Sumitomo 16HQWHQ Pcd Turning Insert Vnmx 3/8 in Ic

Product Description

The SUMITOMO 16HQWHQ is a Polycrystalline Diamond (PCD) turning insert designed for high-performance machining of non-ferrous metals. Manufactured to the VNMX insert style with a 35-degree diamond shape, this insert features a 3/8-inch inscribed circle, a 1/64-inch corner radius, and an uncoated PCD cutting edge. The DA1000 material grade delivers exceptional wear resistance and edge retention on aluminum, copper, and other non-ferrous workpiece materials. Rated for neutral cutting direction with a negative rake angle and zero relief angle, it is suited for stable, repeatable turning operations. CNC machinists and toolroom technicians install this insert into compatible VNMX-style toolholders for production and precision turning applications.

This insert is intended for turning operations on non-ferrous metal workpieces, including aluminum alloys and copper-based materials where PCD tooling is the standard choice for extended tool life and superior surface finish. The VNMX331GD geometry with the X chip breaker designation accommodates a range of depth-of-cut and feed conditions typical in high-volume CNC turning. It is equally applicable in job-shop and production environments where consistent edge performance is required.

Installation Notes

This insert is installed and replaced by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat the insert securely via the pin and screw holding method, and verify proper seating in the toolholder pocket before resuming cuts. Do not use PCD inserts on ferrous or hardened steel workpieces.
