Sandvik Coromant 5729267 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5729267 is a boring bar modular adapter designed for precision internal machining operations. It accepts a 1.5748-inch (40 mm) bore diameter and provides a 3.6221-inch (92 mm) bore depth, making it suitable for deep-bore applications where reach and rigidity are critical. The adapter features a C6 connection size and a 2.4803-inch (63 mm) body diameter. An integrated internal coolant path delivers cutting fluid directly to the cutting zone, extending tool life and improving chip evacuation. This component is installed by machinists and tooling specialists working with modular boring systems on CNC turning centers and machining cells.

This adapter fits into modular boring bar assemblies used in production and job-shop environments requiring repeatable, accurate internal diameter machining. The C6 interface supports quick tool changes without sacrificing runout accuracy. Internal coolant compatibility makes it well suited for deep-bore steel, cast iron, and alloy machining where flood coolant does not reach effectively. The lock screw interface is compatible with the 3212 010-358 lock screw, as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing modular tooling components. Verify that the mating C6 interface surfaces are clean and free of chips or debris before assembly. Follow the machine tool manufacturer and tooling manufacturer torque guidelines for lock screw engagement to maintain proper clamping force and runout specifications.
