Seco 00041713 Turning Insert CNMG431-MR4 883 Carbide

Product Description

The SECO 00041713 is an uncoated solid carbide turning insert in the CNMG431-MR4 series, designed for demanding metal-cutting operations in superalloys and titanium. Conforming to ANSI insert code CNMG431 and ISO code CNMG120404-MR4, this insert features an 80-degree diamond (rhombic) shape with a negative rake and negative side clearance. The MR4 chip breaker geometry is engineered for roughing and medium machining passes, delivering a balance of high wear resistance and toughness across material grades S10, S20, and S30. With four usable cutting edges per insert, it delivers solid value in high-volume turning environments. Licensed machinists and CNC operators working in aerospace, energy, and advanced manufacturing applications install and index this insert.

This insert is suited for external and internal turning operations including boring, facing, and general turning on superalloys, titanium, and secondary workpiece materials classified under ISO codes M, K, N, and H. The CNMG431-MR4 geometry accommodates a maximum depth of cut of 0.4921 inches and is compatible with toolholders that accept clamp, pin, or lever-lock holding methods. It is appropriate for both production and job-shop environments where difficult-to-machine materials require consistent edge performance across multiple passes.

Key Features

• 80-degree diamond (rhombic) insert shape with T-Land cutting edge style for edge strength in interrupted and continuous cuts
• MR4 chip breaker geometry rated for roughing and medium machining of superalloys and titanium
• Uncoated (bright) solid carbide substrate — material grades S10, S20, S30 for high wear resistance to high toughness range
• Four cutting edges per insert — neutral hand orientation for flexible toolholder use
• Maximum depth of cut: 0.4921 inches; inscribed circle: 0.5000 inches (12.70 mm)
• Compatible with clamp, pin, and lever-lock holding methods
• Meets ANSI and ISO standards; multi-use for boring, facing, and turning

Compatibility

Designed for use in CNMG-style toolholders accepting clamp, pin, or lever-lock holding methods. Compatible with toolholders sized for a 0.5000-inch inscribed circle and 0.1874-inch insert thickness. Primary workpiece material is superalloys and titanium (ISO code S); secondary materials include ISO codes M, K, N, and H.

Installation Notes

Indexing and replacement of carbide turning inserts is performed by qualified machinists or CNC technicians following machine lockout and spindle-stop procedures before any toolholder access. Ensure the toolholder seat and clamping surfaces are clean and free of chips before seating the insert. Follow the toolholder manufacturer's clamping torque guidelines for the specific clamp, pin, or lever-lock system in use. Inspect the cutting edge for chipping or wear before each use and do not continue cutting with a damaged edge.
