Sandvik Coromant 8019479 Turning Insert Diamond Carbide

Product Description

The SANDVIK COROMANT 8019479 is a CPMT-series turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. This single insert carries ISO designation CPMT 06 02 04-PF 4425 and features an 80-degree diamond shape (Insert Shape Code C) with a neutral hand orientation. The 4425 grade substrate is solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, providing wear resistance and thermal stability during steel cutting. The PF chip breaker geometry controls chip flow in light-to-medium finishing passes. Corner radius is 0.0156 inches and insert thickness is 0.0938 inches.

This insert is intended for turning steel workpieces in production and job-shop environments where consistent surface finish and tool life are priorities. The secondary workpiece material code K indicates suitability for cast iron as well. The PF chip breaker is optimized for finishing operations at moderate feed rates, making this insert a common choice for machinists running tight-tolerance external or internal diameter cuts on steel components. It is held in place by clamp or screw-type toolholders accepting CPMT-style inserts.

Key Features

• 80-degree diamond insert shape provides a strong cutting edge with good approach angle flexibility
• CVD multilayer TiCN, Al2O3, and TiN coating delivers wear and crater resistance in steel cutting
• PF chip breaker geometry suited for finishing and light-to-medium turning passes
• 0.0156-inch corner radius supports fine surface finish requirements
• Neutral hand orientation fits both right-hand and left-hand toolholder setups
• Clamp and screw holding compatibility provides secure seating in standard CPMT toolholders

Compatibility

Designed for use in CPMT-style clamp or screw-type toolholders accepting an 80-degree diamond insert with clearance code P and tolerance code M, per ISO CPMT 06 02 04 specifications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Seat the insert fully against the toolholder pocket and tighten the clamp or screw to the toolholder manufacturer's specified torque. Inspect the insert seat and shim for debris or damage before installation to prevent insert rocking or premature edge failure.
