How To Opt For The Best Carbide Burrs?

Carbide burrs, often known as 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 other industries. Choosing the right carbide burr on your project is crucial. There are many means of selecting a high-quality tungsten carbide rotary burr.

Shapes of tungsten carbide rotary burrs
The shape of the carbide rotary burr must be driven by the shape with 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 needs to be selected; when processing the interior right angle surface, a set burr and square burr might be selected. Once the flat burr is utilized to reduce the inner right angle surface, it is crucial to produce a narrow surface (smooth edge) without teeth near to one of several inner right angle surfaces, in order to avoid damaging the right 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 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 needs to be selected. When used, it should be chosen based on machining allowance, dimensional accuracy, and surface roughness needed by the workpiece.

Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr should be selected according to the height and width of the workpiece and machining allowance. In the event the machining size is large as well as the allowance is large, cemented carbide rotary burr having a large size must be selected, or a tungsten carbide rotary burr using a small size ought to be selected instead.
