Seco 02578578 Indexable Cutoff Blade Series 150.10

Product Description

The SECO 02578578 is a single-end neutral indexable cutoff blade designed for parting operations on CNC and manual lathes. The blade measures 0.61 inches high, 0.094 inches wide, and 1.303 inches in overall length, with a minimum insert width of 0.122 inches and an insert corner radius of 0.008 inches. It uses a self-grip insert holding method, which secures the insert without additional fasteners, reducing changeover time at the machine. Built to ISO standards, this blade fits the Series 150.10 system and is compatible with both left-hand and right-hand cutting directions. Machinists and toolroom technicians handling production parting and grooving work are the primary users.

This cutoff blade is suited for parting applications on workpieces up to 1.5 inches in diameter. It belongs to the Series 150.10 system and is designed for use with the 150.10-15 tool block style. The neutral cutting geometry makes it adaptable for both left-hand and right-hand setups without requiring a dedicated blade for each orientation. Typical environments include production turning cells, job shops, and maintenance toolrooms where consistent parting depth and insert repeatability are priorities.
