Iscar 6402387 Boring Bar Solid Carbide Right Hand

Product Description

The ISCAR 6402387 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and turning centers. It features a right-hand cutting direction and a minimum bore diameter of 0.2362 inches (6.00 mm), making it well suited for small-bore finish and semi-finish turning. The overall length is 1.5748 inches (40.00 mm), with a maximum bore depth of 1.5750 inches. The shank diameter is 6.00 mm. A TiCN and TiN finish coating is applied to the cutting surface, and the bar is manufactured to ISCAR grade IC228, which is engineered for consistent tool life in steel and cast iron applications.

This boring bar is used in precision machining environments where tight tolerances on small internal diameters are required. Typical applications include finish boring of through-holes and blind bores in ferrous and non-ferrous workpieces on production turning equipment. The compact overall length suits short-reach setups where rigidity and minimal deflection are critical. Machinists and CNC operators in job shops, production facilities, and toolroom environments install this type of tooling as a direct replacement or as part of a new tooling setup.

Key Features

• Solid carbide construction for maximum rigidity in small-diameter boring applications
• Right-hand cutting direction for standard lathe and turning center setups
• Minimum bore diameter of 0.2362 inches (6.00 mm) enables small-bore precision work
• TiCN and TiN dual-layer coating improves wear resistance and surface finish
• ISCAR grade IC228 formulation suited for steel and cast iron cutting conditions
• Compact 1.5748-inch overall length reduces overhang and vibration risk

Compatibility

Designed as an OEM-style replacement or new-installation boring bar compatible with tool holders and boring systems accepting a 6.00 mm shank diameter in right-hand turning configurations.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be fully stopped and the control placed in an estop or lockout-tagout state before changing or seating the boring bar. Secure the shank firmly in the tool holder to the holder manufacturer's specified clamping torque using appropriate hex or torque wrenches. Verify runout and bore diameter with an air gauge or bore micrometer before committing to a production run.
