VC toolholders deliver high accuracy (runout within 0.00012 in. at 4 3 diameter) and precise finishes, and their slim and smooth profiles lessen noise from high-speed rotation and air current created by hex nuts and slots. Grooves under the nuts dampen micro harmonic vibrations. For more rigidity and static stiffness, these toolholders have short gauge lengths and thicker walls at their bases, and 8° collets contribute to rigidity and gripping torque and let the toolholders operate up to 40,000 rpm.
