Round File Makita D-73782 5.5 mm

Makita D-73782 5.5 mm round file is a compact hand tool designed for shaping, smoothing and enlarging round holes and concave surfaces. With a 5.5 mm diameter profile, this round file provides controlled material removal on metal, wood and plastic depending on user technique and file grade. Its compact size and precise geometry make it suitable for maintenance, metalworking, woodworking and hobby tasks that require accurate finishing and subtle adjustments.

Advantages

The round file delivers consistent cutting action along a curved profile, allowing even material removal and improved surface finish in confined or circular areas. Its 5.5 mm diameter provides a balance between control and cutting capacity for small to medium detail work. The tool is versatile across multiple materials when matched with appropriate pressure and stroke technique, and its compact form enables access to tighter spaces than larger files.

Suitable for

• Enlarging and finishing round holes in metal plates and sheet
• Shaping concave wooden or plastic surfaces
• Deburring edges of drilled holes and castings
• Fine adjustments in maintenance and repair work
• Model making and other hobbyist detailing tasks

Key specifications

• Profile: round
• Diameter: 5.5 mm
• Intended materials: metal, wood, plastic (application depends on technique)
• Use type: hand filing for shaping and smoothing
• Typical applications: hole enlargement, concave surface finishing, deburring

How to use

Secure the workpiece to prevent movement, then select a steady, controlled stroke that follows the curvature of the hole or concave surface. Apply light to moderate pressure and check progress frequently to avoid removing too much material. For metals, use long, even strokes and maintain consistent angle; for wood and plastic, shorter strokes and lighter pressure help prevent gouging. Clean the file teeth regularly with a file card or brush to maintain cutting efficiency and prevent clogging.

Usage recommendations

Use eye protection and gloves when filing metal or brittle materials. Match the filing technique to the material: firmer, steady strokes for metal; lighter, careful strokes for wood and plastic. Keep the file clean and store it in a dry place to prolong service life.
