Sandvik Coromant 5726386 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5726386 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC machining centers and lathes. It features a 0.2756 inch (7.00 mm) bore diameter with a bore depth of 0.5512 inches (14.00 mm), and a 3/4 inch body diameter with a body length of 4.3307 inches. The adapter uses a screw thread lock mechanism and incorporates an internal coolant delivery channel to direct coolant to the cutting zone, extending tool life and improving chip evacuation during deep-bore or tight-tolerance work. Machinists and CNC tooling specialists install this adapter as part of a modular tooling assembly.

This adapter is suited for use in modular boring bar systems on CNC turning centers and machining centers where quick tool changes and repeatable runout accuracy are required. The 3/4 inch connection size makes it compatible with standard modular boring bar bodies of matching interface size. Internal coolant delivery supports high-speed cutting in difficult-to-machine materials where heat and chip buildup at the bore are primary concerns. The 0.5512 inch bore depth accommodates small-diameter boring bar shanks in compact modular setups.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before installing or removing modular adapters. Ensure mating surfaces are clean and free of chips or burrs before assembly to maintain runout accuracy. Tighten the lock screw to the tool system manufacturer's specification using the appropriate hex key or driver.
