinges and hardware
• Professional cabinetry and furniture manufacturing
• Precision woodworking and joinery projects
• Working with solid wood, particle board, MDF, and plywood

When it may not be suitable

This tool is not designed for drilling through metals, stone, ceramics, or abrasive composite materials, as this will quickly dull the cutting edges. It is also unsuitable for standard hand-held twist drill tasks where hole bottom flatness is not required.

Key specifications

• Cutting diameter: 25 mm
• Shank diameter: 13 mm
• Total length: 140 mm
• Number of flutes: 5
• Rotation direction: Right-hand
• Material application: Wood and wood-based panels

How to use

Secure the 13 mm shank firmly into the drill press chuck or compatible heavy-duty drilling machine to ensure stability and safety during use. Align the center point of the bit with the marked location on the workpiece. Start the machine at the recommended speed for woodworking and feed the bit steadily into the material, allowing the flutes to clear out wood chips continuously. Avoid excessive force to maintain a clean cut and prolong the lifespan of the cutting edges.

What to consider before purchase

• Verify that your drilling equipment or drill press chuck can securely accommodate a 13 mm shank.
• Ensure the 25 mm cutting diameter matches the exact requirements of your project or hardware.
• Confirm that your machinery supports right-hand rotation bits.

Usage recommendations: Always wear appropriate eye protection and safety gear when operating woodworking tools. Keep the cutting edges clean and free of resin buildup to ensure consistently accurate drilling results.
