Precise internal grooving with a compact, indexable carbide insert that creates true full-radius (R1) grooves. Designed for machinists who need consistent, efficient internal machining on challenging materials.

• Full-radius internal grooving: Produces round-bottom grooves for smooth transitions and reliable seal seating inside bores.
• Internal bore compatibility: Internal minimum bore diameter of 14.0 mm (0.55 in) supports standard internal feature work.
• Dimensions and geometry: 14 mm min bore, 2 mm width, R1 full-radius edge, T10 form for precise seating in the toolholder.
• Carbide grade and coating: BLU PVD triple-layer coated sub-micron carbide for enhanced wear resistance and durability.
• Material compatibility: Suitable for stainless steels, cast iron, titanium, non-ferrous metals, and many high-temperature alloys (M10–M20, K05–K20, N10–N20, S10–S20).
• Indexable design: Quick, repeatable insert indexing to minimize downtime and maintain consistent groove depth.

This insert delivers dependable performance in internal grooving tasks, helping you achieve clean finishes and stable groove dimensions across production runs. The BLU PVD coating reduces wear in tough materials, while the full-radius profile minimizes sharp corners and stress concentrations for longer tool life and better part integrity.
