Iscar 2550075 Indexable Grooving Blade Right Hand

Product Description

The ISCAR 2550075 is a right-hand indexable grooving blade designed for precision grooving, parting, and turning operations on CNC lathes and turning centers. Part of the ISCAR Heliface series, this blade measures 2.6969 inches in overall length with a blade height of 1.26 inches and a blade width of 0.204 inches. It accepts a broad range of indexable inserts, making it a versatile toolholder for shops running varied grooving applications. Machinists and toolroom technicians install this blade into compatible toolholding systems to achieve consistent groove geometry with repeatable insert indexing. The blade conforms to ISO 13399 cutting tool standards.

This grooving blade is suited for external grooving, parting, and contour turning on workpieces with a minimum diameter of 1.8898 inches and a maximum diameter of 2.3622 inches. The maximum depth of cut is 0.7874 inches, supporting moderate to deep groove profiles. It is intended for use in production turning environments - both job shop and high-volume - where right-hand cutting direction and secure insert clamping are required. The Heliface series design is optimized for stable clamping and minimal blade deflection during interrupted or continuous grooving cuts.
