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 widely used in machinery, automobile, shipbuilding, chemical industry, craft carving, and also other industries. Selecting the right carbide burr for your project is important. There are several strategies to picking a high-quality tungsten carbide rotary burr.

Shapes of tungsten carbide rotary burrs
The contour in the carbide rotary burr needs to be based on the form of the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the inner corner surface, triangular burrs should be selected; when processing the inner right angle surface, an appartment burr and square burr could be selected. In the event the flat burr is employed to cut the interior right angle surface, it is crucial to make a narrow surface (smooth edge) without teeth all-around one of many inner right angle surfaces, to be able to avoid damaging the proper angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth should be determined in line with the allowance size the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr is suitable 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 should be selected. When used, it needs to be chosen based on machining allowance, dimensional accuracy, and surface roughness needed by the workpiece.

Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr needs to be selected in accordance with the size of the workpiece and machining allowance. Once the machining dimensions are large and also the allowance is big, cemented carbide rotary burr with a large size should be selected, or possibly a tungsten carbide rotary burr using a small size must be selected instead.
