Why this burr set matters Delivers long-lasting, sharper cutting on hard materials thanks to premium industrial-grade C3 micro-grain carbide. Reduces finishing time and rework by producing clean cuts and minimal burrs. Precisely balanced and heat-resistant for smooth, stable operation under high speed. Key features and benefits Material: C3 micro-grain carbide tips for high hardness, excellent wear resistance, and consistent cutting performance. Coating: Heat-resistant surface treatment extends tool life and maintains cutting sharpness during heavy use. Smooth operation: Precisely balanced cutters reduce vibration for more accurate, comfortable work and longer tool life. Durable cutting edge: Sharp, wear-resistant teeth maintain shape and cutting quality through repeated use. Includes a bearing at the bottom end for stable mounting and reliable rotation. Specifications Shaft diameter (shank): 8 mm — fits tools that accept an 8 mm shank. Cutting diameter: 15.9 mm. Cutting height options: 30 mm, 40 mm, 50 mm. Total length options: 75 mm, 84 mm, 94 mm (corresponding to cutting heights). Construction: Carbide cutting tips with heat-resistant coating. Compatible use Use in rotary tools, die grinders, and other machines that accept an 8 mm shank. Suitable for high-speed metalworking where a durable, sharp burr is required. Practical applications (examples) Weld cleanup and blend: Quickly remove weld beads and blend seams on steel and stainless steel with clean, burr-free results. Deburring and edge profiling: Smooth sharp edges and shape holes or openings on castings, pipe fittings, and metal parts. Precision shaping and material removal: Contour and refine cast iron, non-ferrous metals, hard plastics, or wood where a consistent cutter diameter and long cutting height are needed. What to expect in use Fast material removal with smooth rotation and minimal vibration. Long service life under typical high-speed grinder conditions thanks to carbide construction and heat-resistant coating. Consistent 15.9 mm cutting diameter across available cutting heights for repeatable results. Ordering notes Choose the cutting height/total length combination that matches the depth of work you need: 30 mm/75 mm, 40 mm/84 mm, or 50 mm/94 mm. Shank diameter is 8 mm; verify tool collet or chuck compatibility before use.
