Iscar 2550088 Indexable Grooving Blade Right Hand Hgai

Product Description

The ISCAR 2550088 is a right-hand indexable grooving blade from the Heliface series, designed for grooving, parting, and turning operations on CNC lathes and turning centers. Built to HGAI blade style, it accepts indexable inserts that can be rotated or replaced without removing the blade body from the toolholder. The blade measures 2.1654 inches in overall length and 0.4020 inches in blade width. It delivers a maximum depth of cut of 0.3543 inches and handles a minimum groove width of 0.1181 inches. Machining technicians and toolroom professionals install this blade in compatible toolholders for precision OD grooving and cutoff work on small-diameter workpieces.

This blade is suited for turning and grooving applications on workpieces with a minimum diameter of 0.9843 inches and a maximum diameter of 1.3386 inches. It is well matched to production turning environments where tight groove tolerances and repeatable insert indexing are required. The Heliface series targets applications demanding consistent chip control and accurate groove geometry on small-bore work. Typical use cases include external grooving, parting-off, and contour turning on bar-fed CNC lathes in both job shop and production settings.

Installation Notes

Installation is performed by qualified machining technicians or toolroom personnel. Power down and lock out the machine before changing or seating the blade in the toolholder. Use calibrated torque wrenches and manufacturer-specified fasteners when securing the blade body; do not over-tighten clamping screws, as this can distort the blade seat. Verify insert seating, blade projection, and centerline height before resuming cutting operations.
