Diamond Burr Set Activeshop 10 pieces — rotary tool bits for grinding, shaping, engraving

Activeshop Diamond Burr Set — 10 pieces — rotary tool bits designed for precision grinding, shaping, carving and engraving on hard materials. Each bit features a diamond-coated head mounted on a durable steel shank compatible with most rotary tools and die grinders. The set covers a range of head shapes and sizes to handle fine detail work and light material removal on glass, ceramics, stone, metal and hard plastics. The bits are intended for hobby, craft and small workshop applications that require accurate, repeatable results on brittle or abrasive surfaces.

Advantages

The diamond-coated heads provide high hardness and wear resistance for longer life when working on abrasive materials. A variety of shapes in the 10-piece set allows versatile use for contouring, hollowing, slotting and surface finishing. Standard steel shanks ensure compatibility with most rotary tools and collet sizes commonly used in home workshops and light professional work. The set is compact for easy storage and quick selection during projects.

How to use

Select a burr shape appropriate to the task and secure it in the rotary tool collet according to the tool manufacturer’s instructions. Start at low to medium speed to establish control, then increase speed as needed for material and burr size. Apply light, consistent pressure and move the burr along the workpiece to avoid overheating and premature wear. Use water or a coolant when working on glass, ceramics or stone to reduce dust and heat; clean the burrs after use to remove residues and extend service life.

Usage recommendations

For safe and effective operation, wear eye protection, a dust mask and appropriate gloves. Avoid excessive pressure and high speeds that can chip brittle materials or damage the diamond coating. Store the set in a dry place and inspect burrs regularly for wear; replace worn cutters to maintain precision and reduce the risk of workpiece damage.
