Hertel H08700858 Anvil for Indexable Toolholders

Product Description

The HERTEL H08700858 is a precision anvil designed for indexable cutting toolholders. It seats and supports indexable inserts during metal cutting operations, protecting the toolholder pocket from damage and maintaining consistent insert positioning. This anvil is configured for external right-hand and internal left-hand orientations, with a 0.375-inch insert inscribed circle and a 0.5-degree helix angle. It is sized for toolholder insert size code 16. Weighing 0.12 pounds, it is a compact, lightweight component installed by machinists and tool-room technicians during insert change-outs or toolholder rebuilds.

This anvil is suited for use in CNC turning, boring, and threading applications where indexable insert toolholders are in service. It is applicable in both production shop and job-shop environments running external right-hand turning and internal left-hand boring operations. The 16 mm body length makes it compatible with standard-size indexable toolholder pockets that accept a 0.375-inch inscribed circle insert. Machinists replacing worn or damaged anvils during routine insert maintenance will find this a direct-fit service component.

Key Features

• 0.375-inch insert inscribed circle fits standard size-16 indexable insert pockets
• External right-hand and internal left-hand orientation supports common turning and boring configurations
• 0.5-degree helix angle for proper insert seating geometry
• 16 mm body length for precise toolholder pocket fit
• Lightweight at 0.12 pounds for easy handling during insert change-outs

Compatibility

Designed as an OEM-style replacement anvil for indexable toolholders accepting a 0.375-inch inscribed circle insert at size code 16, in external right-hand and internal left-hand configurations.

Installation Notes

Installation is performed by a qualified machinist or tool-room technician. Before replacing the anvil, ensure the machine spindle is fully stopped and locked out per applicable lockout/tagout procedures. Remove the existing insert and clamping screw before extracting the worn anvil, and inspect the toolholder pocket for debris or damage before seating the new anvil. Do not force the anvil into the pocket; proper fitment should require only finger pressure or light hand-tool assistance.
