Seco 02615956 Cnmg 432-MR4 TS2500 Turning Insert Carbide

Product Description

The SECO 02615956 is a CNMG 432-MR4 indexable turning insert manufactured from solid carbide and finished with a multilayer PVD TiAlN and TiN coating. Carrying the TS2500 manufacturer grade, this insert is engineered primarily for machining superalloys and titanium, with secondary suitability for steel, stainless steel, and cast iron. It features an 80-degree diamond insert shape, a negative rake geometry, and a T-Land cutting edge style paired with the MR4 chip breaker. With four usable cutting edges and a 0.5-inch inscribed circle, this insert is suited for high-productivity turning, facing, and boring operations on CNC lathes and turning centers. Licensed machinists and toolroom professionals select this grade for demanding aerospace and energy-sector workpieces.

The 02615956 fits standard CNMG-style toolholders and is applicable across a range of turning center setups in both job shop and production environments. Compatible holding methods include clamp, pin, and lever lock styles. The MR4 chip breaker geometry is optimized for moderate to heavy material removal on difficult-to-machine superalloys and titanium alloys. It also performs reliably in steel and stainless steel finishing and semi-finishing passes. This insert follows both ANSI and ISO standards, with an ISO designation of CNMG120408-MR4 and an industry standard number of CNMG432-MR4, making cross-referencing to toolholder catalogs straightforward.

Key Features

• Negative rake, neutral hand geometry compatible with clamp, pin, and lever lock toolholders
• Multi-use application: boring, facing, and turning from a single insert style
• Conforms to ANSI and ISO standards; ISO code CNMG120408-MR4

Compatibility

Designed for use in CNMG-style toolholders accepting a 432 insert size with clamp, pin, or lever lock holding methods. Meets ANSI and ISO standards; ISO designation CNMG120408-MR4, industry standard number CNMG432-MR4. Suitable for CNC turning, facing, and boring applications on superalloys, titanium, steel, stainless steel, and cast iron workpieces.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully against the toolholder pocket and tighten the clamping screw or lever to the toolholder manufacturer specifications. Inspect the insert pocket for chips or debris before seating a new cutting edge to ensure proper support and prevent premature edge failure.
