CTD SD-5 Ball Shape Carbide Burr

CTD SD-5 Ball Shape Carbide Burr

The 701307 CTD SD-5 Ball Shape Carbide Burr is a premium double-cut tungsten carbide burr built for precision deburring, contouring, and material removal in demanding applications. Featuring a 1/2" ball-shaped head and 1/4" shank, this burr excels at interior contour work, bore deburring, and weld prep cleanup. Manufactured from extremely hard tungsten carbide, it delivers longer service life and superior heat resistance compared to HSS—because tough jobs deserve tougher tooling.
