Hertel H59873133 Boring Insert Diamond 80 Deg Solid Carbide

Product Description

The HERTEL H59873133 is a solid carbide boring insert designed for precision internal boring operations on CNC and manual turning equipment. Formed in an 80-degree diamond shape, it carries an inscribed circle of 5/32 inch (0.1563 inch), a corner radius of 0.007 inch, and a thickness of 0.040 inch. The 15-degree relief angle reduces cutting forces during fine finishing passes. Uncoated solid carbide construction at material grade C1 delivers consistent dimensional accuracy in applications where coating buildup would compromise tolerances. Screw-in holding method provides positive clamping and repeatable indexing. This insert is sized and configured for toolholders and boring bars that accept CDHH-style inserts.

This insert is suited for finish and semi-finish boring in ferrous and non-ferrous materials where tight tolerances and fine surface finishes are required. It is commonly used in job-shop and production environments on CNC lathes and boring mills. The right-hand cutting orientation makes it compatible with standard right-hand boring bar setups. Machinists, CNC operators, and toolroom technicians working on precision bores will find the 80-degree diamond geometry effective for reaching into confined bore profiles with minimal tool pressure.

Key Features

• 80-degree diamond shape (CDHH insert style) for precise boring geometry
• Solid carbide construction, material grade C1, uncoated finish
• 5/32 inch inscribed circle (0.1563 inch) for compact boring bar compatibility
• 0.007 inch corner radius supports fine finishing and sharp profile transitions
• 15-degree relief angle reduces cutting forces and tool deflection
• Screw-in holding method ensures positive, repeatable insert seating
• Right-hand cutting orientation for standard boring bar configurations

Compatibility

Designed for use in CDHH-style boring bars and toolholders that accept an 80-degree diamond insert with a 5/32 inch inscribed circle and screw-in clamping. Confirm toolholder insert pocket specifications before ordering.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before indexing or replacing inserts. Use the correct screw torque driver recommended by the toolholder manufacturer to seat the insert without cracking the carbide body. Inspect the insert pocket for chips or debris before seating a new insert to maintain proper clamping and dimensional repeatability.
