Walter 8115741 Turning Insert DNMG431-FP5 WPP10G Carbide

Product Description

The WALTER 8115741 is a solid carbide turning insert designed for precision metal removal in CNC and manual turning applications. Designated DNMG431-FP5 WPP10G, this insert features a 55-degree diamond shape with a negative rake angle and a chamfered and honed cutting edge for stable, controlled cuts. The multilayer CVD coating - TiCN, Al2O3, and TiN applied in sequence - provides heat resistance and wear protection suited to high-output production environments. The FP5 chip breaker geometry manages chip flow across a range of feed rates and depths. Four usable cutting edges per insert support efficient tooling cost management. Licensed machinists and CNC setup technicians are the primary installers.

This insert is engineered for primary use on steel workpieces (ISO material group P, grade P10) and secondary use on cast iron (ISO material group K). Suitable operations include turning, facing, boring, and back turning, making it a versatile choice for job shops and production cells running mixed steel and cast iron components. The neutral hand orientation fits standard right-hand and left-hand toolholders designed for DNMG-style inserts. The ISO designation for this insert is DNMG150404-FP5 WPP10G.

Key Features

• Multilayer CVD coating (TiCN, Al2O3, TiN) for extended wear life on steel and cast iron
• FP5 chip breaker geometry supports turning, facing, boring, and back turning
• 55-degree diamond insert shape with negative rake for rigid, stable cutting
• Chamfered and honed cutting edge reduces chipping on entry and exit
• Four cutting edges per insert for lower cost per edge
• Clamp and pin insert holding compatible - fits standard DNMG toolholders

Compatibility

Designed for use in DNMG-style toolholders that accept clamp and pin holding methods. ISO designation DNMG150404-FP5 WPP10G and ANSI designation DNMG431-FP5 WPP10G confirm fitment with holders built to ANSI and ISO DNMG standards. Primary workpiece material is steel (P10); secondary workpiece material is cast iron.

Installation Notes

Installation is performed by a licensed machinist or qualified CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Seat the insert fully against the toolholder pocket before tightening the clamp or pin to avoid micro-movement during cutting. Inspect the pocket and seating surface for chips or debris before installing a fresh edge.
