Sumitomo 16CDWAW TPG431 Pcd Turning Insert 0.5in Triangle

Product Description

The SUMITOMO 16CDWAW is a Polycrystalline Diamond (PCD) turning insert designed for precision material removal on non-ferrous metals. Manufactured to the TPG431 insert standard, it features a triangular shape with a 60-degree included angle, a 0.5-inch inscribed circle, and a 3/16-inch insert thickness. The 1/64-inch (0.0156-inch) corner radius supports tight-tolerance finishing passes. Grade DA2200 PCD with a coated finish provides the hardness and wear resistance needed for high-speed turning of aluminum, copper, and other non-ferrous workpiece materials. Licensed machinists and CNC tooling technicians specify this insert for production turning operations where long tool life and consistent surface finish are critical.

This insert is suited for single-point turning operations on non-ferrous metals in both production and job-shop environments. The neutral rake geometry and 11-degree relief angle make it appropriate for external and facing cuts in conventional CNC lathe toolholders accepting TPG-style inserts. The clamp-holding method ensures positive seating in the toolholder pocket during continuous and interrupted cuts. Single-tipped construction means the cutting edge is a dedicated PCD tip, which is standard for non-ferrous finishing applications requiring edge consistency across a run.

Key Features

• Polycrystalline Diamond (PCD) insert material with coated DA2200 grade for non-ferrous cutting
• Triangular TPG431 insert style with 60-degree included angle and neutral rake angle (0 degrees)
• 0.5-inch inscribed circle (12.70 mm) with 3/16-inch insert thickness for rigid toolholder seating
• 1/64-inch (0.0156-inch) corner radius for fine finishing on tight-tolerance workpieces
• Clamp-style insert holding method with clearance code P and tolerance code G
• Conforms to ANSI and ISO 13399 standards; ISO code TPGN220404

Compatibility

Designed as an OEM-style replacement for TPG-style PCD turning insert applications in CNC lathe toolholders accepting a 0.5-inch inscribed circle triangular insert with clamp-style retention.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machining professionals. Before changing inserts, ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamp for chips or wear before seating the new insert to ensure proper contact and prevent premature edge failure.
