Sumitomo 16HQEGJ Pcd Turning Insert 3/8 Inch Ic

Product Description

The SUMITOMO 16HQEGJ is a Polycrystalline Diamond (PCD) turning insert designed for precision machining of non-ferrous metals. This DCMT-style insert features a 55-degree diamond shape with a 3/8-inch inscribed circle and a 1/64-inch corner radius. It is uncoated and carries manufacturer grade DA1000, which is suited for high-speed, high-precision turning applications where surface finish and tool life are critical. The neutral hand orientation and positive rake angle make it compatible with standard DCMT toolholders. Licensed machinists and CNC operators install this insert in turning centers and lathes for finishing and semi-finishing passes on aluminum, copper, and other non-ferrous workpiece materials.

This insert is intended for use in turning applications involving non-ferrous metals such as aluminum alloys, copper, brass, and similar materials. Its PCD construction delivers exceptional wear resistance and edge retention in high-speed cutting conditions. The chip breaker designation T supports controlled chip formation during continuous turning operations. The insert fits toolholders using pin and screw holding methods and is appropriate for both production-run and job-shop turning environments where consistent dimensional accuracy is required.

Key Features

• Polycrystalline Diamond (PCD) insert material for high wear resistance in non-ferrous applications
• DCMT insert style with 55-degree diamond shape and neutral hand orientation
• 3/8-inch inscribed circle with 1/64-inch corner radius for precision contouring
• Positive rake angle reduces cutting forces and heat generation
• Compatible with pin and screw insert holding methods
• Meets ANSI and ISO 13399 standards; ISO code NF-DCMT11T304N-GD

Compatibility

Designed as an OEM-style replacement or direct-fit insert for DCMT-style toolholders that accept a 3/8-inch inscribed circle, pin and screw holding, with clearance code C and tolerance code M, for non-ferrous turning operations.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torx or hex key to secure the clamping screw to the toolholder manufacturer specification. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper seating and prevent premature edge failure.
