Widia 2828398 Boring Insert TDAT130805 CG5 Carbide Tin

Product Description

The WIDIA 2828398 is a triangular carbide boring insert designed for precision material removal in boring operations across a range of workpiece materials. Manufactured to ANSI and ISO standards, this insert carries the ANSI code TDHH130805 and ISO code TDHH07S102. The carbide substrate uses a micrograin grade designated CG5 and is PVD-coated with titanium nitride (TiN) for improved wear resistance and surface hardness. With a 60-degree included angle, a 0.007 inch corner radius, and a 15-degree relief angle with a positive rake, this insert is built for consistent, repeatable cuts in tight-tolerance boring applications. Licensed machinists and tooling technicians working on CNC or manual boring setups will find this insert suited for medium to fine finishing passes.

This insert is intended for use in boring operations on a broad range of materials, including steel, stainless steel, non-ferrous alloys, high-temperature alloys, and cast iron. The universal primary workpiece material classification (M, N, P, S codes) alongside a secondary cast iron rating (K code) reflects its versatility across production environments. It fits tool holders designed for the TDAT insert style within the TDHH series, making it applicable in both light industrial and high-production machining contexts. The screw-in holding method provides secure clamping and repeatable indexing, which matters when maintaining consistent bore geometry across multiple parts.

Key Features

• Micrograin carbide substrate with CG5 grade for edge stability and wear resistance
• PVD titanium nitride (TiN) coating for extended tool life on a wide range of materials
• 60-degree triangular shape with 3 cutting edges for maximum index value per insert
• Positive rake and 15-degree relief angle for reduced cutting forces during boring passes
• Chipbreaker geometry supports chip control in continuous and interrupted cuts
• Screw-in holding method ensures rigid seating and accurate repositioning on index

Compatibility

Designed for use with TDHH-series boring tool holders that accept TDAT-style inserts. ANSI code TDHH130805 and ISO code TDHH07S102 can be used to confirm holder compatibility. Verify tool holder specifications before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with indexable insert systems. Power down and de-energize the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the tool holder manufacturer's specified procedure. Inspect the insert pocket and screw threads for wear or debris before seating a new insert to ensure proper clamping force and alignment.
