Hertel H08700999 Indexable Anvil 0.375 Inch Insert

Product Description

The HERTEL H08700999 is an indexable anvil designed to seat and support insert-style cutting tools in compatible toolholders. The anvil provides a stable, precision-ground seating surface that maintains insert positioning under cutting loads, protecting the toolholder pocket from wear and damage. It is sized for a 0.375-inch insert inscribed circle and carries a toolholder insert size code of 16. The helix angle is -1.5 degrees, and the anvil supports both external left-hand and internal right-hand orientations. Machinists and toolroom technicians use this component as a consumable wear part in indexable turning and boring setups.

This anvil is used in metal-cutting applications where indexable inserts are held in toolholder pockets requiring an intermediate seating component. Typical applications include turning, boring, and similar lathe or machining-center operations. The dual orientation designation, external left-hand and internal right-hand, makes this anvil applicable to a range of toolholder configurations. It is a direct replacement-style consumable for any compatible HERTEL indexable toolholder that accepts a size 16 anvil with a 0.375-inch inscribed circle seat.

Compatibility

Designed as an OEM-style replacement anvil for indexable toolholders requiring a size 16 insert seat with a 0.375-inch inscribed circle and a -1.5 degree helix angle in external left-hand or internal right-hand orientation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians as part of routine insert indexing or toolholder maintenance. Ensure the toolholder pocket is clean and free of chips or debris before seating the anvil. Inspect the anvil seating surface for wear or cracking before each insert change. Follow the toolholder manufacturer torque specifications for the clamping screw, as improper clamping can damage the anvil or compromise insert stability.
