Sandvik Coromant 8020997 Turning Insert Dpmt-pm 0.375 in Ic

Product Description

The SANDVIK COROMANT 8020997 is a DPMT-series turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which delivers wear resistance and thermal stability across a range of workpiece materials. The insert features a 0.375-inch inscribed circle, a 0.0313-inch corner radius, and a 0.1563-inch insert thickness. The neutral hand orientation makes it suitable for both right-hand and left-hand toolholders. It is held in place by either clamp or screw mounting methods and is intended for use by machinists and tooling technicians in production and job-shop environments.

This insert is suited for turning operations on cast iron and similar materials classified under ISO workpiece material code K. The DPMT 11 T3 08-PM 4415 falls within the DPMT-PM series, which is designed for general-purpose turning with positive-geometry toolholders. The PM chip breaker geometry supports controlled chip evacuation during continuous and light-interrupted cuts. It is commonly used in residential machine shops, production facilities, and contract manufacturing operations where consistent tool life and surface finish are required.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended wear resistance and thermal protection
• 0.375-inch inscribed circle with 0.0313-inch corner radius for precise finish geometry
• Neutral hand orientation — compatible with both right-hand and left-hand toolholders
• Clamp or screw holding method for secure, repeatable seating in standard toolholders
• PM chip breaker geometry supports reliable chip control on ISO K workpiece materials
• 11-degree relief angle with DPMT insert shape for positive-rake cutting action

Compatibility

Designed as an OEM-style replacement turning insert for DPMT-style positive toolholders accepting a 0.375-inch inscribed circle insert with clamp or screw holding. Refer to the DPMT-PM series toolholder specifications to confirm pocket and seating compatibility before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or tooling technician with the machine fully powered down and the spindle locked. Use the appropriate torx or hex key to tighten clamp or screw hardware to the toolholder manufacturer's specified torque. Inspect the insert pocket and seating surface for chips or debris before seating the insert to ensure full contact. Follow your facility's tooling change procedures and applicable shop safety standards when handling cutting inserts.
