Hertel 1000049 Lh Stgc Indexable Turning Toolholder

Product Description

The HERTEL 1000049 is a left-hand STGC-style indexable turning toolholder designed for external turning operations on CNC lathes and manual turning centers. Built to accept TC..32.5. series inserts secured by a screw-clamp holding method, this toolholder delivers consistent insert repeatability and rigid seating during metal removal. The steel shank measures 0.625 inches wide by 0.625 inches tall with an overall length of 4 inches. A neutral rake angle of 0 degrees suits a broad range of workpiece materials and cutting conditions. Licensed machinists and toolroom technicians handling production turning work are the primary installers.

This toolholder is intended for use in external turning applications where a left-hand cutting direction is required. The 3-degree lead angle and 0.750-inch head length position the insert for controlled chip flow and consistent depth-of-cut engagement. It is well suited for finishing and light roughing passes on bar stock or chucked workpieces in both job-shop and production environments. Coolant-through capability is not available on this holder, so flood or mist coolant delivery must be applied externally at the cutting zone.

Compatibility

Designed to accept TC..32.5. series indexable inserts (complete insert compatibility reference: TC.. 3252). Verify insert geometry and chipbreaker selection against the specific workpiece material and operation before installation.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a full stop, spindle off, and all stored energy released per the machine tool manufacturer lockout procedure. Secure the toolholder in the turret or tool post to the torque specification listed in the machine or toolpost manufacturer documentation. Use the correct Torx or hex key for the insert clamping screw and do not overtighten, as this can fracture the insert or damage the clamp seat. Inspect the insert pocket and seating surface for chips or debris before each insert change.
