Tool-flo 916064361 Threading Toolholder 1x1 Inch Shank

Product Description

The TOOL-FLO 916064361 is an external, right-hand indexable threading toolholder designed for precision thread-cutting operations on CNC lathes and manual turning centers. Built in the Laydown series with an AL toolholder style, it accepts 16ER inserts with a 0.375-inch inscribed circle and uses a screw-clamp holding method for secure, repeatable insert positioning. The shank measures 1 inch wide by 1 inch tall and 6 inches in overall length. This toolholder weighs 1 pound and is rated for both grooving and threading applications, making it a versatile choice for shops running a range of external thread profiles.

This toolholder is suited for external threading and grooving operations in production and job-shop environments. The right-hand configuration is standard for conventional lathe setups where the tool feeds from right to left. The 1 x 1 inch shank fits common square-shank tool blocks and quick-change turret positions found on most production turning centers. No coolant-through capability is present on this holder, so flood or mist coolant must be directed externally at the cutting zone.

Compatibility

Designed to accept 16ER indexable threading inserts with a 0.375-inch (3/8 inch) inscribed circle. Fits standard 1 x 1 inch square-shank tool blocks and turret stations on CNC and manual turning centers.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Power down and lock out the machine spindle before changing or indexing inserts. Seat the shank fully into the tool block and torque the clamping screws evenly to the machine manufacturer's specification before taking any cut. Verify insert seating and shim stack before running the first thread pass.
