Tool-flo 916064401 Threading Toolholder 1x1 Inch Shank

Product Description

The TOOL-FLO 916064401 is an external, right-hand indexable threading toolholder designed for precision thread-cutting and grooving operations on CNC lathes and manual turning centers. Built in the Laydown series with an AL toolholder style, it accepts 22ER inserts with a 0.5-inch inscribed circle. The shank measures 1 inch wide by 1 inch tall, and the overall length is 6 inches. Insert retention is handled by a screw-lock clamp for secure, repeatable positioning during interrupted or continuous threading cuts. Licensed machinists and CNC operators install this holder for high-volume external threading work.

This toolholder is suited for external threading and grooving applications in production and job-shop environments. The right-hand orientation is standard for conventional OD turning on most lathe configurations. The Laydown insert geometry positions the 22ER threading insert at the correct rake and clearance angles for consistent thread form. With a head length of 1.42 inches and a back-of-bar to cutting-edge distance of 1 inch, it provides adequate clearance for a range of workpiece diameters. No internal coolant delivery is incorporated, making it straightforward to set up on machines without high-pressure coolant systems.

Compatibility

Designed for use with 22ER series indexable threading inserts with a 0.5-inch inscribed circle. Fits lathe tool posts and turrets accepting a 1 x 1 inch square shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before mounting or indexing inserts. Seat the shank fully in the tool post or turret pocket and torque the clamping bolts to the machine manufacturer's specification. Verify insert seating and thread form with a trial pass at reduced feed before running full production parameters.
