Iscar 2550056 Indexable Grooving Blade Left Hand

Product Description

The ISCAR 2550056 is a left-hand indexable grooving blade from the Heliface series, designed for grooving, parting, and turning operations on CNC lathes and turning centers. The blade stands 1.26 inches high with a blade width of 0.204 inches and an overall length of 2.874 inches. It accepts a wide range of indexable insert styles, making it a versatile toolholder for production and job-shop turning applications. Maximum depth of cut reaches 1.2598 inches (32 mm). This blade is installed by machinists and CNC tooling technicians working on precision turning equipment.

The 2550056 is suited for external grooving, parting, and profiling on workpieces ranging from 7.087 inches (180 mm) minimum to 15.748 inches (400 mm) maximum diameter. Its left-hand cutting direction and Heliface blade style make it appropriate for specific toolholder orientations on gang-tool and turret-style turning centers. Compatible insert styles include DGN/DGNC/DGNM-C, DGN/DGNM-J/JS/JT, DGN-UT/UA, DGN-W, GRIP, HFPR/L, and HGPL, giving tooling engineers broad insert selection flexibility within a single blade body.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machinists. Before mounting or changing inserts, ensure the machine is in an E-stop or powered-down state and that the spindle is fully stopped. Use the appropriate torque wrench and ISCAR-specified clamping hardware when seating the blade in the toolholder block. Verify cutting direction and blade orientation against the machine turret setup before resuming operation.
