Mitsubishi 10587218 DNMG433 Carbide Turning Insert

Product Description

The MITSUBISHI 10587218 is a DNMG-style indexable turning insert designed for metal cutting operations on CNC lathes and turning centers. Built from carbide with a PVD coating and MITSUBISHI manufacturer grade MP9015, this insert is engineered for high wear resistance with moderate toughness, making it well suited for machining special and super alloys in the S material category. The insert features a 55-degree diamond (rhombic) shape, a neutral hand orientation, and a corner radius of 1.20 mm (3/64 inch), delivering precise, repeatable cutting geometry across four usable cutting edges.

This insert is intended for medium machining chip breaker operation using the MA chip breaker configuration. It is used in production turning environments where super alloys such as titanium, Inconel, and similar high-temperature alloys are common workpiece materials. Licensed machinists and CNC operators working in aerospace, energy, and precision manufacturing are the primary installers and users. The negative side clearance and DNMG form factor make it compatible with standard DNMG insert pockets on qualified toolholders.

Key Features

• Carbide substrate with PVD coating for extended tool life in super alloy applications
• MP9015 grade optimized for high wear resistance to moderate wear resistance and toughness
• 55-degree diamond insert shape with four cutting edges for cost-efficient indexing
• 1.20 mm corner radius suitable for medium finishing and semi-roughing passes
• MA chip breaker geometry tuned for medium machining operations
• Neutral hand orientation fits standard DNMG right-hand and left-hand toolholders

Compatibility

Designed as a direct-fit replacement for DNMG433 (ISO: DNMG150412) insert pockets on standard DNMG-compatible turning toolholders. Verify toolholder pocket tolerance and clamping system before indexing.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before handling inserts, as cutting edges are sharp and can cause serious injury. Use proper insert handling tools and torque the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket seat for debris or damage before seating a new insert.
