The Great White Lab Series Carbide Bur (M Series, ISO 275) is a laboratory handpiece bur with a round-end taper spiral-fluted head, manufactured with a tungsten carbide head and stainless steel shank. Its extremely hard 2,800 Vickers cutting surface delivers up to 10x increased durability and longevity, while abrasion resistance reduces surface heat and vibration for a cooler, more consistent finish. The M Series is designed for trimming plaster and stone and bulk reduction of acrylic, with a maximum recommended speed of 20,000 RPM and a blue color band for quick identification.
