Sandvik Coromant 5727709 Boring Bar Modular Adapter 1 in

Product Description

The SANDVIK COROMANT 5727709 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC lathes and machining centers. It accepts a 1-inch bore diameter and delivers a 91-millimeter (3.5827 inches) bore depth, making it suitable for medium-depth internal work. The adapter uses a C4 connection size and features an internal coolant path to direct cutting fluid directly to the cutting zone, reducing heat and improving chip evacuation. The body measures 40 millimeters (1.5748 inches) in diameter and 91 millimeters in length. Installation is handled by machinists and tooling specialists in production and job-shop environments.

This modular adapter is used in CNC turning and boring applications where a rigid, repeatable toolholder interface is required. It is suited for both light and moderate stock-removal passes on internal bores in ferrous and non-ferrous materials. The lock screw interface is compatible with lock screw size 3214 010-459, providing secure clamping at the modular joint. Internal coolant delivery makes this adapter well-suited for deep-bore applications where through-spindle coolant is available. It is typically deployed in production turning cells, aerospace machining, and precision component manufacturing.

Key Features

• 1-inch bore diameter with 91-millimeter (3.5827-inch) bore depth for medium-depth internal operations
• C4 modular connection for repeatable tool changes and accurate positioning
• Internal coolant path directs cutting fluid to the cutting zone for improved tool life and chip control
• Body diameter of 40 millimeters (1.5748 inches) provides rigidity in the adapter-to-spindle interface
• Lock screw compatibility with 3214 010-459 ensures secure mechanical clamping at the joint
• Compact body length of 91 millimeters supports minimal overhang in the toolholder stack

Compatibility

Compatible with C4 modular tooling systems. Lock screw compatibility listed for 3214 010-459. Consult SANDVIK COROMANT tooling system documentation to confirm fitment with specific turret or spindle configurations before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before mounting or removing any modular tooling components. Confirm that mating surfaces on both the adapter and the spindle or turret are clean and free of chips before assembly. Follow the machine tool manufacturer and SANDVIK COROMANT torque and clamping procedures as specified in the applicable product documentation.
