Iscar 2800292 Indexable Boring Bar Left Hand Ghi

Product Description

The ISCAR 2800292 is a left-hand indexable boring bar from the Cut Grip series, designed for internal grooving, parting, profiling, threading, and turning operations on CNC lathes and machining centers. It accepts GI.. and GHI series inserts secured by a screw-clamping method, providing repeatable positioning and fast insert changes. The bar features a 0.75-inch shank diameter, a minimum bore diameter of 0.787 inches, a maximum bore depth of 1.5 inches, and an overall length of 8 inches. It is classified as a multi-use tool, making it a versatile addition to any turning setup where internal grooving and threading capability are required in a single holder.

This boring bar is suited for professional machinists and toolroom technicians working on small-bore internal operations in ferrous and non-ferrous materials. The left-hand cutting direction makes it appropriate for reverse-spindle or sub-spindle work, or applications requiring a left-hand tool path. Typical install scenarios include gang tooling setups, Swiss-style lathes, and secondary spindle turrets. The GHI toolholder style and GI.. insert compatibility place this bar within a well-established insert platform used across production and job-shop environments. This part ships as a single-piece unit.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine powered down and in an e-stop or locked-out state per applicable facility lockout/tagout procedures. The shank should be clamped securely in a boring bar holder or turret block to the required engagement depth before operation. Verify insert seating and screw torque to the insert manufacturer specification before initiating a cutting cycle. Coolant-through is not supported on this holder; use external coolant delivery where required.
