Sandvik Coromant 5728995 Boring Bar Modular Adapter 0.75 in

Product Description

The SANDVIK COROMANT 5728995 is a boring bar modular adapter designed for use in CNC turning and boring operations requiring precise internal tooling connections. This adapter features a 0.75 inch bore diameter and a 60 mm (2.3622 inch) bore depth, making it compatible with C5 connection-size tooling systems. The body measures 1.9685 inches in diameter and 2.3622 inches in length. An internal coolant channel directs cutting fluid directly to the cutting zone, reducing heat buildup and extending tool life. The screw thread lock with a lock screw size of 2.45 inches provides secure, repeatable clamping of boring bar shanks. Installed by machinists and tooling specialists in production shop environments.

This modular adapter is suited for precision boring applications in both production and job-shop settings. It is used when a C5 modular connection is required between a boring bar and a machine spindle or turret toolholder. The internal coolant design makes it appropriate for high-speed machining of tough materials where flood or through-spindle coolant delivery is part of the process. Typical installation scenarios include CNC lathe turrets and machining center spindles where modular tooling systems are already in use.

Key Features

• 0.75 inch bore diameter for standard boring bar shank acceptance
• 60 mm (2.3622 inch) bore depth for extended shank engagement
• C5 modular connection size for compatibility with C5 tooling system interfaces
• Internal coolant channel routes cutting fluid directly to the cutting zone
• Screw thread lock at 2.45 inch lock screw size for secure, repeatable clamping
• 1.9685 inch body diameter fits standard modular toolholder body envelopes

Compatibility

Designed for use with C5 modular tooling system interfaces. The manufacturer part number C5-131-00060-750 identifies this as a C5-series modular adapter. Specific machine or toolholder compatibility should be confirmed against your tooling system documentation prior to ordering.

Installation Notes

Installation and removal should be performed by a qualified machinist or tooling specialist with the machine spindle fully stopped and all motion axes locked out per facility lockout/tagout procedures. Use the specified torque tool for the screw thread lock fastener to ensure consistent clamping force without damaging the adapter bore. Verify coolant port alignment with the machine or toolholder coolant supply before final assembly. Inspect the bore and mating shank for burrs or contamination before each installation.
