Iscar 6412014 Boring Chamfering Profiling Bar

Product Description

The ISCAR 6412014 is a micrograin solid carbide boring, chamfering, and profiling bar designed for precision internal machining operations at very small diameters. It accepts a minimum bore diameter of 1.50 mm (0.0590 inches) and a maximum bore depth of 0.10 mm (0.0040 inches), making it suited for tight-tolerance micro-boring work. The right-hand cutting direction and 4.00 mm shank diameter provide stable tool engagement in compact toolholding setups. Micrograin carbide construction delivers fine grain uniformity, supporting consistent edge integrity and extended tool life in demanding small-bore applications. Qualified machinists and CNC tooling specialists are the primary installers.

This bar is intended for use in precision CNC turning centers, Swiss-type lathes, and micro-machining setups where small internal bore diameters require accurate chamfering, profiling, or boring passes. The compact 19.00 mm overall length and 0.05 mm corner radius make it well matched to fine finishing work in components such as medical parts, watch components, miniature hydraulic fittings, and similarly tight-tolerance workpieces requiring controlled interior geometry.

Key Features

• Micrograin solid carbide construction for fine edge retention and wear resistance
• Minimum bore diameter of 1.50 mm enables operation in extremely small internal features
• Right-hand cutting direction for standard CNC turning and boring applications
• 0.05 mm corner radius supports controlled surface finish in profiling and chamfering passes
• 4.00 mm shank diameter for use with compatible micro-toolholding systems
• 19.00 mm overall length provides a compact footprint for confined machining environments

Compatibility

Designed as an OEM-style replacement or direct-fit boring bar for precision CNC turning and micro-machining toolholding systems accepting a 4.00 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before changing or setting tooling. Verify shank seating and runout with a dial indicator before commencing cuts. Follow the machine tool manufacturer guidelines for tool projection length and clamping torque appropriate to 4.00 mm shank toolholders.
