Collection: Sintered Diamond Burrs

Sintered Diamond Burrs from Eternal Tools are made with multiple layers of premium diamond grit, giving you a longer-lasting, free-cutting tool that maintains sharpness for years. Ideal for carving, shaping, and grinding hard materials such as glass, stone, ceramics, and even tough hardwoods. Perfect for use with a pendant drill, micromotor, or flexible shaft rotary tool.

Unlike coated burrs, the diamond grit runs throughout the entire head, so as it wears, fresh diamonds are continually exposed. For best results, always use with water and dress regularly with an Aluminium Oxide Dressing Stick to reveal new cutting edges. Explore our entire range of Diamond Burrs, or Stone Carving Burrs.
