Sandvik Coromant 5726640 Boring Bar Solid Carbide Tialn

Product Description

The SANDVIK COROMANT 5726640 is a solid carbide boring bar designed for precision internal diameter machining in metalworking and machining center applications. Built from 1025 solid carbide stock and finished with a TiAlN/TiN coating, this boring bar delivers thermal resistance and wear performance suited to demanding bore finishing work. The right-hand cut geometry establishes consistent chip flow and surface finish control. Minimum bore diameter is 6.2mm, maximum bore depth is 15mm, shank diameter is 6mm, and overall length is 37.3mm. Machinists and toolroom technicians select this bar for small-bore applications where rigidity and coating durability matter.

This boring bar is intended for use in CNC machining centers, turning centers, and manual lathes equipped with compatible tool holders accepting a 6mm shank. It is well suited to small-diameter bore finishing, through-bore operations, and blind-bore applications within its stated depth capacity of 15mm. The TiAlN/TiN finish makes it appropriate for dry or near-dry cutting conditions in ferrous and non-ferrous materials. Typical users include production machinists, toolroom technicians, and precision job shop operators working with tight bore tolerances.

Key Features

• 1025 solid carbide construction for maximum rigidity in small-bore applications
• TiAlN/TiN finish provides thermal and wear resistance for extended tool life
• Right-hand cut geometry for consistent chip evacuation and surface finish
• 6.2mm minimum bore diameter supports precision small-bore machining
• 6mm shank diameter for broad toolholder compatibility
• Compact 37.3mm overall length minimizes overhang and deflection

Compatibility

Designed as an OEM-style boring bar for use in toolholders and boring systems accepting a 6mm round shank, suitable for CNC and manual machine tool platforms capable of accommodating the stated shank and overall length dimensions.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool builder guidelines for tool clamping and runout verification. Secure the shank fully within the toolholder to the manufacturer-recommended engagement depth before operation, and verify bore alignment before taking cuts. Always power down and lock out the machine spindle before changing or adjusting tooling. Do not exceed the stated maximum bore depth of 15mm to avoid tool deflection or breakage.
