Seco 02578582 Double End Neutral Indexable Cutoff Blade

Product Description

The SECO 02578582 is a double-end neutral indexable cutoff blade engineered for parting and grooving operations on CNC lathes and turning centers. It measures 0.843 inches high, 0.094 inches wide, and 4.72 inches overall length, with a minimum insert width of 0.122 inches. The blade uses a self-grip insert holding method, which eliminates the need for additional clamping hardware and provides repeatable insert positioning. Designed to the ISO standard, this blade is compatible with the 150.10 series tool block system and accepts inserts from the 150.10-3 family. It handles both left-hand and right-hand cutting directions, making it adaptable to a range of turning setups. Machinists and CNC operators in production and job-shop environments install this blade as part of a modular parting system.

This blade is suited for parting and cutoff applications on workpieces up to 3.4 inches in diameter. It fits into 150.10-...-20 series tool blocks and is used in both high-volume production turning and general-purpose machining environments. The 150.10A blade style is a recognized modular system component, allowing quick insert changes without removing the blade from the holder. Typical applications include bar stock cutoff, groove turning, and face grooving on steel, stainless, aluminum, and similar materials processed on manual or CNC lathes.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before changing inserts or mounting the blade, ensure the machine is powered down and the spindle is fully stopped. Seat the blade securely in the tool block and confirm the self-grip insert is fully engaged before resuming cuts. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when setting tool height and offset values.
