CNMG120408MS PR1535 (TLC50922)

The CNMG120408MS PR1535 is a versatile indexable turning insert engineered for medium turning and semi-roughing of steel and stainless steel. The PVD-coated PR1535 carbide grade provides excellent toughness for interrupted cuts and unstable conditions, while the MS chipbreaker geometry delivers consistent chip control across a broad range of feeds and depths of cut. The uniform dark PVD coating visible on the rake face ensures low friction and resistance to built-up edge.

Key Features

• Insert shape: C (80° diamond) — 2 cutting edges per insert
• Size: 12mm x 04mm thickness x 08 nose radius (0.8mm)
• Chipbreaker: MS — medium turning geometry, reliable chip breaking at medium feeds and depths
• Grade: PR1535 (PVD-coated carbide) — high toughness, excellent for interrupted cuts and difficult conditions in steel
• ISO application: P20–P40, M20–M35
• Edges: 2 cutting edges

Applications

External and internal turning, facing, and boring of carbon steel, alloy steel, and stainless steel in medium to rough cutting conditions. An excellent general-purpose choice where toughness and chip control are both required. Compatible with CNMG-style toolholders. Available in packs of 10.
