Sandvik Coromant 5764649 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5764649 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC lathes and machining centers. With a 32 mm (1.2598 inches) bore diameter and a 21 mm (0.8268 inches) bore depth, this adapter provides a rigid, accurate connection between the modular boring bar head and the machine spindle or tool holder body. The 134.40 mm (5.2913 inches) body length accommodates reach requirements in typical internal boring setups. Integrated internal coolant delivery directs cutting fluid directly to the cutting zone, supporting chip evacuation and tool life in demanding bore finishing applications. Machinists and tooling technicians install this adapter as part of a modular boring system.

This adapter is suited for use in modular boring bar assemblies on CNC turning centers and machining centers where precise bore sizing and surface finish are required. The 1X1 connection size interfaces with compatible Sandvik Coromant modular tooling components. Internal coolant capability makes it appropriate for deep bore applications and for materials that require high coolant pressure at the cutting edge. The screw thread lock mechanism, with a lock screw size of 5.49 inches, secures the modular connection under cutting loads. Typical applications include finish boring of housings, sleeves, and bores in automotive and general machining environments.
