CTD SF-5 Tree Shape Radius Shape Carbide Burr

SF-5 TREE SHAPE - RADIUS PREMIUM TUNGSTEN CARBIDE BURR– ¼” shank

The 701507 SF-5 Tree Shape Radius Premium Tungsten Carbide Burr is a high-performance double-cut carbide burr built for precision contouring, deburring, and material removal in tight spaces. Featuring a rounded tree shape head and 1/4" shank, this burr is ideal for interior contour work and rounded edge processing. Manufactured from extremely hard tungsten carbide, it outperforms HSS in demanding applications and maintains cutting performance even at elevated temperatures. One burr, plenty of capability.
