Sandvik Coromant 5726458 Boring Bar Solid Carbide

Product Description

The SANDVIK COROMANT 5726458 is a solid carbide boring bar designed for small-diameter internal turning and bore finishing operations. Built from 1025 solid carbide stock, it carries a TiAlN/TiN dual-layer coating that extends tool life in demanding cutting conditions. The bar handles a minimum bore diameter of 5.2mm and reaches a maximum depth of 15mm, making it well suited for tight, shallow bore applications on CNC lathes and machining centers. With a 5mm shank diameter and an overall length of 37.3mm, it fits compact tooling setups where clearance is limited. Installation and use fall within the scope of a qualified machinist or CNC tooling technician.

This boring bar is applied in precision machining environments where small internal diameters require a rigid, wear-resistant cutting tool. Its right-hand cut geometry suits standard spindle rotation on conventional CNC turning setups. Typical applications include finish boring, light material removal, and bore sizing on ferrous and non-ferrous workpieces in job shop and production machining settings. The compact shank and short overall length make it a practical choice for Swiss-style lathes, micro-turning centers, and small-bore toolholders where larger bars cannot reach or fit.

Key Features

• Minimum bore diameter of 5.2mm for small internal bore applications
• Maximum bore depth of 15mm supports shallow precision bores
• 1025 solid carbide construction provides rigidity and wear resistance
• TiAlN/TiN coating extends cutting edge life and reduces heat buildup
• Right-hand cut geometry for standard CNC turning spindle direction
• 5mm shank diameter fits compact and Swiss-style toolholders

Compatibility

Designed as an OEM-style solid carbide boring bar for use in 5mm bore toolholders on CNC lathes, turning centers, and Swiss-style machining systems requiring a minimum bore diameter of 5.2mm.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the toolholder is de-energized before inserting or changing the boring bar. Confirm proper shank clamping torque per the toolholder manufacturer specifications and verify tool overhang does not exceed recommended limits to prevent chatter. Follow applicable shop safety protocols and machine manufacturer guidelines during setup.
