DCMT11T304MV VP15TF PVD Coated Carbide Turning Insert with MV Chipbreaker and R0.4 Corner Radius for CNC Turning

The DCMT11T304MV VP15TF is premium multilayer PVD-coated carbide indexable turning insert for CNC outer diameter and inner bore rough & semi-finish turning. It adopts 55° rhombic DCMT geometry, MV dedicated chipbreaker design and VP15TF exclusive fine-grain carbide grade, delivering balanced wear resistance and impact toughness to keep stable cutting performance under continuous and moderate interrupted turning conditions.

Optimized MV chip groove ensures regular chip curling and smooth chip removal, securing precise dimensional accuracy and prolonged service life for mass mechanical parts production on CNC lathes and automatic turning equipment.

• VP15TF fine-grain tungsten carbide substrate with advanced PVD coating owns excellent high-temperature oxidation resistance and abrasion resistance, ideal for stainless steel, carbon steel and alloy steel cutting.
