Sandvik Coromant 8029484 Milling Insert MH20 Carbide

Product Description

The SANDVIK COROMANT 8029484 is a solid carbide milling insert in the MH20 series, designed for high-performance milling of hard materials. It carries a TiAlN coating applied via PVD process, which provides thermal resistance and wear protection during interrupted or continuous cuts in hardened workpieces. The insert is parallelogram-shaped with a positive rake angle of 13 degrees, two cutting edges, and a corner radius of 0.0827 inches. Grade 1010 makes this insert well-suited for demanding material removal applications where tool life and edge stability are critical priorities for machinists and tool-room technicians.

This insert is intended for use in hard material applications, classified under primary workpiece material code H. It fits the MH20 cutter series and uses an M20 chip breaker geometry, which is engineered to manage chip formation in tough, abrasive cutting conditions. The screw-type holding method provides secure seating in compatible milling bodies. It is a single-sided, right-hand insert suitable for precision milling operations in tool rooms, production machining environments, and maintenance shops working with hardened steels and similar materials.

Key Features

• Solid carbide construction with TiAlN PVD coating for extended tool life in hard material milling
• Positive rake angle of 13 degrees for reduced cutting forces
• Corner radius of 0.0827 inches for controlled edge blending and surface finish
• M20 chip breaker geometry optimized for hard and abrasive workpiece materials
• Two cutting edges per insert for cost-effective indexing
• Screw-type insert holding for rigid, repeatable seating in MH20 milling bodies

Compatibility

Designed for use with MH20 series milling cutter bodies. ANSI and ISO code: MH20-080425M-M20 1010. Verify cutter body pocket specifications before installation to confirm proper seating and insert size code 080425 fitment.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine in a locked-out, tagged-out state per applicable machine safety procedures. Use the appropriate torx or hex key to seat the clamping screw to the cutter body manufacturer's specified torque — do not over-torque, as this can fracture the carbide insert. Inspect the insert pocket for debris or damage before seating the new insert. Handle solid carbide inserts carefully to avoid chipping edges prior to use.
