Seco 02615968 Turning Insert Rnmg 64-MR4 TS2500 Carbide

Product Description

The SECO 02615968 is a solid carbide turning insert in the RNMG 64-MR4 series, designed for high-performance material removal in demanding machining environments. It carries a multilayer TiAlN and TiN coating applied via PVD process, which promotes heat resistance and edge durability during interrupted and continuous cuts. The insert features a round shape with a 0.75-inch inscribed circle, a 0.375-inch corner radius, and a 0.25-inch thickness. With eight available cutting edges and a neutral hand orientation, it delivers consistent performance across facing, profiling, and turning operations. This insert is suited for machinists and tooling technicians running modern CNC turning centers.

The 02615968 is optimized for primary use on superalloys and titanium, carrying an ISO material code of S, with secondary suitability for steel, stainless steel, and cast iron. The MR4 chip breaker geometry and T-Land cutting edge style are engineered to manage chip flow and reduce cutting forces in tough materials. The TS2500 manufacturer grade is assigned to SECO material grades S10 and S20, making this insert a practical choice for high-temperature alloy turning where edge wear and thermal fatigue are the primary concerns. Multi-use applications include facing, profiling, and general turning.

Key Features

• Round insert shape with 0.75-inch inscribed circle and 0.375-inch corner radius for full-radius cuts
• Multilayer TiAlN and TiN PVD coating for heat resistance and extended tool life in difficult alloys
• Eight cutting edges per insert with neutral hand orientation for maximum value per unit
• MR4 chip breaker with T-Land cutting edge style designed for chip control on superalloys and titanium
• Compatible with clamp, pin, and lever lock insert holding methods
• Meets ANSI and ISO standards; ISO code RNMG190600-MR4

Compatibility

Designed for use in standard RNMG-style toolholders that accept clamp, pin, or lever lock retention. Compatible with turning operations on superalloys and titanium as the primary workpiece material, with secondary suitability for steel, stainless steel, and cast iron applications.

Installation Notes

Installation is performed by a qualified machinist or tooling technician on a CNC or manual turning center. Always power down and lock out the machine before seating or replacing inserts. Verify the toolholder is clean and free of debris before installing; foreign material under the insert seat can cause premature edge failure or insert breakage. Follow the toolholder manufacturer torque specifications for the clamping screw or lever lock mechanism.
