Iscar 2801897 Indexable Boring Bar Left Hand Gehi

Product Description

The ISCAR 2801897 is a left-hand indexable boring bar in the Cut Grip series, designed for grooving, parting, and turning operations on CNC lathes and machining centers. Built with a steel body, it accepts GE.I and GEHI inserts secured by a clamp-style holding method. The 12mm shank diameter and 150mm overall length suit tight-bore applications, with a 15mm minimum bore diameter and 6mm maximum bore depth. Through-coolant capability, via a 6mm coolant hole, keeps cutting temperatures in check and aids chip evacuation during interrupted cuts or difficult materials.

This boring bar is suited for precision internal grooving and parting on small-bore workpieces in production turning environments. The left-hand cutting direction makes it appropriate for specific spindle orientations or gang-tool setups where a right-hand bar would interfere. Machinists and tooling engineers working with sliding-headstock lathes, sub-spindle operations, or Swiss-style turning centers will find this geometry useful. The through-coolant feature supports higher cutting speeds and extended insert life in ferrous and non-ferrous applications.

Key Features

• Left-hand cutting direction for sub-spindle and specific gang-tool configurations
• Through-coolant design with 6mm coolant hole for chip control and thermal management
• Clamp-style insert holding for rigid, repeatable insert seating
• Compatible with GE.I and GEHI insert styles for application flexibility
• Conforms to ISO 13399 tooling data standards for CAM and presetter integration
• Steel body construction for durability in production turning environments

Compatibility

Accepts GE.I and GEHI series inserts. Designed as an OEM-style replacement or production tooling option for lathes and turning centers requiring a left-hand GEHI-style indexable boring bar with a 12mm shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered off and all axes at rest. Ensure the shank bore of the toolholder block or turret is clean and free of debris before seating the 12mm shank. Connect through-coolant supply lines per the machine tool manufacturer specifications before resuming operation. Follow ISO 13399 data guidelines when configuring tool offsets in the CAM system or tool presetter.
