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 trusted in machinery, automobile, shipbuilding, chemical industry, craft carving, and other industries. Selecting the right carbide burr on your project is essential. There are lots of means of picking a high-quality tungsten carbide rotary burr.


Shapes of tungsten carbide rotary burrs
The shape in the carbide rotary burr needs to be determined by the contour of the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) needs to be used; when processing the inner corner surface, triangular burrs must be selected; when processing the interior right angle surface, an appartment burr and square burr can be selected. In the event the flat burr is utilized to reduce the interior right angle surface, it is crucial to produce a narrow surface (smooth edge) without teeth near one of many inner right angle surfaces, in order to avoid damaging the best angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined based on 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 must be selected. When used, it must be chosen based on machining allowance, dimensional accuracy, and surface roughness essential for workpiece.

Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr must be selected according to the size the workpiece and machining allowance. In the event the machining dimensions are large and the allowance is large, cemented carbide rotary burr with a large size must be selected, or possibly a tungsten carbide rotary burr which has a small size ought to be selected instead.
