Carbide burrs, also referred to as carbide rotary burrs are employed 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, along with other industries. Choosing the right carbide burr to your project is essential. There are numerous strategies to selecting a high-quality tungsten carbide rotary burr.

Shapes of tungsten carbide rotary burrs
The design with the carbide rotary burr ought to be driven by the design in the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) should be used; when processing the interior corner surface, triangular burrs should be selected; when processing the inner right angle surface, a designated burr and square burr can be selected. If the flat burr is used to slice the interior right angle surface, it is necessary to generate a narrow surface (smooth edge) without teeth near to one of several inner right angle surfaces, so as to avoid damaging the proper angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth ought to be determined according to the allowance size the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr is acceptable 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 as outlined by machining allowance, dimensional accuracy, and surface roughness required by the workpiece.

Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr needs to be selected according to the size of the workpiece and machining allowance. In the event the machining sizing is large and also the allowance is large, cemented carbide rotary burr with a large size should be selected, or perhaps a tungsten carbide rotary burr having a small size should be selected instead.
