Allied Machine and Engineering 2T-6SR Rotary Coolant Adapter

Product Description

The ALLIED MACHINE AND ENGINEERING 2T-6SR is a rotary coolant adapter engineered for use with indexable drilling and boring tools. It connects the coolant supply to rotating toolholders, allowing through-spindle or through-tool coolant delivery during machining operations. The adapter features a 0.5 NPT coolant port, a 2.25-inch inner diameter, and a 3.75-inch outer diameter. At 1.75 inches thick with an overall length of 1.75 inches, it is a compact, direct-fit component for T-A series tooling systems. The drive rod thread is 1/2 NC. It ships complete with O-rings, snap rings, and thrust washers included in the package.

This adapter is suited for CNC machining centers and drilling applications where pressurized coolant must be routed through the tool body to the cutting zone. The T-A series designation makes it appropriate for use in indexable spade drill and boring tool assemblies common in production and job-shop environments. Installation is typically performed by machinists or tooling setup technicians. The included sealing and retention hardware eliminates the need to source additional components at the time of installation.

Key Features

• 0.5 NPT coolant port for standard coolant line connection
• 2.25-inch ID and 3.75-inch OD for defined bore and flange fit
• 1/2 NC drive rod thread for positive rotational engagement
• 1.75-inch overall length compact profile for space-constrained spindle applications
• Includes O-rings, snap rings, and thrust washers — no separate hardware required
• Part of the T-A series system for indexable tooling compatibility

Compatibility

Designed for use with Allied Machine and Engineering T-A series indexable tooling systems. Verify spindle coolant port configuration, NPT thread engagement, and drive rod thread size against the target toolholder before installation.

Installation Notes

Installation is performed by qualified tooling technicians or machinists. Shut off all coolant flow and de-energize the machine spindle before fitting or removing the adapter. Inspect O-rings for damage before assembly and replace if any deformation or cracking is present. Confirm NPT thread engagement is wrench-tight without over-torquing, which can crack the adapter body or distort sealing surfaces.
