Sandvik Coromant 5728999 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5728999 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC machining centers and turning equipment. With a 1.0000 inch bore diameter and a C5 connection size, this adapter interfaces with compatible modular tooling systems to extend reach or adapt between different tool body standards. The bore depth measures 70.00 mm (2.7559 inches) and the body diameter is 50.00 mm (1.9685 inches). An internal coolant channel directs cutting fluid directly to the cutting zone, improving chip evacuation and extending tool life in demanding applications. Installation and changeover are secured via a screw thread lock design. This component is handled by tooling specialists and CNC setup technicians.

This modular adapter is suited for internal boring operations in both production and job-shop environments where modular tooling systems are in use. The C5 connection makes it compatible with C5-standard modular boring and turning systems. Applications include precision bores in steel, cast iron, and similar materials where coolant delivery and rigid clamping are critical to achieving tight tolerances. It is packaged individually and sold as a single unit.

Key Features

• 1.0000 inch bore diameter for precise fit within compatible modular tool systems
• C5 connection size for standardized modular tooling interface
• Internal coolant channel for direct coolant delivery to the cutting zone
• 70.00 mm (2.7559 inch) bore depth provides extended reach for deep-bore applications
• Screw thread lock secures adapter engagement and resists vibration during cutting
• Body diameter of 50.00 mm (1.9685 inches) for clearance-conscious setups

Compatibility

Designed for use with C5-standard modular boring bar and turning tooling systems. Refer to the manufacturer part number C5-131-00070-1000 when cross-referencing against system component catalogs or machine tool documentation.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machinist. Ensure the machine spindle is fully stopped and the control is in a safe state before mounting or removing modular tooling components. Verify that mating surfaces are clean and free of chips or debris before seating the adapter. Torque the lock screw according to the tooling system manufacturer specifications; do not use impact tools on precision modular connections.
