Walter 7053841 CNMG120408-NMS WSM10S Turning Insert

Product Description

The WALTER 7053841 is a solid carbide turning insert in the CNMG-NMS series, designated by ISO code CNMG120408-NMS WSM10S. It carries a multilayer PVD coating of TiAlN, Al2O3, and Al, which provides heat resistance and edge durability in demanding cutting applications. The insert features an 80-degree diamond shape, a 0.8 mm corner radius, a negative rake geometry, and a chamfered and honed cutting edge style. Four cutting edges are available per insert. This part is installed by machinists and CNC tooling specialists in turning, facing, and boring operations on lathes and turning centers.

The WALTER 7053841 is engineered primarily for machining stainless steel and superalloys and titanium, where edge toughness and coating adhesion are critical. The NMS chip breaker geometry is suited for medium-cut conditions in these difficult-to-machine material groups. Secondary application includes steel workpieces. Typical install scenarios include production turning on CNC lathes where clamp-and-pin insert holding methods are used with CNMG-compatible toolholders. The insert meets both ANSI and ISO standards under industry standard number CNMG432-NMS WSM10S.

Key Features

• Multilayer PVD coating: TiAlN, Al2O3, and Al for heat and wear resistance in stainless steel and titanium cutting
• 80-degree diamond insert shape with negative rake for strength at the cutting edge
• Four usable cutting edges per insert for extended tool economy
• NMS chip breaker designed for medium-cut conditions on stainless steel, superalloys, and titanium
• Chamfered and honed cutting edge for balanced edge strength and sharpness
• Compatible with clamp and pin insert holding methods in standard CNMG toolholders

Compatibility

Designed for use in CNMG-style toolholders that accept clamp and pin holding methods. Suitable for turning, facing, and boring operations on stainless steel, superalloys, titanium, and steel workpieces. Verify toolholder bore and clamp configuration before installation.

Installation Notes

Insert seating and clamping should be performed with the machine fully de-energized and the spindle locked. Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure when securing the clamp and pin. Inspect the insert pocket seat for chips or debris before seating the insert, as contamination affects runout and edge life. Always confirm insert orientation matches the required cutting direction before resuming operation.
