What are carbide burrs?
Definition
Tungsten Carbide Rotary burrs are also known as high-speed milling cutters and mold milling cutters. It can process a variety of metals, including a variety of hardened steel and non-metal, such as marble, jade bone, etc. It is regarded as an important way to improve production efficiency and realize the mechanization of the fitter.
Application
Deburring, chamfering, milling out for the preparation of build-up welding, machining weld seams, machining contours, cleaning cast material, Trimming, contour milling, cutting out holes
What are carbide burr cuts?
To meet all the different applications, different materials, different levels of processing. FITCARBIDE designed six different tooth shapes for Carbide burrs.
