Sandvik Coromant 8019503 Turning Insert Dpmt-pm Carbide

Product Description

The SANDVIK COROMANT 8019503 is a DPMT-PM series turning insert designed for steel machining in roughing and medium machining operations. It carries ISO code DPMT 07 02 08-PM 4425 and is manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. This coating stack provides high wear resistance while maintaining toughness across a range of cutting conditions. The insert features a diamond (rhombic) 55-degree shape, a positive side clearance, and a neutral hand orientation. With a 0.25 inch inscribed circle and a 0.0313 inch corner radius, it is suited to finishing and intermediate-stock-removal passes on steel workpieces. It is installed and indexed by CNC machinists and toolroom technicians using clamp or screw holding methods.

This insert is intended primarily for steel (ISO material group P) applications, with secondary suitability for cast iron (ISO group K) workpieces. The PM chip breaker geometry supports both roughing and medium machining scenarios, making it a versatile choice for production turning on CNC lathes and turning centers. Grade 4425 is characterized by high wear resistance to moderate wear resistance combined with toughness, positioning it for interrupted and continuous cuts in steel components.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life in steel cutting
• Diamond 55-degree insert shape (DPMT) with positive side clearance for reduced cutting forces
• PM chip breaker geometry rated for roughing and medium machining operations
• Neutral hand orientation for flexible toolholder compatibility
• 0.0313 inch corner radius balances surface finish quality and edge strength
• Compatible with clamp and screw insert holding systems

Compatibility

Designed as an OEM-style replacement insert for DPMT-PM series toolholders accepting a DPMT 07 02 08 geometry insert. ANSI insert code DPMT21.52; ISO insert code DPMT070208. Verify toolholder pocket geometry, clamp style, and seat size before installation.

Installation Notes

Insert indexing and replacement should be performed by a qualified CNC machinist or toolroom technician with the machine in a full stop, spindle off, and energy isolated per lockout/tagout procedures. Use the appropriate torque wrench or screwdriver for the clamp or screw holding system specified by the toolholder manufacturer. Inspect the insert pocket and seating surface for debris or wear before seating the new insert. Do not use a damaged or cracked insert.
