Ingersoll Cutting Tools introduces the T-Micro system specifically designed for the machining of very small internal diameters. The T-Micro system is a 2-piece design, consisting of a sleeve and replaceable carbide inserts. Applications include grooving, profiling, chamfering, face grooving/deep face grooving, threading, and back turning starting at .024" (.6 mm). The inserts feature coolant thru capabilities and are available in grade TT9030, a submicron substrate with PVD-TiAlN coating.

Inside the new T-Micro sleeve design is a locating pin to ensure repeatability when indexing the inserts. This allows operators to return to machining without resetting the tool. The locating pin also allows operators to replace inserts without removing the sleeve from the tool post. The T-Micro sleeve also features an angular clamping design to avoid interference when replacing the insert allowing simplified tool change on Swiss-type and other multi-spindle lathes.  Ingersoll offers this sleeve in many shank sizes .500", .625", .750", and 1.00" also 12 mm, 14 mm, 16 mm, 20 mm, 22 mm, and 25 mm to accommodate all machines.
