Iscar 2850105 Indexable Grooving Toolholder External Rh

Product Description

The ISCAR 2850105 is an external, right-hand indexable grooving toolholder designed for precision grooving operations on CNC lathes and turning centers. Built to the TGD style within the Top Grip series, it accepts TGMF 3.. inserts secured by a clamp-type holding method. The toolholder handles groove widths from 0.118 inches to 0.125 inches with a maximum depth of cut of 0.29 inches. Overall length is 5 inches with a square shank measuring 0.75 inches by 0.75 inches. This tool is intended for machinists and CNC operators performing external grooving, parting, and recessing work in a production or job-shop environment.

The 2850105 is suited for external grooving applications in both high-volume production and precision job-shop turning. It is configured for right-hand cutting direction, making it compatible with conventional lathe setups where the tool feeds from right to left. The TGD toolholder style and Top Grip series are engineered for rigid insert clamping and repeatable positioning, supporting consistent groove geometry across multiple insert changes. This holder does not include coolant-through capability, so external coolant delivery should be planned accordingly.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the toolholder. Seat the shank fully and evenly in the tool post or turret block, and verify insert clamping is secure before running the spindle. Consult the machine tool manufacturer's specifications for proper torque and clamping procedures applicable to the tool post style in use.
