Iscar 2301526 Grooving Cutoff Toolholder Left Hand

Product Description

The ISCAR 2301526 is an indexable grooving and cut-off toolholder designed for precision groove machining on CNC lathes and turning centers. It features a DGT-style holder with a clamp-type insert holding method, accepting DG. 14.. series inserts from the Do Grip line. The shank measures 0.375 inches in height and 0.375 inches in width, with an overall length of 4.7 inches and a shank length of 3.99 inches. This left-hand toolholder is intended for machinists and tooling specialists working with narrow groove widths, specifically 0.055 inches. It conforms to ISO 13399 tooling data standards.

This toolholder is suited for grooving and cut-off operations in production turning environments, including both light and medium-duty applications where precise, repeatable groove width control is required. The left-hand orientation makes it appropriate for specific spindle or turret configurations where right-hand holders are not usable. It is used by machinists on manual and CNC turning equipment requiring narrow-groove insert tooling.

Installation Notes

Installation is performed by qualified machinists during tooling setup on turning centers or lathes. The machine spindle should be powered down and the turret or toolpost locked before mounting or removing the holder. Confirm insert seating and clamp torque per the insert manufacturer's tooling assembly guidelines before resuming cuts. Do not exceed the recommended depth of cut or feed rate for the installed insert grade.
