CTD SL-1 Taper Shape Radius Carbide Burr

CTD SL-1 Taper Shape Radius Carbide Burr

The 019189 CTD SL-1 Taper Shape Radius Carbide Burr is a double-cut tungsten carbide burr designed for precise contouring, surface machining, and rounded edge processing in tight spaces. Also known as a conical ball nose burr, this taper shape excels in narrow workpiece contours and detailed surface blending. Made from extremely hard tungsten carbide, it outperforms HSS in demanding applications and maintains cutting performance under higher temperatures—because fine detail work calls for serious durability.
