Iscar 4550299 Indexable Boring Bar 6mm Min Bore

Product Description

The ISCAR 4550299 is an IHAXF-style indexable boring bar engineered for small-bore internal turning operations. With a minimum bore diameter of 6mm (0.2362 inches) and a maximum bore depth of 21mm (0.8268 inches), this tool handles tight-tolerance finish boring in confined bore profiles. The 16mm (0.6299-inch) shank diameter and 51mm (2.0079-inch) overall length keep the tool compact and rigid. Through-coolant delivery channels coolant directly to the cutting zone, reducing heat and improving chip evacuation. Insert retention is by screw clamp, providing repeatable seating of WCGT 0201 trigon-style inserts. Machinists and tool-and-die professionals working on CNC lathes and boring mills are the primary users of this bar.

This boring bar is suited for precision internal boring of small diameters in both production and job-shop environments. The IHAXF toolholder style is part of the Itsbore series, designed for bore diameters ranging from 6mm minimum up to 8mm maximum (0.3150 inches). It is applicable in operations requiring clean bore finishes where chip control and coolant access are critical, such as hydraulic valve bodies, small pneumatic cylinders, and precision mechanical housings. The screw-held trigon insert geometry supports controlled cutting forces appropriate for these bore sizes.

Key Features

• Minimum bore diameter of 6mm (0.2362 inches) with a maximum of 8mm (0.3150 inches)
• Maximum bore depth of 21mm (0.8268 inches) for reach into confined bores
• Through-coolant capability directs fluid to the cutting edge for heat management and chip flushing
• Screw-held insert clamping ensures consistent WCGT 0201 insert positioning and secure retention
• WCGT 0201 trigon insert compatibility - a widely available insert geometry in the Itsbore system
• Compliant with ISO 13399 tooling data standards for integration with CAM and tool management software

Compatibility

Designed for use with WCGT 0201 trigon-style inserts in IHAXF-series toolholders within the ISCAR Itsbore system. Compatible insert size code is 0201.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician familiar with indexable boring bar systems. Ensure the machine spindle is fully stopped and the tool turret or spindle is locked before mounting or indexing inserts. Verify through-coolant passages are clear and that coolant pressure is within the machine specification before running. Follow ISO 13399 tooling assembly guidelines and the machine tool manufacturer's torque recommendations for insert screws.
