Sumitomo 16CD487 Pcd Turning Insert DA2200 Diamond

Product Description

The SUMITOMO 16CD487 is a single-tipped Polycrystalline Diamond (PCD) turning insert designed for high-precision machining of non-ferrous metals. Built to ANSI code CNMX431 and ISO code CNMX120404, this insert features an 80-degree diamond shape with a positive rake angle of 10 degrees and a clearance code of N. The DA2200 grade PCD substrate with a coated finish delivers the cutting-edge hardness and wear resistance required for consistent performance in aluminum, copper, and other non-ferrous workpiece materials. It is installed by machinists and CNC lathe operators in both production and job-shop environments.

This insert is suited for turning operations on non-ferrous metals where surface finish and dimensional accuracy are critical. The CNMX insert style uses a clamp-and-pin holding method, making it compatible with standard CNMX-style tool holders. The X chip breaker geometry helps manage chip flow during continuous turning passes. Typical applications include finishing and semi-finishing passes on aluminum castings, copper alloys, and similar materials in aerospace, automotive, and general manufacturing settings.

Key Features

• Polycrystalline Diamond (PCD) insert material for superior hardness on non-ferrous workpieces
• DA2200 manufacturer grade with coated finish for extended tool life
• 80-degree diamond insert shape (ANSI CNMX431 / ISO CNMX120404) for versatile turning geometry
• Positive 10-degree rake angle reduces cutting forces on non-ferrous materials
• X chip breaker design promotes controlled chip evacuation
• Clamp and pin holding method for secure, repeatable insert positioning

Compatibility

Designed for use in CNMX-style tool holders that accept a 0.5 inch inscribed circle diamond-shaped insert with a clamp-and-pin holding method. Intended for turning non-ferrous metal workpieces per primary workpiece material code N.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and de-energize the machine tool completely before changing inserts. Use the appropriate torx or clamp screw driver as specified by the tool holder manufacturer to secure the clamp and pin without over-torquing. Confirm insert seating and alignment before resuming cutting operations.
