Sumitomo 16CDBDX Pcd Turning Insert 3/8 Inch Ic

Product Description

The SUMITOMO 16CDBDX is a Polycrystalline Diamond (PCD) turning insert designed for high-precision machining of non-ferrous metals. Manufactured to the DA2200 grade, this uncoated insert features a 35-degree diamond shape (Insert Shape Code V) with a positive rake geometry and a clearance code of C. The 3/8-inch inscribed circle and 1/64-inch corner radius (0.0156 inches) make it well suited for finish and semi-finish turning operations where tight tolerances and sharp cutting edges are critical. The screw-holding method provides secure seating in compatible toolholders. Machining professionals working with aluminum, copper, brass, and other non-ferrous workpiece materials rely on PCD inserts like this one for extended tool life and consistent surface finish.

This insert is intended for turning applications on non-ferrous metals in both production and job-shop environments. The NF-VCMX insert style and positive rake geometry reduce cutting forces, making it appropriate for light to medium material removal on materials prone to built-up edge with conventional carbide. The insert conforms to ANSI code NFVCMX331 and ISO code NF-VCMT160404, meeting ANSI and ISO 13399 standards, which simplifies tooling documentation and integration into CAM systems. It is typically installed and managed by CNC machinists, tool-and-die professionals, and precision turning specialists.

Key Features

• Polycrystalline Diamond (PCD) insert material for superior wear resistance on non-ferrous workpieces
• DA2200 manufacturer grade with uncoated finish optimized for non-ferrous metal cutting
• 35-degree diamond insert shape with positive rake for reduced cutting forces
• 1/64-inch corner radius (0.0156 inches) for precise edge geometry and finish quality
• Screw-holding method ensures rigid, repeatable insert positioning
• Compliant with ANSI and ISO 13399 standards for cross-system tooling compatibility

Compatibility

Designed as an OEM-style replacement and standard fit for toolholders accepting NF-VCMX style inserts with a 3/8-inch inscribed circle and screw-clamp holding method. Verify toolholder seat geometry and insert pocket dimensions before installation. Primary workpiece material compatibility is non-ferrous metals per material grade C2 designation.

Installation Notes

PCD turning inserts are installed by qualified CNC machinists or tooling technicians. Always power down and lock out the machine spindle before changing inserts. Use the correct torque driver for the clamping screw to avoid cracking the PCD substrate — consult the toolholder manufacturer's seating specifications. PCD inserts are not suitable for ferrous materials or interrupted cuts; verify workpiece material before use to prevent premature insert failure.
