Iscar 2301890 Indexable Cutoff Blade Tang-grip

Product Description

The ISCAR 2301890 is a single-end neutral indexable cutoff and grooving blade from the Tang-Grip series, designed for precision parting, grooving, and turning operations on CNC lathes and turning centers. The blade measures 45mm in height, 2.5mm in width, and 225mm in overall length (OAL). It accepts TAG-style inserts with a 2.8mm minimum insert width and supports insert widths up to 3.5mm. The clamp-style insert holding method provides secure indexing under high cutting loads. Blade style is TGFH and the part conforms to ISO 13399 standards. Licensed machinists and CNC operators working in production or job-shop environments are the primary users.

This blade is suited for external grooving, parting, and turning applications on workpieces up to 6.3 inches in maximum diameter. It is compatible with SGTBU and SGTBN tool block styles and is intended for use in rigid tooling setups on manual or CNC turning equipment. The cutting height is 38.1mm (1.5 inches), making it appropriate for moderate-depth parting and grooving passes. It is a direct-fit replacement for applications requiring the TGFH 45-3 catalog designation.
