Hertel 1000133 Msrn Indexable Turning Toolholder 1x1 Shank

Product Description

The HERTEL 1000133 is a right-hand MSRN-style indexable turning toolholder designed for negative-rake turning operations on the lathe. It features a 1 x 1 inch square shank and an overall length of 6 inches, making it a standard-size holder suited for medium to heavy turning work. The holder accepts SN..43. series inserts secured by a clamp and screw holding method, providing rigid, repeatable insert positioning. Machined from steel, this toolholder is built for the rigidity demands of negative-rake cutting geometry. It is installed and used by machinists and toolroom technicians in production and job-shop turning environments.

This toolholder is used in external turning applications on manual and CNC lathes. The 15-degree lead angle and negative-rake geometry make it well suited for general roughing and finishing passes on ferrous and non-ferrous workpieces. The right-hand orientation indicates cutting from right to left toward the chuck. The 1.23 inch head length and 1.13 inch back-of-bar to cutting-edge dimension suit standard tool post and turret setups. It is a single-purpose turning tool, not configured for multi-use or coolant-through operation.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the shank fully in the tool post or turret and confirm the cutting edge height is on center before commencing cuts. Always stop the machine spindle and lock out the lathe before changing inserts or adjusting the holder. Follow the insert manufacturer torque guidance when tightening the clamp screw to avoid insert seat damage.
