Sandvik Coromant 5726696 Boring Bar Solid Carbide Tialn

Product Description

The SANDVIK COROMANT 5726696 is a solid carbide boring bar designed for small-diameter internal turning and boring operations on CNC lathes and machining centers. Built from 1025-grade solid carbide, it offers the rigidity and vibration resistance needed for tight-tolerance bore finishing. The TiAlN/TiN coating reduces friction and extends cutting edge life in ferrous and non-ferrous materials. With a 6.2mm minimum bore diameter, 15mm maximum boring depth, 6mm shank diameter, and 37.3mm overall length, this bar fits compact toolholding setups where reach and clearance are at a premium. Right-hand cut orientation suits standard lathe configurations. Machinists and CNC operators in production and job-shop environments rely on this style of bar for precision bore sizing.

This boring bar is suited for internal diameter finishing and semi-finishing passes on small bores in steel, cast iron, and similar workpiece materials. Its compact geometry makes it practical for Swiss-style lathes, gang-tooled CNC lathes, and small-bore turning centers where shank real estate is limited. The 6mm shank allows direct mounting in standard boring bar holders and quick-change tooling systems common to that class of machine. Applications include bore sizing on hydraulic valve bodies, pneumatic components, and precision mechanical assemblies requiring controlled surface finish and dimensional accuracy.

Key Features

• 1025 solid carbide construction provides rigidity and resistance to deflection in small-bore applications
• TiAlN/TiN coating extends tool life and reduces built-up edge in ferrous materials
• Right-hand cut orientation for standard lathe and turning center setups
• 6.2mm minimum bore diameter suits tight internal diameter work
• 15mm maximum boring depth with 37.3mm overall length for compact tooling setups
• 6mm shank diameter compatible with standard small-bore toolholders and quick-change systems

Compatibility

Designed as an OEM-style solid carbide boring bar for use in standard 6mm shank boring bar holders on CNC lathes, Swiss-style lathes, and small-bore turning centers. No specific machine model compatibility data was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the shank fully within the toolholder to the recommended engagement depth for the holder style in use, and ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state before any tool change. Verify bore diameter, depth, and runout with appropriate gauging before committing to finish passes. Do not exceed the maximum boring depth of 15mm, as extended overhang beyond rated depth increases deflection and reduces dimensional accuracy.
