Sandvik Coromant 5728196 Boring Bar Modular Adapter C5

Product Description

The SANDVIK COROMANT 5728196 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC machining centers and turning centers. This adapter features a 0.625 inch bore diameter, a 59.99 mm (2.362 inch) bore depth, and a C5 connection size for secure modular tooling assembly. Internal coolant delivery channels direct cutting fluid directly to the cutting zone, reducing heat buildup and improving chip evacuation during deep bore operations. Licensed machinists and CNC tool setup technicians install this adapter as part of a modular boring bar system. The body diameter measures 1.9685 inches with a body length of 2.362 inches, and the unit weighs 1.75 pounds.

This modular adapter is suited for shops running modular boring bar assemblies where quick changeover and repeatable tool positioning are required. It is appropriate for both production and job-shop environments handling medium to large bore diameters. The C5 connection size is a standard modular interface used across a range of anti-vibration and steel boring bar shanks. The adapter pairs with compatible lock screw part number 5763381 per the manufacturer specification.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular boring bar assembly procedures. Ensure the machine spindle is fully stopped and all power is locked out before mounting or removing the adapter. Use the specified lock screw (5763381) and tighten to the torque value specified in the SANDVIK COROMANT tooling assembly documentation — do not estimate torque. Verify internal coolant passages are clear and aligned with the machine coolant supply before resuming cutting operations.
