See Downloads section below item photos for detailed product information, technical information and compatible boring bars. Key benefits High wear resistance and longer edge life: TiAlN coated DURA‑MAX 3000 carbide provides strong heat and oxidation resistance for extended tool life in demanding materials. Precise finishing and repeatability: .002" radius and a ground chipbreaker deliver consistent surface finish and predictable chip control on internal bores. Cost‑effective indexing: Triangle insert with 3 cutting edges allows quick indexing to a fresh edge, reducing downtime. Broad material capability: Engineered for steel, titanium, nickel alloys, and stainless steel so one insert works across multiple jobs. What this insert is and how it solves problems Function: Indexable turning/boring insert designed for internal boring operations where tight radii and good surface finish are required. Problem solved: Reduces frequency of insert changes and rework caused by wear or poor chip control when machining hard-to-cut alloys. Standout features: TiAlN coating for higher temperature stability, left‑hand ground chipbreaker for improved chip evacuation, and compact .160" I.C. for access in smaller bores. Key specifications (exact) Grade/Coating: TiAlN Coated DURA‑MAX 3000 carbide Insert shape/size: Triangle insert, .160" I.C. (inscribed circle) Cutting edges: 3 usable cutting edges per insert Corner radius: .002" Chipbreaker: Left Hand ground chipbreaker Compatible toolholder styles: Use MBB Series or ANSI TD style boring bars Performance and usage notes Best for finishing and light to medium depth profiling where surface finish and dimensional accuracy matter. Left hand chipbreaker indicates the chip control geometry and recommended cutting direction; ensure matching left‑hand toolholder or insert orientation during setup. Compact .160" I.C. makes the insert suitable for tighter internal bores where larger inserts will not fit. Practical application examples Aerospace titanium components: Finishing internal bores on Ti‑6Al‑4V landing gear or actuator housings where heat resistance and edge life are critical. Stainless steel valve bodies and hydraulic fittings: Produces consistent surface finish and accurate diameters in small‑bore operations. Nickel‑based superalloy workpieces: Boarding and finishing internal features on gas turbine components where improved coating durability reduces tool changes. Compatibility and purchasing tips Use only with MBB Series or ANSI TD style boring bars to ensure correct mechanical support and insert seating. Refer to the Downloads section below the item photos for full technical data, insert geometry drawings, and a list of compatible boring bars and holder part numbers before ordering. Handling and setup reminders Verify toolholder orientation matches left‑hand chipbreaker geometry. Maintain recommended cutting parameters for each material (see Downloads) to maximize coating and insert life. Inspect insert seating and clamp torque at each index to ensure repeatable accuracy. This insert is intended for precision internal turning where a small‑I.C., TiAlN coated triangle insert with a .002" radius and left‑hand ground chipbreaker offers durability, chip control, and three usable edges per insert.
