Sandvik Coromant 5937344 Indexable Boring Bar 6 in Oal

Product Description

The SANDVIK COROMANT 5937344 is a steel indexable boring bar in the CoroTurn 107 series, designed for internal boring and turning operations on CNC lathes and turning centers. The toolholder features a 0.5000-inch shank diameter, a 6.0000-inch overall length, and a minimum bore diameter of 0.5984 inches (15.20 mm). Clamping is handled by a single screw, securing one TCMT 21.51 insert at a neutral rake angle with a 0.0000-degree lead angle. Coolant-through capability supports chip evacuation and tool life in demanding cutting conditions. This is a right-hand-cut holder suitable for finish and semi-finish boring passes.

The A08M-STFCR 2 toolholder is suited for small-diameter internal boring and turning applications in both production and job-shop environments. Its steel construction and screw-clamping interface make it a reliable choice for machinists running tight-tolerance bores on mills or lathes equipped with appropriate tooling systems. The multi-use designation means this holder supports both boring and external turning setups, depending on fixturing. Installation is handled by qualified machinists or CNC operators working to programmed toolpath specifications.

Compatibility

Designed for use with TCMT 21.51 series inserts. The insert inscribed circle measures 0.2500 inches (6.35 mm) and insert thickness is 0.0938 inches. This holder is part of the Sandvik Coromant CoroTurn 107 system. Verify turret or toolblock compatibility with the 0.5000-inch shank diameter before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before changing or seating the toolholder. Secure the shank in the appropriate toolblock or turret station to the machine-tool manufacturer's specified clamping torque - do not estimate. Confirm insert seating and screw torque using the insert manufacturer's recommended tooling key before running a test cut.
