Seco 02578581 Indexable Cutoff Blade Series 150.10

Product Description

The SECO 02578581 is a double-end neutral indexable cutoff blade engineered for parting and grooving operations on CNC lathes and turning centers. The blade measures 0.843 inches high, 0.079 inches wide, and 4.72 inches overall length, making it suited for close-clearance parting work where rigidity and dimensional accuracy matter. It uses a self-grip insert holding method, which secures inserts without screws for fast indexing under production conditions. The blade accepts inserts with a 0.098-inch minimum insert width and a 0.007-inch corner radius. Both ends are usable, extending service life between blade replacements. This part is installed by machinists and CNC tooling technicians working in metal-cutting environments.

The 02578581 is designed for parting and cutoff applications where the maximum workpiece diameter does not exceed 1.4 inches. It mounts in a 150.10-20 series tool block or toolholder. The neutral cutting direction and left-hand and right-hand compatibility make it adaptable to a range of turret configurations. Typical use is in production turning of bar stock in steel, stainless, aluminum, and similar materials where consistent cutoff width and insert repeatability are required. The blade conforms to ISO standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and all motion is locked out before mounting or indexing the blade. Seat the blade fully in the tool block and verify insert engagement before resuming cuts. Do not exceed the stated maximum workpiece diameter to avoid overloading the blade or insert seat.
