Countersink cutting discs Makita B-64886, 32 mm diameter, set for metal and wood cutting

Makita B-64886 countersink cutting discs, 32 mm diameter, are designed for use with compatible rotary tools and countersink attachments to perform precise chamfering, deburring and small-diameter cutting in metal and wood. The compact discs allow operators to enlarge holes, remove burrs and finish edges in confined areas where larger tools cannot reach. Intended for workshop and onsite jobs, these cutting discs deliver controlled material removal for finishing and preparation tasks.

Advantages

The small 32 mm diameter offers access to tight spaces and enables accurate chamfering and hole enlargement without excessive material removal. These discs are suitable for both metal and wood, providing versatility across common fabrication and repair tasks. Their design reduces vibration and facilitates controlled cutting, helping to maintain consistent results when finishing edges or deburring components.

Suitable for

• Chamfering and countersinking holes in metal and wood
• Deburring edges and removing sharp flashes
• Enlarging or shaping small-diameter openings
• Detail finishing in tight or confined areas

Key specifications

• Diameter: 32 mm
• Material compatibility: metal and wood
• Intended tool type: rotary tools and countersink attachments
• Application: chamfering, deburring, hole enlargement, edge finishing
• Design: compact disc for access to confined spaces

How to use

Install the disc into a compatible rotary tool or countersink attachment according to the tool manufacturer’s instructions, ensuring a secure fit and correct orientation. Select an appropriate rotational speed for the material—lower speeds for harder metals, moderate speeds for wood—and apply light, steady pressure while guiding the disc along the work surface. Make multiple light passes rather than heavy cuts to avoid overheating and to retain control over the finish. Wear appropriate personal protective equipment, including eye protection, gloves and hearing protection, and ensure the workpiece is securely clamped.

Usage recommendations

Use progressive, light passes and match rotational speed to the work material. Inspect the disc before use for wear or damage and replace it if deterioration or imbalance is detected. Store discs in a dry, stable environment to prevent warping or contamination.
