Carbide burrs, also 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, and also other industries. Choosing the proper carbide burr on your project is essential. There are lots of options for picking a high-quality tungsten carbide rotary burr.
Shapes of tungsten carbide rotary burrs
The contour with the carbide rotary burr needs to be based on the shape from the workpiece. When processing the internal arc surface, a semi-circular burr or round burr (small diameter workpiece) should be used; when processing the inner corner surface, triangular burrs needs to be selected; when processing the interior right angle surface, a set burr and square burr could be selected. In the event the flat burr can be used to slice the interior right angle surface, it is vital to create a narrow surface (smooth edge) without teeth near to one of several 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 must be determined based on the allowance sized 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 needs to be selected. When used, it must be chosen according to machining allowance, dimensional accuracy, and surface roughness necessary for workpiece.
Sizes of carbide burrs
The size and specification of cemented carbide rotary burr should be selected in accordance with the size the workpiece and machining allowance. If the machining dimension is large and also the allowance is large, cemented carbide rotary burr with a large size must be selected, or perhaps a tungsten carbide rotary burr with a small size should be selected instead.
