Iscar 3606662 Indexable Boring Bar 2.13in Right Hand

Product Description

The ISCAR 3606662 is a right-hand indexable boring bar designed for internal turning operations in metal-cutting applications. Part of the Heliturn LD series, it features a steel shank with a 1.25-inch diameter and an overall length of 12 inches. The tool accepts CNMX 1207 series diamond-shaped inserts held by a clamp-style mechanism and delivers a negative rake angle of -13 degrees for controlled chip formation. Through-coolant capability directs fluid directly to the cutting zone, extending insert life and improving chip evacuation during deep-bore operations. Licensed machinists and CNC operators install this bar in lathe turrets or boring setups where consistent, repeatable internal diameter cutting is required.

This boring bar is suited for internal turning on CNC lathes and manual turning centers in both production and job-shop environments. It handles bore diameters starting at 2.13 inches with a maximum bore depth of 2 inches, making it appropriate for through-bore and blind-bore finishing and semi-finishing passes. The through-coolant channel supports high-speed cutting strategies where heat management is critical. The tool is intended for professional machinists working with ferrous and non-ferrous materials where tight tolerance bores are required.

Key Features

• Minimum bore diameter of 2.13 inches with a maximum bore depth of 2 inches
• Right-hand cutting direction with a negative rake angle of -13 degrees for stable chip control
• Through-coolant design for direct coolant delivery to the insert tip
• Clamp-style insert holding secures CNMX 1207 series diamond-shaped inserts
• 1.25-inch shank diameter and 12-inch overall length for rigid reach into deep bores
• Conforms to ISO 13399 tooling data standards for CAM and tool management integration

Compatibility

Compatible with CNMX 1207 series diamond-shaped inserts using the A-PCLN insert style. Designed for use in machine tool turrets and boring heads that accept a 1.25-inch round shank.

Installation Notes

Installation and setup should be performed by a qualified machinist. Ensure the lathe or machining center spindle is fully stopped and the machine is placed in a safe, locked-out state before mounting or removing the boring bar. Verify that the through-coolant port on the machine turret aligns with the shank coolant inlet before tightening. Follow machine tool manufacturer torque guidelines for toolholder clamping screws when securing the shank in the turret.
