Circle cutter drill bit Cimco 208790

The Cimco 208790 circle cutter drill bit is a precision cutting tool with a diameter of 6.8 cm designed to create clean, round holes in a variety of materials. Constructed for durability, the cutter combines a robust body with sharp cutting edges to deliver consistent results for both professional and home workshop applications. The tool fits common drill chucks and is intended for tasks requiring accurate circular cuts without extensive finishing.

Advantages

This circle cutter drill bit offers a clear cutting diameter of 6.8 cm, stable rotation thanks to its balanced design, and long-lasting cutting performance due to wear-resistant materials. Its construction reduces vibration and provides straight, uniform cuts, minimizing the need for secondary processing. The tool is compatible with standard hand drills, enabling quick setup and efficient hole making.

Suitable for

• Cutting circular openings in wood and wood-based panels
• Creating holes in plastic and composite sheets
• Preparing openings for pipes, cables, and fittings
• General workshop and installation tasks requiring round holes

Key specifications

• Cutting diameter: 6.8 cm
• Intended use: manual drill or drill press compatibility
• Material: hardened cutting edges for extended wear resistance
• Design: balanced body to reduce vibration during rotation
• Typical applications: wood, plastics, and composite panels

How to use

Secure the circle cutter in a compatible drill chuck, ensuring concentric alignment and a tight hold. Mark the desired center point on the workpiece, position the pilot or center guide if provided, and start drilling at low speed to establish the cut. Increase speed gradually while maintaining steady pressure and keeping the drill perpendicular to the surface. For thicker or harder materials, make several shallow passes rather than a single deep cut to reduce load on the cutter and obtain a cleaner edge.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and hearing protection. Clamp the workpiece securely to prevent movement. For best results, select drill speed and feed rate according to material type: lower speeds for plastics and hard materials, moderate speeds for wood. Periodically inspect cutting edges and remove chips to maintain cutting efficiency.
