Hertel H08700791 Anvil for Indexables 0.375 Inch

Product Description

The HERTEL H08700791 is a precision-ground anvil designed for use with indexable insert toolholders. It seats beneath the cutting insert to provide a stable, repeatable support surface that protects the toolholder pocket and maintains insert positioning during machining operations. This anvil features a 0.375 inch insert inscribed circle and a 2.5 degree helix angle. It is sized for a toolholder insert size code 16 and supports dual-orientation installations: External Left Hand and Internal Right Hand configurations. Machinists and toolroom technicians install anvils as consumable components during routine insert changes or when pocket damage requires seat replacement.

This anvil is suited for turning and boring applications where indexable inserts are used in external or internal operations. The dual-orientation designation — External Left Hand and Internal Right Hand — means a single anvil seat geometry serves both cutting directions depending on toolholder configuration. Typical applications include production turning centers and manual lathes running indexable insert toolholders that require a size 16 insert seat. The 0.375 inch inscribed circle matches the seating requirement for inserts in that IC class.

Key Features

• 0.375 inch insert inscribed circle for size 16 toolholder compatibility
• 2.5 degree helix angle machined into the seat geometry
• Dual-orientation: External Left Hand and Internal Right Hand
• Compact form factor at 16 mm seat length for space-constrained pockets
• Consumable replacement seat that preserves toolholder pocket integrity

Compatibility

Designed as an OEM-style replacement anvil for indexable insert toolholders requiring a 0.375 inch inscribed circle seat with a size 16 insert code and a 2.5 degree helix angle.

Installation Notes

Anvil installation is performed by machinists or toolroom technicians during insert indexing or toolholder maintenance. Before removing or installing the anvil, ensure the machine is powered down, the spindle is locked, and all stored energy is relieved. Use the manufacturer-specified torque driver for the anvil retaining screw — do not overtighten, as seat cracking or pocket thread damage can result. Inspect the toolholder pocket for debris or damage before seating the new anvil.
