Hertel 1000176 Mtfn Indexable Turning Toolholder

Product Description

The HERTEL 1000176 is a right-hand MTFN-style indexable turning toolholder designed for use with TN..43. series inserts on metal-cutting lathes and turning centers. Built from steel with a 1 inch by 1 inch square shank and an overall length of 6 inches, this toolholder accommodates negative rake geometry at a -5-degree rake angle. It uses a clamp and screw insert-holding method that keeps the insert securely seated during heavy interrupted or continuous cuts. Licensed machinists and CNC lathe operators working in production or job-shop environments will find this a practical, straightforward replacement or spare in the turning tool lineup.

This toolholder is suited for external turning operations on manual and CNC lathes in both production and job-shop settings. The MTFN style positions the insert for side-cutting applications, and the right-hand designation means cutting action moves from right to left toward the chuck. It is compatible with TN..43. series inserts, specifically TN.. 432, with a 1/2-inch inscribed circle. The back-of-bar to cutting-edge dimension measures 1.25 inches, and the head length is 1.22 inches, making it a direct fit for standard square-shank tool blocks and quick-change turrets sized for 1 inch shanks.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine before seating or changing the toolholder or insert. Ensure the shank seating surfaces in the tool block are clean and free of chips before clamping. Do not exceed the machine tool manufacturer's recommended clamping torque for the tool block screws.
