PVD Coated Carbide Turning Insert for Precision Finishing and Shallow Grooving in CNC Machining

The DSCF1612 is premium multilayer PVD-coated carbide indexable turning insert manufactured by TC for CNC outer diameter finishing and shallow grooving applications. With exclusive special DSCF forming geometry and TC fine-grain carbide substrate, the insert combines excellent wear resistance and cutting edge toughness to maintain consistent cutting stability during continuous and mild interrupted finish turning and grooving operations.

Optimized edge and chipbreaker construction delivers controllable chip curling and smooth chip evacuation, securing tight dimensional tolerance and extended service life for mass precision component production on CNC lathes and automatic turning equipment.

• Fine-grain tungsten carbide base with multilayer PVD coating balances high-temperature wear resistance and thermal stability, suitable for finish machining of carbon steel, alloy steel and austenitic stainless steel.
• Custom DSCF profiling cutting edge optimizes surface finish for fine turning and shallow grooving processes.
• Standard DSCF1612 overall dimension with rational clearance angle, easy clamping and stable mounting on matched dedicated DSCF-series tool holders.
• Precision-ground cutting edge achieves superior workpiece surface quality and minimizes burr formation after machining.
• Reinforced edge structure effectively restrains built-up edge accumulation during long continuous production runs and prolongs insert service life.
