Sumitomo 16DTASY Pcbn Turning Insert 80 Degree 1/4 in Ic

Product Description

The SUMITOMO 16DTASY is a Polycrystalline Cubic Boron Nitride (PCBN) turning insert designed for precision single-point turning operations on hardened ferrous workpieces, including hardened steel and similar difficult-to-machine materials. Built to ANSI and ISO 13399 standards, this insert carries the BNC200 manufacturer grade and features a Physical Vapor Deposition (PVD) Titanium Nitride (TiN) coating for improved surface finish and edge wear resistance. The 2NC-CCGA insert style provides a positive rake geometry with a 7-degree relief angle. It is installed and serviced by CNC machinists and toolroom technicians working with indexable toolholders.

This insert is suited for hard turning applications in production machining environments where consistent surface finish and tight tolerances are required. The 80-degree diamond insert shape with a 0.0078 inch corner radius supports profiling and finish turning passes. The secondary workpiece material designation is steel (ISO code H), making this insert applicable to hardened steel turning as a primary use case. A maximum depth of cut of 0.0150 inches reflects its role in light, precision finishing cuts rather than heavy roughing operations.

Key Features

• PCBN insert material for hard turning of ferrous and steel workpieces
• BNC200 grade with PVD Titanium Nitride (TiN) coating for edge integrity and surface finish
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• 0.0078 inch corner radius suited to finish turning and light profiling
• Screw-held mounting in compatible 2NC-CCGA style indexable toolholders
• Meets ANSI and ISO 13399 standards; ISO code 2NC-CCGW060202

Compatibility

Designed for use in indexable toolholders accepting the 2NC-CCGA insert style with a screw-clamp holding method. ISO insert code 2NC-CCGW060202. Compatible toolholders must accommodate a 0.1100 inch hole diameter and the C-series insert geometry. Verify toolholder specifications before installation.

Installation Notes

This insert is installed by qualified CNC machinists or toolroom technicians using the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specification. Always power down and lock out the machine spindle before indexing or replacing inserts. Do not exceed the maximum depth of cut listed for this insert grade, as PCBN inserts are brittle and susceptible to edge chipping under interrupted cuts or excessive radial engagement. Confirm workpiece hardness and material compatibility with the BNC200 grade prior to use.
