Carbide burrs, also called carbide rotary burrs are used with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are popular in machinery, automobile, shipbuilding, chemical industry, craft carving, and other industries. Choosing the proper carbide burr for your project is crucial. There are lots of options for choosing a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form of the carbide rotary burr needs to be based on the design from the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs needs to be selected; when processing the inner right angle surface, a flat burr and square burr might be selected. If the flat burr is employed to slice the interior right angle surface, it is crucial to produce a narrow surface (smooth edge) without teeth near to among the inner right angle surfaces, in an attempt to avoid damaging the correct angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth ought to be determined according to the allowance sized the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr works for machining workpieces with large allowance, low dimensional accuracy, large form and position tolerance, large surface roughness value, and soft material; otherwise, fine-tooth carbide burr ought to be selected. When used, it ought to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness required by the workpiece.
Sizes of carbide burrs
The size and style and specification of cemented carbide rotary burr must be selected according to the size of the workpiece and machining allowance. Once the machining sizing is large and the allowance is large, cemented carbide rotary burr having a large size should be selected, or a tungsten carbide rotary burr having a small size should be selected instead.
