PVD Coated Carbide Turning Insert for Precision Finishing and Light Grooving in CNC Stainless Steel and Carbon Steel Machining

The DSCF1446 is premium multilayer PVD-coated carbide indexable turning insert manufactured by TC for CNC outer diameter and grooving & finishing turning operations. Adopting dedicated DSCF special forming geometry and TC exclusive mature carbide substrate, this insert features outstanding wear resistance and excellent edge toughness to keep stable cutting performance in continuous and mild interrupted finish turning and grooving processes.

Specially optimized groove structure achieves orderly chip curling and smooth chip removal, ensuring stable dimensional precision and longer service life for mass precision component production on CNC lathes and automatic turning equipment.

• Fine-grain tungsten carbide substrate with multilayer PVD coating balances high abrasion resistance and high-temperature stability, suitable for high-speed finish cutting of carbon steel, alloy steel and stainless steel.
• Exclusive DSCF special cutting edge contour optimizes surface finish for finishing and shallow grooving application.
• Standard DSCF1446 fixed overall dimension with reasonable clearance angle, convenient clamping and stable installation on matched dedicated DSCF series tool holders.
• Precision-ground sharp cutting edge delivers ultra-smooth workpiece surface and effectively reduces burr generation after machining.
• Reinforced edge design inhibits built-up edge adhesion during long-cycle continuous production and extends insert service lifespan obviously.
