Tool-flo 93101216B Threading Toolholder 0.75 Inch Shank

Product Description

The TOOL-FLO 93101216B is an indexable threading toolholder designed for external threading and grooving operations on CNC lathes and turning centers. Part of the FLER series, this right-hand holder accepts FL 3L inserts secured by a clamp-style holding method. The shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches. A maximum depth of cut of 0.21 inches and a back-of-bar to cutting edge distance of 1.125 inches make this holder well suited for precise thread-form applications. It is installed and set up by machinists and CNC operators working in production or job-shop environments.

This toolholder is built for external threading and grooving on turned parts in both production and low-volume machining environments. The right-hand orientation is standard for conventional lathe setups. The FLER series design provides a rigid, repeatable platform for threading inserts, reducing setup time when indexing worn inserts. The 4.5-inch overall length fits standard OD turning tool blocks and quick-change toolpost systems commonly found on production lathes.

Installation Notes

This toolholder is installed by machinists following standard OD turning tool setup procedures.
