Iscar 3600808 Indexable Boring Bar A-mcln Right Hand

Product Description

The ISCAR 3600808 is a right-hand A-MCLN indexable boring bar designed for internal turning and boring operations on CNC lathes and turning centers. It accepts CN.. 43.. series inserts in a diamond shape with a 1/2-inch inscribed circle, held in place by a clamp-style insert retention system. The bar has a 1-inch shank diameter, a 12-inch overall length, and supports a minimum bore diameter of 1-13/32 inches with a maximum bore depth of 4 inches. A through-coolant channel delivers cutting fluid directly to the insert tip, supporting tool life and chip evacuation in deep-bore applications. The negative rake geometry and -5 degree lead angle are suited to stable, productive metal removal in steel and similar workpiece materials.

This boring bar is intended for shop environments where internal diameter finishing and semi-finishing are performed on lathes equipped with coolant-through tooling capability. The 12-inch OAL provides reach for moderate-depth bores while the 1-inch shank keeps the bar compatible with standard static or live tool holders used in production turning. It is part of ISCAR's Isoturn series and is cataloged under the A-MCLNR/L 16-4 designation. The bar is appropriate for job shop and production machine shops running steel and similar materials where consistent insert indexing and coolant delivery are required.

Key Features

• Clamp-style insert holding for repeatable indexing with CN.. 43.. diamond inserts, 1/2-inch inscribed circle
• Steel shank construction with 1-inch diameter for use in standard boring bar holders
• Minimum bore diameter of 1-13/32 inches and maximum bore depth of 4 inches on a 12-inch OAL bar
• Conforms to ISO 13399 tooling data standards for compatibility with CAM and presetter systems

Compatibility

Accepts CN.. 43.. series diamond inserts with a 1/2-inch inscribed circle and compatible insert size code 43. Insert holding method is clamp-style. This bar is part of the ISCAR Isoturn series and is referenced under manufacturer designation A-MCLNR/L 16-4.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and all axes are at a safe home position before mounting or indexing the bar. The shank must be clamped securely in a boring bar holder sized for a 1-inch diameter shank with adequate projection to reach the required bore depth. Verify coolant-through passages are clear and that the machine's coolant-through spindle pressure is within the tool system's operating range before beginning a cut.
