Our holders are pre-balanced G2.5 up to 30,000rpm • Extended Holder Life: With double tempered tool steel construction, reduced centrifugal forces, minimized bore contamination, and minimized chatter, a GS Shrink Fit Toolholder should far outlast a standard end mill holder. • Chip load distributed evenly along cutting edge of tool which results in longer tool life • Short projections are possible because no mechanical clamping devices are used. This results in greater rigidity and resistance to bending. • Since Shrink Fit toolholders have no moving parts they offer the greatest repeatability of any tool holding system on the market
