Double the Cut, Double your Output
Designed to work as long as you do, Norton double-cut carbide burrs withstand the most demanding production runs due to the hardness of their tungsten carbide substrate, plus their stronger tooth formulation. Get ready to achieve better stock removal and granular chip break when you pair these carbide burrs with our Norton pneumatic die grinder or use them in your automated CNC machine.
