Carbide burrs, also referred to as carbide rotary burrs are widely-used 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, along with other industries. Selecting the right carbide burr to your project is important. There are several options for choosing a high-quality tungsten carbide rotary burr.

Shapes of tungsten carbide rotary burrs
The form in the carbide rotary burr should be based on the form in the workpiece. When processing the inner arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the inner corner surface, triangular burrs needs to be selected; when processing the inner right angle surface, an appartment burr and square burr might be selected. If the flat burr is utilized to slice the inner right angle surface, it is necessary to produce a narrow surface (smooth edge) without teeth near to one of many inner right angle surfaces, in order to avoid damaging the correct angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined based on the allowance size 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 should be chosen based on 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 needs to be selected based on the height and width of the workpiece and machining allowance. In the event the machining sizing is large and the allowance is large, cemented carbide rotary burr using a large size should be selected, or even a tungsten carbide rotary burr which has a small size should be selected instead.
