Hertel 1000041 Lh Stgc Indexable Turning Toolholder

Product Description

The HERTEL 1000041 is a left-hand STGC-style indexable turning toolholder designed for precision external turning operations on metal lathes and turning centers. Built on a screw-type insert clamping system with a neutral rake angle of 0 degrees, this toolholder accepts TC..32.5. series inserts secured by a single clamping screw. The shank measures 0.75 inches wide by 0.75 inches tall with an overall length of 4.5 inches. The toolholder body is steel construction, providing rigidity under continuous turning loads. Licensed machinists and CNC lathe operators working in production or job-shop environments are the primary installers.

This toolholder is suited for external turning applications on manual lathes and CNC turning centers where a left-hand cutting direction and neutral rake geometry are required. The 3-degree lead angle and 0.75-inch head length make it practical for shoulder turning and general profiling. The back of bar to cutting edge distance measures 1 inch, which simplifies tool offset entry during setup. Coolant-through capability is not available on this holder, so flood or mist coolant must be applied externally.

Key Features

• Left-hand cutting orientation for STGC-style toolholder configurations
• Neutral rake angle (0 degrees) compatible with a broad range of workpiece materials
• Screw-type insert clamping method for positive, repeatable insert location
• Accepts TC..32.5. inserts with a 3/8-inch inscribed circle
• Steel toolholder body for rigidity under interrupted and continuous cutting loads
• 0.75 inches x 0.75 inches square shank fits standard lathe tool posts and turrets

Compatibility

Designed for use with TC..32.5. series indexable inserts (complete insert compatibility: TC.. 3252). Fits standard lathe tool posts and quick-change turrets accepting a 0.75-inch square shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the lathe spindle before seating or changing inserts and before mounting the toolholder in the turret or tool post. Torque the insert clamping screw with the appropriate Torx or hex key supplied or specified by the insert manufacturer. Verify tool centerline height against the spindle centerline before taking the first cut, as incorrect height will affect surface finish and tool life.
