Sandvik Coromant 5726632 Boring Bar Solid Carbide

Product Description

The SANDVIK COROMANT 5726632 is a solid carbide boring bar designed for internal diameter boring operations on CNC lathes and machining centers. Built from 1025 solid carbide stock, it features a TiAlN/TiN dual-layer coating that improves wear resistance and thermal stability during cutting. The bar has a 6mm shank diameter, a minimum bore diameter of 6.2mm, a maximum boring depth of 15mm, and an overall length of 37.3mm. The right-hand cut geometry suits standard spindle rotation setups. Machinists and tooling specialists use this bar for precision internal finishing and semi-finishing in tight-bore applications.

This boring bar is suited for small-diameter internal boring work in both production and job-shop environments. The compact 6mm shank fits standard tool holders and collet chucks commonly found on CNC turning centers and live-tool lathes. Its short overall length and limited bore depth make it most applicable to shallow, small-bore features in ferrous and non-ferrous workpieces. It is intended for use by CNC machinists and toolroom technicians working to close tolerances on precision turned components.

Key Features

• 1025 solid carbide construction provides rigidity and resistance to deflection in small-diameter bores
• TiAlN/TiN coating extends tool life and supports higher cutting speeds
• Right-hand cut geometry for standard CNC lathe spindle rotation
• 6mm shank diameter fits widely available collet and tool-holder systems
• Minimum bore diameter of 6.2mm enables access to very tight internal features
• Compact 37.3mm overall length reduces overhang and vibration risk

Compatibility

Designed as an OEM-style replacement boring bar for small-diameter internal turning applications requiring a 6mm shank and right-hand cut solid carbide tooling.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the control is in an emergency-stop or locked-out state before changing tooling. Seat the shank fully in the collet or tool holder and verify runout with a dial indicator before committing to a cut. Do not exceed the maximum boring depth of 15mm, as over-extension increases deflection and risk of tool breakage.
