CTD SG-1 Pointed Tree Shape Carbide Burr

CTD SG-1 Pointed Tree Shape Carbide Burr

The 18739 CTD SG-1 Pointed Tree Shape Carbide Burr is a double-cut tungsten carbide burr engineered for precise material removal in tight spaces and sharp contours. Its pointed tree shape makes it ideal for acute angles and detailed work, while the extreme hardness of tungsten carbide delivers longer life and better performance than HSS—especially when the job gets demanding. Designed for use in die grinders and pneumatic hand tools, this burr handles metal, non-metal, and composite materials with confidence and control.
