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 trusted in machinery, automobile, shipbuilding, chemical industry, craft carving, and other industries. Choosing the proper carbide burr for your project is important. There are lots of options for choosing a high-quality tungsten carbide rotary burr.


Shapes of tungsten carbide rotary burrs
The form from the carbide rotary burr needs to be driven by the form from the workpiece. When processing the interior arc surface, a semi-circular burr or round burr (small diameter workpiece) ought to be used; when processing the interior corner surface, triangular burrs ought to be selected; when processing the interior right angle surface, a designated burr and square burr could be selected. When the flat burr is utilized to slice the inner right angle surface, it is crucial to make a narrow surface (smooth edge) without teeth near among the inner right angle surfaces, in order to avoid damaging the correct angle surface.

Tooth thickness of carbide rotary burrs
The thickness of burr teeth must be determined according to 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 must be selected. When used, it ought to be chosen in accordance with machining allowance, dimensional accuracy, and surface roughness essential for workpiece.

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