Sandvik Coromant 5727605 Indexable Boring Bar 1-1/2 in

Product Description

The SANDVIK COROMANT 5727605 is a steel indexable boring bar from the T-Max P series, designed for precision internal machining on CNC lathes and turning centers. Built to the A-DDUN toolholder style, it accepts a single DNMG 442 insert secured by a wedge clamping method. The bar features a 1 inch shank diameter and a 12 inch overall length, with a minimum bore diameter of 1.5 inches. The negative rake geometry and -6 degree lead angle make it well suited for stable, controlled cuts in a range of workpiece materials. Coolant-through capability supports chip evacuation and tool life in demanding applications.

This boring bar is used in production and job-shop turning operations where internal diameter work requires rigidity and insert security. Suitable for boring, profiling, and turning operations, it handles right-hand cutting configurations. The 12 inch overall length accommodates deeper bores where reach and bar stiffness are both critical. Machinists and CNC operators working with medium-to-large diameter bores on steel, cast iron, and similar materials will find this toolholder a direct fit into standard turning center setups that run DNMG 442 geometry inserts.

Key Features

• Wedge insert clamping for secure seating of DNMG 442 inserts under interrupted and continuous cut conditions
• Coolant-through design delivers cutting fluid directly to the cutting zone for improved chip control and insert life
• Negative rake, -6 degree lead angle geometry provides stable cutting forces and edge protection
• Multi-use toolholder supports boring, profiling, and turning without changeover
• 1 inch shank diameter and 12 inch OAL provide reach and rigidity for deeper internal features
• Center to cutting edge of 0.75 inches allows accurate bore diameter targeting

Compatibility

Compatible with DNMG 442 inserts. Insert inscribed circle is 0.5 inches (12.70 mm) and insert thickness is 0.25 inches. Toolholder style is A-DDUN, right hand. Part of the SANDVIK COROMANT T-Max P series. Catalog reference: A16T-DDUNR 4.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. The machine spindle must be locked and all axes brought to a safe position before mounting or indexing the insert. Confirm the shank is fully seated and clamping screws are torqued per the machine tool manufacturer's specifications. Verify coolant-through passages are clear and the supply line is properly connected before resuming cutting operations.
