How To Choose The Perfect Carbide Burrs?

Carbide burrs, also known as carbide rotary burrs are employed with high-speed electric mills or die grinders to process metal, wood, plastics, etc. Carbide rotary burrs are traditionally used in machinery, automobile, shipbuilding, chemical industry, craft carving, and other industries. Choosing the proper carbide burr to your project is important. There are numerous options for choosing a high-quality tungsten carbide rotary burr.

Shapes of tungsten carbide rotary burrs
The design of the carbide rotary burr must 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 interior corner surface, triangular burrs must be selected; when processing the interior right angle surface, a set burr and square burr could be selected. If the flat burr is utilized to cut the interior right angle surface, it is crucial to produce a narrow surface (smooth edge) without teeth near to among the inner right angle surfaces, in an attempt to avoid damaging the correct angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth should be determined in accordance with the allowance height and width of the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr would work 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 ought to be selected. When used, it needs to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness essential for workpiece.

Sizes of carbide burrs
The size and style and specification of cemented carbide rotary burr ought to be selected based on the size the workpiece and machining allowance. Once the machining dimensions are large along with the allowance is large, cemented carbide rotary burr with a large size must be selected, or a tungsten carbide rotary burr having a small size needs to be selected instead.
