Sumitomo 16HQBZS Turning Insert Pcd Nf-tpg 3/8 Ic

Product Description

The SUMITOMO 16HQBZS is a polycrystalline diamond (PCD) turning insert designed for precision machining of non-ferrous metals. Configured in the NF-TPG style with a 60-degree triangular insert shape, it features a 3/8-inch inscribed circle, a 1/64-inch corner radius, and a 0.1142-inch insert length. The positive rake geometry and 11-degree relief angle reduce cutting forces and promote clean chip formation. This insert is intended for use by machinists and toolroom professionals running CNC or manual turning centers where surface finish and dimensional accuracy on non-ferrous workpieces are critical.

The 16HQBZS is applied in turning operations on non-ferrous materials such as aluminum alloys, copper, brass, and similar soft metals where PCD tooling delivers superior tool life and finish quality. It fits Series T toolholders using a clamp-style insert holding method. With a 1/8-inch insert thickness and clearance code P with tolerance code G, it suits production environments requiring consistent, repeatable results on high-volume non-ferrous turning work.

Key Features

• Polycrystalline diamond (PCD) insert material for extended tool life on non-ferrous metals
• 60-degree triangular insert shape (NF-TPG style) with positive rake geometry
• 3/8-inch inscribed circle and 1/64-inch corner radius for precise cutting edge geometry
• 11-degree relief angle and positive rake angle reduce cutting forces
• Clamp-style insert holding method for secure seating in Series T toolholders
• Conforms to ANSI and ISO 13399 standards; ISO code NF-TPGN160304

Compatibility

Designed for use with Series T clamp-style toolholders configured for NF-TPG triangular turning inserts with a 3/8-inch inscribed circle. Intended for primary use on non-ferrous metal workpieces per ISO material code N.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the turning center is powered down and the spindle is fully stopped before indexing or replacing inserts. Use the correct torque driver or clamp screw specified by the toolholder manufacturer to seat the insert securely without over-tightening. Verify insert orientation and seating before resuming cutting operations.
