TDXU: Specifies the proprietary product family name for double-ended, pressed-type multi-functional inserts. This design supports a wide variety of operations, allowing the same tool to transition between plunge grooving and side turning.
5 (Seat Size / Width): Indicates a Cutting Width (\(CW\)) of 5.0 mm (\(0.197\text{ inches}\)). It also mandates the matching Size 5 tool holder seat pocket configuration (\(SSC\text{ 5}\)).
E (Geometry/Application): Represents a neutral, flat-top, pressed utility classification optimized for general purpose external, internal, and face groove-turn machining.
-0.8 (Corner Radius): Defines a precise corner nose radius (\(RE\)) of 0.8 mm (\(0.031\text{ inches}\)). This wide profile radius provides a smooth, polished final surface finish while reinforcing the cutting edge corners against heavy radial chipping.
2. Carbide Substrate & Coating Specifications
TT9030 Grade: This denotes a specialized TaeguTec PVD (Physical Vapor Deposition) coated carbide grade. It features a sub-micron substrate layered with a sub-micron TiAlN + TiN structural matrix.
Material Specialisation: The combination yields exceptional thermal stability and edge toughness. It is primarily engineered for the reliable medium-to-low speed machining of:
