Toolholders with improved balance

Rego-Fix (www.rego-fix.com) says its Q system of steep-taper and HSK high-speed toolholders have improved balance as a result of a low-distortion hardening process and precision balancing. The steep-taper toolholders are prebalanced to G2.5 at 22,000 rpm, while HSK toolholders reach G2.5 at 25,000 rpm. The toolholders, available in CAT, BT, HSK, TC and ISO versions, are made from case-hardened steel and have taper accuracy to AT3 tolerances with a TIR of 0.0001 in., or better. They can be fine-tune balanced to 42,000 rpm and contain grooves to which balancing rings may be added for additional balancing, if required.
