Iscar 5510185 DNMG432M3M IC6025 Turning Insert

Product Description

The ISCAR 5510185 is a DNMG432M3M-geometry turning insert in grade IC6025, designed for single-point turning operations on CNC and manual lathes. The insert is manufactured from solid carbide and finished with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN in that sequence, providing a combination of wear resistance and thermal protection suited to interrupted and continuous cuts. The 55-degree diamond shape (ISO code D) delivers a sharp, narrow cutting geometry. Key dimensional values include a 0.5-inch inscribed circle, a 0.625-inch insert length (15.5 mm), a 3/16-inch thickness (0.1875 inches), and a 1/32-inch corner radius (0.0313 inches). The M3M chip breaker geometry is optimized for positive-rake cutting action.

This insert is specified primarily for turning stainless steel workpieces, corresponding to ISO material group M. It is suited to general-purpose external turning, facing, and profiling passes where consistent chip control and edge integrity are required. Maximum depth of cut is 5.0 mm (0.197 inches). The insert is held by clamp or pin clamping methods, depending on the toolholder design. It belongs to ISCAR's Isoturn series and complies with ISO 13399 for tool data representation, making it compatible with CAM toolpath software that ingests ISO 13399 data. Machinists, CNC programmers, and toolroom technicians specify this insert for precision turning cells in job shop and production environments alike.

Key Features

• IC6025 solid carbide grade with CVD multilayer TiCN / Al2O3 / TiN coating for extended tool life on stainless steel
• 55-degree diamond insert shape (DNMG) with positive rake angle for reduced cutting forces
• M3M chip breaker geometry for reliable chip control across a range of feed and depth conditions
• 0 degrees relief angle (clearance code N) with tolerance code M for consistent dimensional accuracy
• Accepts clamp or pin holding methods, compatible with standard DNMG toolholders
• ISO 13399 compliant for direct import into CAM and tool management systems

Compatibility

Designed as an OEM-style replacement or direct-specification insert for toolholders accepting DNMG432 geometry inserts with clamp or pin holding, within the ISCAR Isoturn series.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or toolroom technician with the machine powered down and the spindle locked. Use the correct torque wrench and seating screw for the toolholder manufacturer's specified clamping torque — do not over-tighten, as this can fracture the carbide. Inspect the insert pocket and seating surfaces for chips or debris before seating the insert. Always verify tool offset data in the CNC controller after indexing or replacing an insert before returning the machine to cycle.
