Hertel 1000087 Neutral Ctcp Indexable Turning Toolholder

Product Description

The HERTEL 1000087 is a neutral-hand CTCP-style indexable turning toolholder designed for use on CNC lathes and manual turning centers in production and job-shop machining environments. It features a 3-degree positive rake angle and a clamp-type insert holding method, accepting TP..43. series inserts with a 1/2-inch inscribed circle. The shank measures 3/4 inch wide by 1 inch tall with an overall length of 8 inches, making it suitable for standard tool block and turret mounting. Constructed from steel, this toolholder delivers the rigidity required for consistent insert indexing and repeatable cuts across medium to high-volume turning operations.

This toolholder is intended for turning applications where a neutral cutting orientation is required, allowing the tool to feed in either direction or machine to a shoulder. The 3-degree positive rake geometry reduces cutting forces and is well-suited for finishing and semi-finishing passes on ferrous and non-ferrous materials. Machinists, CNC operators, and toolroom technicians working in general-purpose turning will find this holder fits standard CTCP clamp-type tool block configurations. No coolant-through capability is present, so external coolant delivery should be planned accordingly.

Key Features

• Neutral hand orientation allows bidirectional feeding and shoulder-approach turning
• 3-degree positive rake angle reduces cutting forces for finishing and semi-finishing work
• Clamp-type insert holding accepts TP..43. series inserts with 1/2-inch inscribed circle
• Steel construction provides rigidity and durability for production turning environments
• 3/4 inch x 1 inch shank cross-section fits standard CTCP turret and tool block seats
• 8-inch overall length suits typical lathe tool post reach requirements

Compatibility

Compatible with TP..43. series turning inserts, specifically complete insert compatibility designation TP.. 432 with a 1/2-inch inscribed circle. Designed for use in standard CTCP clamp-type toolholder seats on CNC and manual lathes accepting a 3/4 inch x 1 inch shank profile.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the lathe is powered down, the spindle is locked, and the turret or tool post is fully de-energized before mounting or removing toolholders. Verify shank seating and clamp torque per machine manufacturer guidelines before initiating a cut. Confirm insert seating and clamp screw engagement before running the program.
