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 trusted in machinery, automobile, shipbuilding, chemical industry, craft carving, along with other industries. Selecting the most appropriate carbide burr to your project is of great importance. 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 driven by the shape in the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) must be used; when processing the interior corner surface, triangular burrs should be selected; when processing the interior right angle surface, an appartment burr and square burr could be selected. Once the flat burr is used to cut the interior right angle surface, it’s important to make a narrow surface (smooth edge) without teeth near to one of many inner right angle surfaces, so as to avoid damaging the right angle surface.
Tooth thickness of carbide rotary burrs
The thickness of burr teeth needs to be determined in accordance with the allowance size 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 needs 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 size and style and specification of cemented carbide rotary burr must be selected based on the size of the workpiece and machining allowance. If the machining dimensions are large and the allowance is big, cemented carbide rotary burr having a large size needs to be selected, or possibly a tungsten carbide rotary burr with a small size must be selected instead.
