CTD SF-1 Tree Shape Radius Shape Carbide Burr

CTD SF-1 Tree Shape Radius Shape Carbide Burr

The 18479 CTD SF-1 Tree Shape Radius End Carbide Burr is a double-cut tungsten carbide burr designed for smooth interior contouring and rounded edge work in tight areas. Also known as a rounded tree shape, this burr excels at shaping and blending curved surfaces where precision matters. Made from extremely hard tungsten carbide, it outperforms HSS in demanding applications and maintains cutting performance under higher temperatures—because detail work deserves a tool that holds its edge.
