Sumitomo 16CDBCH Pcd Turning Insert 3/8 in Ic Triangle

Product Description

The SUMITOMO 16CDBCH is a Polycrystalline Diamond (PCD) turning insert designed for precision machining of non-ferrous metals. Built to ANSI and ISO 13399 standards, this uncoated triangular insert features a 60-degree included angle, a 3/8-inch inscribed circle, and a 1/32-inch corner radius. The DA2200 grade PCD material provides exceptional hardness and wear resistance suited for high-speed finishing and semi-finishing passes on aluminum, copper, and other non-ferrous workpiece materials. It is held in place using a clamp and pin system and is compatible with positive-rake toolholders. Machinists and tooling specialists in production and job-shop environments will find this insert well-suited for tight-tolerance turning applications.

This insert is intended for use on CNC lathes and turning centers handling non-ferrous metal components. The positive rake geometry reduces cutting forces, making it appropriate for thin-wall or chatter-sensitive workpieces. The X chip breaker designation supports controlled chip evacuation during continuous turning operations. The NF-TNMX insert style and ANSI code NFTNMX332 align with standard toolholder systems, simplifying integration into existing setups. This is a single-piece packaged item with a minimum order quantity of one.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the turret is locked before seating or indexing inserts. Verify that the toolholder pocket and clamping surfaces are clean and free of chips before installing the insert. Follow the toolholder manufacturer's clamping torque specifications and consult applicable shop safety procedures when working near cutting edges.
