Carbide burrs, also called 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, as well as other industries. Choosing the right carbide burr to your project is crucial. There are several means of deciding on a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The form of the carbide rotary burr must be based on the design with the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs should be selected; when processing the inner right angle surface, a flat burr and square burr can be selected. If the flat burr is utilized to slice the interior right angle surface, it is necessary to make a narrow surface (smooth edge) without teeth all-around among the 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 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 should be selected. When used, it ought to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness essential for workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr ought to be selected according to the height and width of the workpiece and machining allowance. Once the machining sizing is large and also the allowance is big, cemented carbide rotary burr having a large size must be selected, or possibly a tungsten carbide rotary burr having a small size must be selected instead.
