Key specifications

• Working length: 130 mm
• Tool type: manual hand reamer / deburring tool
• Suitable materials: metals and plastics
• Operation: hand-operated, no power required
• Application: internal and external edge finishing and chamfering

How to use

Secure the workpiece to prevent movement. Position the reamer on the edge or inside the bore where the burr is present and apply steady, controlled strokes while rotating the tool by hand. For internal edges, insert the working end and rotate while withdrawing slightly to create a uniform chamfer. For external edges, move the tool along the edge with consistent pressure until the edge is smooth. Inspect the edge frequently and remove small amounts of material to avoid overcutting.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Keep the tool clean and free of chips during use to maintain cutting performance. For harder materials, use slower strokes and check the edge frequently. Store the reamer in a dry place to prevent corrosion and inspect before use for signs of wear.
