CTD SF-3 Tree Shape Radius Shape Carbide Burr

CTD SF-3 Tree Shape Radius Shape Carbide Burr

The 701504 CTD SF-3 Tree Shape Radius Carbide Burr is a premium double-cut tungsten carbide burr designed for precision contouring, deburring, and material removal in tight spaces. Featuring a rounded tree (radius) head shape and a durable ¼” shank, this burr excels at interior contour work and rounded edge processing. Built from extremely hard tungsten carbide, it outperforms HSS in demanding applications, maintains performance at higher temperatures, and delivers long service life—because your burr should wear out from hard work, not give up early.
