About This

Useful Double Cut: This is the most classic, commonly used, and widely used cut style among all the Carbide rotary Burrs, files, which can be used for cutting and polishing most materials
Bur head with 91.5HRA: The carbide rotary burs/files are made of high-quality Carbide Bur Head that is 91.5HRA (or78.4 HRC) in hardness, that with very good wear-resistant, and theoretically suitable for machining any metal or non-metal or composite materials below 70HRC
Carbide Bur Head is Solid: The Carbide Bur Head is designed to be solid without a tail hole or center hole (for inserting and fixing the shank), which help the Carbide burrs get higher strength and longer service life
R-Shaped Shank: The shank of the Carbide Burrs Rotary Files is designed in the form of R-shaped, which increases the contact area(joint area) between the Shank and the Carbide Bur Heads, making the welding more secure and strong
Very Strong Welding: the Carbide Burrs Rotary files are welded by imported silver based brazing alloy, with low welding temperature, which make the Joint/welding area between the Carbide bur Head and the shank with very strong, and there is no phenomenon of breaking or falling-off of Carbide Bur head from the shank
