Lapidary Sintered Diamond Bur

The Sintered Diamond Bur is a heavy-duty precision tool engineered for high-speed grinding, shaping, and material removal on ultra-hard substrates like carbides, industrial ceramics, sapphire, and advanced composites. Featuring a sintered metal bond that permanently bonds diamond particles, it delivers unmatched durability and stability under extreme mechanical stress.

The Sintered Diamond Bur is a high-performance rotary tool accessory engineered for demanding grinding, shaping, and material removal  tasks. Constructed with a sintered diamond bond, this Bur features diamond particles embedded throughout the head—not just on the surface—delivering extended lifespan, superior cutting power, and excellent heat resistance under continuous use.

Perfect for professionals in stone carving, metalworking, semiconductor fabrication, and aerospace machining, this tool is compatible with Dremel rotary tools, CNC machines, and precision grinders. Whether you're refining synthetic gemstones, polishing industrial ceramics, or detailing hardened metals, it ensures stability and precision with every pass.
