The Best Way To Select The Perfect Carbide Burrs?

Carbide burrs, also known as carbide rotary burrs are 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, and other industries. Selecting the most appropriate carbide burr to your project is important. There are numerous strategies to choosing a high-quality tungsten carbide rotary burr.

Shapes of tungsten carbide rotary burrs
The shape from the carbide rotary burr ought to be based on the design of the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) needs to be used; when processing the inner corner surface, triangular burrs needs to be selected; when processing the interior right angle surface, an appartment burr and square burr might be selected. If the flat burr is utilized to reduce the inner right angle surface, it is necessary to make a narrow surface (smooth edge) without teeth near to one of several inner right angle surfaces, so as to avoid damaging the correct 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 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 ought to be selected. When used, it needs to be chosen based on machining allowance, dimensional accuracy, and surface roughness required by the workpiece.

Sizes of carbide burrs
The scale and specification of cemented carbide rotary burr needs to be selected in accordance with the sized the workpiece and machining allowance. Once the machining dimensions are large as well as the allowance is large, cemented carbide rotary burr having a large size ought to be selected, or even a tungsten carbide rotary burr which has a small size must be selected instead.
