Seco 00098983 Turning Insert SNMG644-MR3 CP500 Carbide

Product Description

The SECO 00098983 is a solid carbide turning insert in the SNMG-MR3 series, designed for high-performance material removal in CNC turning operations. It carries the SNMG644-MR3 industry standard designation and the ISO code SNMG190616-MR3. The insert features a multilayer PVD coating combining TiAlN and TiN for enhanced wear resistance and thermal stability. With a 3/4-inch inscribed circle, 1/4-inch thickness, and a 1/16-inch corner radius, this is a full-size SNMG insert suited for medium to heavy cutting passes. The CP500 grade is engineered to balance toughness with wear resistance across demanding workpiece materials. The MR3 chip breaker geometry targets roughing and medium machining applications.

This insert is intended for use on CNC lathes and turning centers in metalworking environments. Its neutral hand orientation makes it compatible with standard right-hand toolholders using clamp, pin, or lever lock holding methods. Multi-use application includes turning, facing, and boring operations. Primary workpiece materials include stainless steel, steel, and cast iron, with rated capability on superalloys and titanium as secondary materials. The insert is suited for production machining shops, job shops, and maintenance machining environments where consistent chip control across roughing and medium passes is required. It ships individually but carries a minimum order quantity of 10 units.

Key Features

• CP500 grade with multilayer PVD TiAlN and TiN coating for wear resistance and toughness on steel, cast iron, and superalloys
• MR3 chip breaker geometry optimized for roughing and medium machining operations
• 8 usable cutting edges per insert for extended tool life and cost efficiency
• Neutral hand orientation compatible with clamp, pin, and lever lock toolholders
• Chamfered and honed cutting edge style for edge stability under interrupted and continuous cuts
• Rated for turning, facing, and boring multi-use applications on a single insert geometry

Compatibility

Designed for use in SNMG-style toolholders that accept a 3/4-inch inscribed circle square insert with negative rake and negative side clearance. Compatible holding methods include clamp, pin, and lever lock systems conforming to ANSI and ISO SNMG190616 standards.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and the spindle locked before changing inserts. Use the appropriate torque wrench per the toolholder manufacturer specifications when tightening the clamp or lever lock screw. Inspect the toolholder pocket and seating surface for chips or wear before seating a new insert. Do not exceed the maximum depth of cut of 0.687 inches as specified for this insert size.
