Sumitomo 16CDBCL Pcd Turning Insert 3/8 in Ic 35 Deg

Product Description

The SUMITOMO 16CDBCL is a Polycrystalline Diamond (PCD) turning insert designed for precision machining of non-ferrous metals. Built to ANSI code NFVNMX331 and ISO 13399 standard NF-VNMX160404, this uncoated insert features a 35-degree diamond shape with a positive rake geometry. The 3/8-inch inscribed circle and 1/64-inch corner radius make it well-suited for finish and semi-finish turning operations where tight tolerances and sharp edge retention are critical. It is installed and changed by CNC machinists and toolroom technicians working with non-ferrous workpiece materials such as aluminum, copper, and brass alloys.

This insert is used in turning centers and CNC lathes performing light to medium material removal on non-ferrous metals. The NF-VNMX insert style and positive rake angle reduce cutting forces and heat generation, which is especially important when machining gummy or thermally sensitive materials. The clamp and pin holding method provides rigid seating in compatible toolholders. Its compact 3/16-inch thickness and 0.252-inch insert length suit smaller-profile toolholder pockets commonly found in precision turning applications.

Key Features

• Polycrystalline Diamond (PCD) insert material for extended tool life on non-ferrous workpieces
• Uncoated DA2200 grade with positive rake geometry reduces cutting forces
• 35-degree diamond insert shape (ANSI NFVNMX331) for access in tight-clearance cuts
• 1/64-inch (0.0156-inch) corner radius supports fine surface finish requirements
• Clamp and pin holding method ensures secure, repeatable seating in toolholder
• Compliant with ANSI and ISO 13399 standards for insert identification and interchangeability

Compatibility

Designed for use in NF-VNMX style toolholders that accept a 3/8-inch inscribed circle, VNMX-series turning insert with a 0.150-inch hole diameter and clamp-and-pin holding method. Consult toolholder documentation to confirm pocket geometry and clamping system compatibility before installation.

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 for the clamping screw and follow the toolholder manufacturer's specified seating procedure. Inspect the insert pocket and locating pin for wear or debris before seating the new insert.
