How To Choose The Best Carbide Burrs?

Carbide burrs, often known 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, as well as other industries. Selecting the right carbide burr to your project is of great importance. 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 should be based on the form in the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the interior corner surface, triangular burrs must be selected; when processing the interior right angle surface, an appartment burr and square burr might be selected. In the event the flat burr is utilized to reduce the interior right angle surface, it is necessary to make a narrow surface (smooth edge) without teeth close to one of many inner right angle surfaces, so as to avoid damaging the correct angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined in line with the allowance height and width of the workpiece, machining accuracy, and material properties. The coarse tooth carbide burr is acceptable 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 should be chosen based on machining allowance, dimensional accuracy, and surface roughness required by the workpiece.

Sizes of carbide burrs
The dimensions and specification of cemented carbide rotary burr should be selected in accordance with the size of the workpiece and machining allowance. If the machining size is large as well as the allowance is big, cemented carbide rotary burr using a large size needs to be selected, or possibly a tungsten carbide rotary burr having a small size needs to be selected instead.
