Carbide burrs, also known as carbide rotary burrs are utilized 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 most appropriate carbide burr on your project is essential. There are several options for picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The design with the carbide rotary burr must be based on the shape in the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) should be used; when processing the interior corner surface, triangular burrs must be selected; when processing the interior right angle surface, a designated burr and square burr could be selected. If the flat burr can be used to chop the interior right angle surface, it is vital to produce a narrow surface (smooth edge) without teeth close 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 must be determined in accordance with 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 needs to be selected. When used, it should be chosen based on machining allowance, dimensional accuracy, and surface roughness required by the workpiece.
Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr ought to be selected in accordance with the size the workpiece and machining allowance. Once the machining dimension is large and also the allowance is big, cemented carbide rotary burr using a large size ought to be selected, or even a tungsten carbide rotary burr with a small size ought to be selected instead.
