Dormer P821 Bright Ball Nosed Cone Carbide Burr

The 16mm diameter Dormer P821 Bright Ball Nosed Cone Carbide Burr is the largest variant in the range, designed for heavy-duty machining operations requiring maximum material removal capability. With a substantial 16mm diameter cut and 33mm cut length, this burr is ideal for large-scale tasks including enlarging significant bore sizes, blending large surface areas, and creating substantial radiused edges on heavy components.

Constructed from solid carbide with a bright finish, this robust burr handles the most demanding materials with confidence, including steel, cast steel, stainless steel, cast iron, copper alloys, high-temperature alloys, and hardened metals. The double cut geometry provides aggressive stock removal whilst maintaining excellent control and surface finish quality. Despite its large cutting head, the 6mm shank diameter maintains compatibility with standard rotary tools. This professional-grade burr is essential for heavy fabrication shops, maintenance facilities, and serious home workshops tackling substantial metalworking projects.
