Iscar 2300842 Indexable Cutoff Toolholder Right Hand

Product Description

The ISCAR 2300842 is a right-hand indexable cutoff toolholder designed for grooving, parting, and turning operations on CNC lathes and turning centers. Built to the SGTF toolholder style, it accepts a range of GFN and GFR/L series inserts using a self-grip holding method that locks inserts securely without additional clamping hardware. The holder has a 0.625-inch square shank and handles workpieces up to 1.38 inches in diameter. Overall length is 4.5 inches. Compatible insert widths range from 0.106 inches minimum to 0.139 inches maximum. This toolholder is used by machinists and CNC lathe operators in production and job-shop environments.

The 2300842 is suited for light to medium-duty cutoff and grooving work on bar stock and turned components. Its compact head geometry — 0.625 inches head height and 0.75 inches head length — allows close-approach work and narrow clearance applications. The blade width of 0.094 inches supports minimal material loss on cutoff passes. Coolant-through capability is not available on this holder. It conforms to ISO 13399 tooling data standards, making it compatible with modern tool management and presetter software used in CNC environments.
