Design features of Type E carbide rotary files

The head of Type E carbide rotary file is oval in shape, which can be better adapted to different machining surfaces and shapes to meet more flexible cutting needs, for example, in the machining of mold cavities, it is easier to access some narrow or curved parts.

There are various sizes of cutting edge diameters, such as the common e0610 (6mm cutting edge), e0813 (8mm cutting edge), e1016 (10mm cutting edge), e1220 (12mm cutting edge), etc. to meet different machining needs. The smaller diameters are suitable for fine machining or handling smaller parts, while the larger diameters can be used to remove large amounts of material more quickly.

Type E tungsten carbide rotary burrs are commonly available with shank diameters of 6mm, etc. The size of the shank needs to be matched to the chuck of the power tool or machine tool being used to ensure that the file can be securely mounted on the equipment to avoid loosening or falling off during high-speed rotation.

Usually the file wheel center open hole, and then let the head of the rotary shaft into the hole, and through the screws will be fixed to connect the two as a whole. This design facilitates the production and replacement of different types of file wheels, and also ensures the overall stability of the rotary file during operation.
