Carbide burrs, also referred to as carbide rotary burrs are widely-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. Choosing the proper carbide burr for your project is important. There are numerous strategies to choosing a high-quality tungsten carbide rotary burr.

Shapes of tungsten carbide rotary burrs
The design of the carbide rotary burr needs to be dependant on the contour in the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs must be selected; when processing the interior right angle surface, an appartment burr and square burr might be selected. In the event the flat burr is used to cut the inner right angle surface, it’s important to create a narrow surface (smooth edge) without teeth near to one of many inner right angle surfaces, so as to avoid damaging the proper angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth should be determined according to the allowance sized the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr would work 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 needs to be selected. When used, it should be chosen as outlined by machining allowance, dimensional accuracy, and surface roughness essential for workpiece.

Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr needs to be selected in line with the size the workpiece and machining allowance. In the event the machining size is large as well as the allowance is large, cemented carbide rotary burr which has a large size ought to be selected, or perhaps a tungsten carbide rotary burr having a small size ought to be selected instead.
