Carbide burrs
From GAWDAwiki
Carbide burrs, which are also known as rotary files, consist of small and large shaped cutters used in die grinders, rotary tools and dentists' drills. The name may be considered suitable when their mini-size head (3mm diameter shaft) is closely similar to that of a seed in the burr fruit. Carbide burrs are also used in CNC machining robot “type” centers for removing burrs (the small flakes of metal) after a machining process (burrs-cutting, n.d.) To sustain the right external speed and cutting environment they are rotated at the maximum velocity achievable, appropriate with their size and structure.
In engineering, a burr can be described as the raised circumference on metal. It may be present in the form of a fine wire on the edge of a freshly sharpened tool or as a raised portion on a surface, after being struck a blow from an equally hard or heavy object. Specifically, burrs are as a rule useless residual that is the effect after machine grinding, drilling, milling or turning. [1]
