Sumitomo 16CDBAH Pcd Turning Insert 3/8 Inch Ic 55 Degree

Product Description

The SUMITOMO 16CDBAH is a Polycrystalline Diamond (PCD) turning insert designed for precision machining of non-ferrous metals. It features a diamond insert shape with a 55-degree included angle, a 3/8-inch inscribed circle, and a 0.0078-inch corner radius. The insert is 5/32 inches thick and uses a screw-holding method with positive rake geometry. Uncoated and manufactured to the DA2200 grade, this insert is suited for high-speed, fine-finish turning operations where tool life and edge consistency are critical. It conforms to ANSI and ISO 13399 standards and carries the ANSI code NFDCMX32.50.5 and ISO code NF-DCMT11T302.

This insert is intended for use on CNC lathes and turning centers in production and job-shop environments. Its PCD construction makes it well-suited for machining aluminum, copper, brass, and other non-ferrous workpiece materials where conventional carbide tooling experiences rapid wear. The positive rake and X-style chip breaker promote clean chip evacuation and reduced cutting forces, making this insert a practical choice for finishing passes on precision components.

Key Features

• Polycrystalline Diamond (PCD) insert material for extended tool life on non-ferrous metals
• 55-degree diamond insert shape with 3/8-inch inscribed circle and 7-degree relief angle
• 0.0078-inch corner radius for fine-finish turning applications
• Positive rake geometry with X-style chip breaker for efficient chip control
• Screw-holding method ensures secure seating in compatible toolholders
• Conforms to ANSI and ISO 13399 standards for broad toolholder compatibility

Compatibility

Designed for use in screw-lock turning toolholders accepting DCMX-style inserts with a C clearance code, M tolerance code, and 3/8-inch inscribed circle. Compatible with toolholders referencing ANSI code NFDCMX32.50.5 or ISO code NF-DCMT11T302.

Installation Notes

Installation is performed by a machinist or toolroom technician on a powered-down, fully stopped turning center or lathe. Use the appropriate torx or hex key to seat the screw-lock clamp to the toolholder manufacturer's specified torque. Inspect the insert pocket and clamp for chips or debris before seating to ensure proper contact and prevent premature edge failure. Never attempt to index or remove the insert while the spindle is in motion.
