Iscar 6405296 Chamfering Boring Bar Solid Carbide

Product Description

The ISCAR 6405296 is a solid carbide chamfering boring bar designed for internal chamfering operations in precision machining applications. Built from submicron-grade carbide with a TiAlN and TiN finish coating, it delivers consistent edge integrity at small bore diameters. The bar accepts a minimum bore diameter of 0.1969 inches and reaches a maximum bore depth of 0.748 inches, making it well suited for tight, shallow internal features. At 1.378 inches overall length with a 5.00 mm shank diameter, this is a compact tooling solution. The 20-degree bar end angle and 0.006-inch corner radius support clean chamfer geometry. Manufacturer grade IC908 indicates suitability for demanding cutting conditions. Right-hand cut configuration is standard.

This chamfering boring bar is used in CNC turning and boring operations where small-diameter internal chamfers are required. It is appropriate for precision components in automotive, aerospace, medical, and general manufacturing environments. The submicron carbide construction and dual-layer TiAlN and TiN coating make it a dependable choice for production runs where tool life and dimensional repeatability are critical. Machinists and CNC operators working with bores starting at 5.00 mm will find this bar fits directly into standard toolholding systems accepting 5.00 mm shank diameters.

Key Features

• Submicron solid carbide construction for high wear resistance and edge stability
• TiAlN and TiN dual-layer coating for extended tool life in ferrous and non-ferrous materials
• Minimum bore diameter of 0.1969 inches (5.00 mm) for small-feature internal chamfering
• 20-degree bar end angle with 0.006-inch corner radius for defined chamfer geometry
• Right-hand cut direction, compatible with standard CNC turning setups
• Compact 1.378-inch overall length for close-clearance tooling situations

Compatibility

Designed as an OEM-style replacement and direct-fit boring bar for CNC turning centers and boring machines accepting a 5.00 mm shank diameter with right-hand cut internal toolholding.

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 a safe state before changing or setting tooling. Confirm shank seating and runout with a dial indicator before initiating a cut. Follow the machine tool manufacturer guidelines for tool projection, clamping torque on the toolholder, and recommended cutting parameters for carbide boring bars.
