Sandvik Coromant 5721710 Indexable Boring Bar Left Hand

Product Description

The SANDVIK COROMANT 5721710 is an indexable boring bar from the CoroTurn 107 series, designed for internal boring and turning operations on CNC lathes and turning centers. The toolholder features a 0.75 inch shank diameter, a 10 inch overall length, and a minimum bore diameter of 0.929 inches (23.60 mm). It is a left-hand configuration with a neutral rake angle and screw clamping to secure a single CCMT 32.52 insert. The steel body construction provides rigidity for precision internal machining. Machinists and CNC turning specialists install and use this toolholder in production and job-shop environments.

This boring bar suits internal diameter work on CNC turning centers where a left-hand cut orientation is required. The CoroTurn 107 series is intended for both boring and turning applications in a single toolholder platform. The center-to-cutting-edge dimension is 0.50 inches, and back-of-bar to cutting edge measures 10 inches. Coolant-through capability supports chip evacuation and tool life in deep-bore or high-feed applications. This toolholder accepts one CCMT 32.52 insert with a 0.375 inch inscribed circle and 0.156 inch thickness.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts or adjusting the toolholder. Use the correct torque wrench and insert screw driver specified for CCMT screw-clamp systems when seating the insert. Verify bore diameter clearance and overhang before running to minimize vibration and deflection.
