Iscar 4550317 Indexable Boring Cartridge Itsbore

Product Description

The ISCAR 4550317 is an indexable boring cartridge designed for precision internal boring operations on CNC machining centers and boring mills. Built to the ItsBore system, this cartridge accepts CCMT and CCGT style inserts and is configured for right-hand cutting. It carries a minimum bore diameter of 3.5433 inches (90.00 mm) and an overall length of 2.7756 inches (70.50 mm). The back-of-bar to cutting edge distance measures 1.0512 inches. Machinists and tooling technicians install this cartridge as part of a modular boring head assembly, allowing quick insert indexing without removing the boring bar from the spindle.

This cartridge is suited for production boring of medium-to-large diameter bores in steel, cast iron, and aluminum workpieces. It is compatible with BHR MB and TCH AL boring head systems and uses the IHCR toolholder style. Typical applications include finish boring of housings, flanges, and bearing bores where tight diameter tolerances and repeatable positioning are required. The cartridge is packaged individually and is intended for use by qualified tooling technicians and machinists in industrial manufacturing environments.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before mounting or adjusting the cartridge assembly. Use calibrated torque tools and follow the boring head manufacturer's assembly procedure when seating the cartridge. Verify bore diameter and runout with an appropriate gauging instrument before resuming production cuts.
