Double Thread Design: Shaft diameter: 1/8 inch(3mm); Rotary Burr Bit Size: 6mm. The dual-wire design of the cutter head produces a finer finish than single-wire cutting, clean and fast cuts in hardened steel with a smoother surface
High Speed: The speed is generally 6000-30000 rpm.Too high speed may bend the shaft .Rotary Burr Bits is made of Tungsten Carbide, which is high hardness, sharper, heat resistance and long working life, better resistance to chipping and corrosion, and faster cutting efficiency
Elaborate Processing: The carefully designed cutting edge of each burr is sharp, and the individual burrs of different shapes and sizes can be easily created. Suitable for operation in confined spaces, it ensures long-lasting performance under high impact and resists wear and tear
Easy to Operate: Carbide Rotary Tool Bits are of good quality, comfortable to use, easy to control, works with low vibration and low noise, and makes it easy to make clean cuts without much effort
Multi Purpose: Carbide Rotary Drill Bits can be used to process all kinds of metal and non-metal engraving, polishing and removing sharp edges, suitable for wood carving, stone carving, metal processing and molded grinding machines
