Sandvik Coromant 5734199 Indexable Boring Bar Solid Carbide

Product Description

The SANDVIK COROMANT 5734199 is an indexable boring bar from the CoroTurn 111 series, designed for internal turning operations on CNC and manual lathes. Built from solid carbide, this right-hand boring bar accepts CPMT 06 02 04 inserts secured by a screw-clamping method. It delivers a minimum bore diameter of 0.4803 inches, a 3/8-inch shank diameter, and a 6-inch overall length. The positive rake geometry at 4 degrees combined with a -5 degree lead angle helps manage cutting forces in tight bore profiles. Coolant-through capability supports chip evacuation and tool life in production environments. Licensed machinists and CNC operators use this bar in precision boring and internal turning applications.

This boring bar is suited for close-tolerance internal turning on small-diameter bores in both production and job-shop settings. The CoroTurn 111 series targets applications where bore access is limited and insert indexability is required to maintain consistent surface finish and dimensional accuracy. The 0.4803-inch minimum bore diameter makes it appropriate for small-bore work on ferrous and non-ferrous materials. Its multi-use designation indicates suitability across a range of internal turning scenarios where a solid carbide shank provides the rigidity needed to minimize chatter.

Key Features

• Solid carbide shank for maximum rigidity in small-bore turning
• Accepts CPMT 06 02 04 inserts with screw-clamping retention
• Coolant-through design for improved chip evacuation and insert life
• Positive rake angle of 4 degrees reduces cutting forces
• -5 degree lead angle suited for profiling and shoulder work
• Right-hand cut orientation for standard lathe setups

Compatibility

Designed to accept CPMT 06 02 04 indexable inserts. Part of the SANDVIK COROMANT CoroTurn 111 series for internal turning applications.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and all energy is locked out before mounting or adjusting the boring bar. The shank must be clamped securely in the toolholder to the manufacturer-specified engagement depth to prevent pull-out during cutting. Verify insert seating and screw torque according to insert manufacturer guidelines before initiating a cut.
