Engineered with revolutionary chemistry and grain shape, Quantum 3NQP CA surface grinding segments deliver 33 to 100 percent longer life and a 30 percent higher metal removal rate than standard ceramic products, with 15 percent lower threshold power. Featuring a porous VSP vitrified bond, these segments provide increased chip clearance and coolant flow for reduced loading and cool cutting during heat-sensitive work. Pair these segments with your Cortland and Cortland Bonus Grind chucks, and mount them on old or new surface grinding machines to perform low-, medium- and high-force stock removal on irons, super alloys, titanium and other hard-to-grind steels.
