Sandvik Coromant 5726655 Boring Bar Solid Carbide Tialn/tin

Product Description

The SANDVIK COROMANT 5726655 is a solid carbide boring bar designed for precision internal turning and bore finishing operations on CNC and manual lathes. Built from 1025 solid carbide stock, it delivers the rigidity and vibration resistance needed for accurate, repeatable bore diameters in tight tolerances. The bar features a TiAlN/TiN finish that extends cutting edge life by resisting heat and wear at elevated cutting speeds. With a 6.2mm minimum bore diameter, a 6mm shank diameter, and a 37.3mm overall length, this tool is sized for small-bore work requiring fine surface finish and dimensional accuracy.

This boring bar is suited for small-diameter internal machining in ferrous and non-ferrous workpieces across job shop, production, and toolroom environments. The right-hand cut configuration makes it compatible with conventional lathe and machining center setups where the spindle rotates counterclockwise as viewed from the spindle nose. It handles bore depths up to 15mm, making it a practical choice for through and blind-bore finishing passes in components such as bushings, hydraulic bodies, and precision fittings.

Key Features

• 1025 solid carbide construction provides high stiffness and chatter resistance in small-bore applications
• TiAlN/TiN coating extends tool life by reducing heat buildup and flank wear at the cutting edge
• 6.2mm minimum bore diameter enables access to tight, small-diameter internal features
• Right-hand cut geometry suits standard lathe and machining center configurations
• 15mm maximum bore depth supports both through-bore and blind-bore finishing passes
• 6mm shank diameter fits standard small-bore toolholders and boring head systems

Compatibility

Designed as an OEM-style replacement boring bar for use in small-bore internal turning applications on CNC lathes and machining centers equipped with toolholders accepting a 6mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the toolholder is secured before inserting or removing the boring bar. Mount the bar with minimal overhang beyond the toolholder to reduce deflection and chatter during cutting. Verify shank clamping torque against the toolholder manufacturer's specifications before initiating a cut.
