Tool-flo 93401208B Threading Toolholder 0.75 Inch Shank

Product Description

The TOOL-FLO 93401208B is an external, right-hand indexable threading toolholder in the FLSR series, designed for precision thread cutting and grooving on CNC lathes and turning centers. The holder accepts FL 2R inserts secured by a clamp-style holding method, providing reliable insert retention during interrupted cuts and continuous threading passes. The 0.75 x 0.75 inch square shank and 4.5 inch overall length suit a wide range of turret and block-style tool stations. With a maximum depth of cut of 0.14 inches and a back-of-bar to cutting edge distance of 1.0 inch, this holder is built for controlled, repeatable external threading operations performed by machinists and CNC operators in production and job-shop environments.

This toolholder is suited for external threading and grooving applications on ferrous and non-ferrous workpieces. The FLSR series design fits standard square-shank tool stations and is appropriate for both high-volume production runs and short-run precision work. It is configured without coolant-through capability, making it compatible with conventional flood or mist coolant delivery setups. The multi-use designation means this holder can serve both threading and grooving operations, reducing the number of dedicated holders required in the setup.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret is in a safe indexed position before mounting or removing the toolholder. Torque all mounting fasteners according to the machine tool manufacturer's specifications for the turret or tool block in use. Verify insert seating and clamp engagement before initiating any cutting cycle.
