Iscar 2301921 Tang-grip Indexable Cutoff Blade

Product Description

The ISCAR 2301921 is a single-end, neutral-cutting indexable cutoff and grooving blade from the Tang-Grip series. It measures 22.2 mm high, 3.4 mm wide, and 150 mm in overall length, with a 3.7 mm insert width and a cutting height of 22.4 mm. The blade uses a clamp-style insert holding method and accepts TAG-series inserts in a range of styles and geometries. Designed for rigidity and repeatability in high-production environments, this blade is suited for grooving, parting, and turning operations on CNC lathes and turning centers. It conforms to ISO 13399 tooling data standards. Machinists and toolroom technicians working with carbide insert tooling will find this a direct-fit Tang-Grip replacement.

This blade is intended for grooving, parting, and turning applications on workpieces up to 3.15 inches in maximum diameter. The Tang-Grip platform is widely used on CNC turning centers in both production and job-shop environments. It accommodates a range of insert widths from 3.70 mm minimum to 4.50 mm maximum, giving operators flexibility when selecting insert geometry for specific materials or surface finish requirements. Compatible insert styles include neutral, right-hand, and left-hand TAG configurations across multiple chipbreaker geometries.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians on CNC lathes and turning centers. Power down and lock out the machine spindle before seating or indexing inserts. Use the appropriate torque wrench and ISCAR clamping hardware specified for the Tang-Grip system — do not substitute non-OEM clamping screws or shims. Verify insert seating and blade alignment before resuming cutting operations.
