The Way To Opt For The Perfect Carbide Burrs?

Carbide burrs, also referred to as carbide rotary burrs are utilized 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 proper carbide burr for the project is essential. There are several options for deciding on a high-quality tungsten carbide rotary burr.


Shapes of tungsten carbide rotary burrs
The form in the carbide rotary burr must be determined by the shape 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 inner corner surface, triangular burrs should be selected; when processing the interior right angle surface, a designated burr and square burr may be selected. If the flat burr is utilized to chop the interior right angle surface, it is necessary to create a narrow surface (smooth edge) without teeth near one of several inner right angle surfaces, so as to avoid damaging the right angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined according to the allowance height and width of 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 must be selected. When used, it ought to be chosen as outlined by 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 based on the size of the workpiece and machining allowance. If the machining size is large as well as the allowance is large, cemented carbide rotary burr with a large size should be selected, or a tungsten carbide rotary burr with a small size should be selected instead.
