These 3mm Round Nose Cylinder Tungsten Carbide Burrs are ideal for precise material removal, carving, and defining. Sometimes referred to as ball nose carbide burrs, they’re used to create concave cuts, hollow out areas, and shape or smooth flat surfaces and rounded edges.

Perfect for cutting, carving, and engraving hard materials such as metals, stone, ceramic, porcelain, bone, antler, plastics, and wood. Use with your rotary tool, flexible shaft, or die grinder. Recommended cutting speed: up to 35,000 RPM.

As well as being a favourite with jewellers and precision engineers, these burrs are also used by window and glazing companies for cleaning uPVC welds, deburring aluminium frames, and tidying drainage slots or hardware recesses. The rounded end lets you work neatly in corners and channels without marking the surrounding surface. Perfect for finishing, repairs, and maintenance on uPVC and aluminium window frames.
