Sandvik Coromant 8021002 Turning Insert Tpmt 11 03 04-PF 4415

Product Description

The SANDVIK COROMANT 8021002 is a TPMT-series triangular turning insert engineered for precision metal cutting on CNC and manual lathes. This solid carbide insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, providing wear resistance, thermal stability, and edge hardness across a range of cutting conditions. The insert features a 0.0156 inch corner radius, a neutral hand orientation, and a PF chip breaker geometry optimized for controlled chip evacuation. It is held in place via clamp or screw, consistent with standard TPMT toolholders. Machinists and CNC operators in job shops and production environments install this insert for external turning, facing, and light profiling applications on steel workpieces.

The 8021002 insert is designed primarily for turning steel, with a secondary workpiece material classification of K. It is suited for use in both roughing and finishing passes where consistent chip control is required. The TPMT 11 03 04-PF designation indicates a triangular insert shape with a P clearance angle and M tolerance class. This insert fits standard TPMT-compatible toolholders and is commonly used on horizontal and vertical turning centers in industrial machining operations. Minimum order quantity is 10 units; each package contains 1 insert.

Key Features

• CVD-applied TiCN, Al2O3, and TiN multilayer coating for extended tool life on steel
• Triangular insert shape (T) with P clearance angle and M tolerance class
• 0.0156 inch corner radius for controlled surface finish on steel workpieces
• Neutral hand orientation compatible with left- and right-hand toolholders
• PF chip breaker geometry promotes reliable chip control during turning operations
• Clamp and screw holding method for secure seating in TPMT toolholders

Compatibility

Designed for use in standard TPMT-compatible toolholders. Primary workpiece material is steel; secondary workpiece material code is K. ISO code TPMT 11 03 04-PF 4415 confirms direct fitment with toolholders specifying TPMT 11 03 04 insert geometry.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Seat the insert fully against the toolholder pocket and verify clamp or screw torque is applied per the toolholder manufacturer specification. Inspect the insert seat and pocket for debris or damage before each insert change to maintain cutting accuracy and prevent premature edge failure.
