Sandvik Coromant 8019499 Turning Insert Cpmt-pm 4425

Product Description

The SANDVIK COROMANT 8019499 is a CPMT-PM series solid carbide turning insert designed for precision metal cutting operations on CNC lathes and turning centers. Identified by ISO code CPMT 06 02 08-PM 4425, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN that provides heat resistance and wear protection during continuous and interrupted cuts. The inscribed circle measures 0.25 inches and the corner radius is 0.0313 inches, making it suited to finish and semi-finish turning passes. Insert thickness is 0.0938 inches. Grade 4425 is optimized for steel applications and delivers reliable tool life across a range of cutting parameters. This insert is installed by machinists and CNC operators in production and job-shop environments.

The 8019499 is used in steel turning applications, classified under primary workpiece material Steel with a secondary workpiece material code of K, indicating suitability for cast iron as well. The CPMT insert shape code C denotes an 80-degree diamond geometry. The neutral hand orientation makes it usable in both right-hand and left-hand toolholder configurations. The PM chip breaker geometry is engineered for positive chip control across light to medium depths of cut in steel and similar ferrous materials. Typical install scenarios include finish turning of shafts, flanges, and bores in both low-volume and high-volume production settings.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended wear resistance and thermal protection
• Grade 4425 carbide substrate optimized for steel turning
• CPMT-PM chip breaker geometry for controlled chip evacuation in light to medium cuts
• Neutral hand orientation compatible with right-hand and left-hand toolholders
• 0.0313-inch corner radius suitable for finish and semi-finish turning passes
• Clamp and screw holding method for secure seating in standard CPMT-style pockets

Compatibility

Designed for use in toolholders with CPMT-style insert pockets that accept an 80-degree diamond (shape code C) insert with a P clearance angle and M tolerance. Compatible with standard clamp and screw holding systems. Specific toolholder compatibility should be verified against the holder manufacturer pocket specification prior to installation.

Installation Notes

This insert is installed by qualified machinists or CNC operators and does not require any trade license, but proper toolholder selection and pocket condition should be confirmed before seating the insert. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and screw type specified by the toolholder manufacturer when securing the clamp or clamping screw. Inspect the insert pocket for chips or debris that could prevent full seating and cause premature insert failure.
