Sandvik Coromant 8019504 Turning Insert Dpmt-pm Carbide

Product Description

The SANDVIK COROMANT 8019504 is a DPMT-style indexable turning insert designed for precision metal removal on CNC lathes and turning centers. Built from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert delivers hardness and thermal resistance suited for continuous and interrupted cuts on steel workpieces. The insert features a 0.375 inch inscribed circle, a 0.0156 inch corner radius, and a PM chip breaker geometry. Neutral hand orientation means it can be applied in either direction of feed. Licensed machinists and CNC operators install these inserts as indexed or replaced cutting edges on standard turning toolholders.

This insert is intended for steel cutting applications, with a secondary suitability for cast iron and similar K-category materials as indicated by the manufacturer grade 4425 classification. It fits toolholders designed for DPMT-series inserts with clamp or screw holding methods. The PM chip breaker geometry is optimized for medium-depth finishing and semi-finishing passes on steel components in both production shop and job-shop environments. The ISO code for this insert is DPMT 11 T3 04-PM 4425.

Key Features

• CVD-applied TiCN, Al2O3, and TiN multilayer coating for elevated wear and heat resistance
• 0.375 inch inscribed circle with 0.0156 inch corner radius for controlled surface finish
• PM chip breaker geometry suited for semi-finishing and medium-depth steel turning
• Neutral hand orientation compatible with both left-hand and right-hand feed directions
• Clamp and screw holding method compatibility for secure insert retention
• Manufacturer grade 4425 targets primary steel cutting with secondary cast iron capability

Compatibility

Designed as an OEM-style replacement turning insert for DPMT-series toolholders accepting a D-shape insert with P clearance and M tolerance class, using clamp or screw holding. Verify toolholder pocket specifications against ISO code DPMT 11 T3 04-PM 4425 before ordering.

Installation Notes

Indexable turning inserts are installed and replaced by licensed machinists or trained CNC operators. Power down and lock out the machine spindle before accessing the toolholder pocket. Seat the insert fully into the pocket and secure with the appropriate clamp or screw torque as specified by the toolholder manufacturer. Inspect the seating surface for chips or debris before each insert change to prevent insert rocking and premature edge failure.
