Iscar 6405286 Chamfering Boring Bar Submicron Solid Carbide

Product Description

The ISCAR 6405286 is a solid carbide chamfering boring bar engineered for precision internal chamfering operations on small-diameter bores. Built from submicron-grade carbide with a TiAlN and TiN finish coating, it delivers consistent edge integrity and wear resistance in demanding cutting applications. The bar features a right-hand cutting direction, a 20-degree bar end angle, and a 0.004 inch corner radius, making it suited for fine finishing passes in tight bore geometries. With an overall length of 0.9449 inches and a minimum bore diameter of 0.1378 inches, this tool is designed for machinists working in precision machining environments where bore access is restricted and dimensional accuracy is critical.

This chamfering boring bar is intended for use in CNC turning centers, boring mills, and similar machine tool setups requiring internal chamfer geometry on small bores. It handles a maximum bore depth of 0.3937 inches and is ground to ISCAR manufacturer grade IC908, a submicron carbide grade known for its toughness and performance in steel and stainless steel applications. It is typically installed by machinists, tool-and-die professionals, and precision parts manufacturers running production or prototype work on small-diameter components.

Key Features

• Submicron solid carbide construction for high edge strength and wear resistance
• TiAlN and TiN dual finish coating for extended tool life in ferrous materials
• Right-hand cut with 20-degree bar end angle for precise internal chamfering
• 0.004 inch corner radius for controlled edge geometry on finish passes
• Compact 0.9449 inch overall length suited for restricted-access bore applications
• ISCAR IC908 manufacturer grade for consistent performance in demanding cuts

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide boring bar for small-bore internal chamfering applications on CNC turning and boring equipment accepting a 4.00 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for boring bar setup and runout tolerance. Ensure the machine spindle and tool holder are fully de-energized and locked out before mounting or removing the bar. Verify shank seating and projection length against the specified bore depth before initiating a cut. Do not exceed the maximum bore depth rating of 0.3937 inches for this tool.
