The highly versatile Mini-Shaft™ consists of inserts and holders providing stable, high-precision internal threading operations. Mini-Shaft features a special double-serrated joint that creates a secure connection point for its exchangeable inserts and toolholders, resulting in a repeatability of +/- 0.02 mm ( +/- .0008 inch). All toolholders can accommodate R- and L-handed inserts and have through-coolant possibility. Possible for use in holes as small as 8 mm ( 0.315 inch).
