Product Description

The ISCAR 2550139 is an indexable grooving blade designed for grooving, parting, and turning operations on CNC lathes and turning centers. Part of the Modular Grip series, this left-hand blade measures 1.2598 inches in height and 0.2480 inches in width, with an overall length of 1.5945 inches. It accepts HFPR/L style inserts and delivers a maximum depth of cut of 0.5512 inches. Machinists and tooling specialists working with small-diameter workpieces will find this blade well-suited to precision grooving applications where tight dimensional control is required. The blade conforms to ISO 13399 tooling data standards.

This blade is intended for use in applications involving workpieces with a minimum diameter of 1.5748 inches and a maximum diameter of 1.9685 inches. It is suited to both production and job-shop environments where small-bore grooving and parting are common operations. The left-hand cutting direction makes it appropriate for specific spindle orientations and toolpost configurations. Typical installers include CNC machinists and tooling setup technicians working with turning centers equipped for modular grip tooling systems.
