● TCT cutters offer tapered head to accommodate NPT and NPTF style inserts

● TCN cutters offer straight head to accommodate UN and ISO style inserts

● Inserts are CNC ground to tolerance of +/-.0005 effective in the cutter

● Positive geometry provides high shear action which results in better quality threads

● Cutters feature our patented locking system for accurate indexes



● Design allows for maximum number of flutes in minimum part diameter

● Cutters feature our patented locking system for accurate indexes



● Design allows for maximum number of flutes in minimum part diameter

● Run at high speeds to reduce machining time by as much as 50%
