Carbide Rotary Burr is a very good tool to realize mechanization in hand work operations. Carbide alloy rotary burr is widely used in the fields of airplane, automobile, machinery, chemistry, ship building, etc., Carbide rotary burrs are also applied in machining iron, stainless steel, steel casting, alloy steel, carbon steel, copper aluminum etc. Functions of Carbide burrs and rotary files:1). Machining a variety of metals when their hardness is under HRC65.2). Grinding the hole to an accurate shape. 3).Increasing productivity of several ten times than using hand tools and three to five times than using small emery wheels 4).Having long life of ten times than high speed steel burrs and fifty times than small emery wheels. 5).Instead of small emery wheels, without powder pollution. 6).Finish machining various kinds of die cavities.7).Removing the burrs of the castings, forgings and the welding spatter on the weld assemblies. 8).Chamfering angle, circular bead or flute on the mechanical components. 9).Chamfering or burring the pipes. 10).Polishing the impeller channel.Any problem, please feel free to let us know!
