Tool-flo 96001256 Indexable Threading Toolholder

Product Description

The TOOL-FLO 96001256 is an external, right-hand indexable threading toolholder designed for precision thread-cutting and grooving operations on CNC lathes and turning centers. Built in the On-Edge series with a MTVO toolholder style, it accepts T.MA/C 43 inserts with a 0.5-inch inscribed circle. The shank measures 0.75 inches wide by 0.75 inches tall and the overall length is 4.5 inches. Insert holding is achieved through a clamp-and-pin method, providing positive, repeatable positioning during high-feed threading passes. This toolholder is installed by machinists and CNC setup technicians in production and job-shop environments.

The 96001256 is suited for external threading and grooving applications on ferrous and non-ferrous workpieces. The 0.75 x 0.75 inch shank fits standard OD turning tool blocks and quick-change toolposts commonly found on small to mid-size CNC lathes. With a head length of 1.23 inches and a maximum depth of cut of 0.23 inches, it handles typical threading operations where reach and rigidity are both priorities. This toolholder does not include through-coolant capability; coolant must be directed externally if required by the application.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before mounting or indexing inserts, power down the machine and engage all axis locks per shop safety procedure. Torque the clamp and pin hardware according to the insert manufacturer guidelines using calibrated tooling. Confirm tool offset and runout after mounting before initiating any cutting cycle.
