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

Product Description

The ALLIED MACHINE AND ENGINEERING 2T-2SR is a rotary coolant adapter engineered for use with indexable drilling and boring tools. It provides a sealed coolant-through connection at the spindle interface, directing cutting fluid to the tool tip during deep-hole and high-feed operations. The adapter features a 1/8 NPT coolant port, a 0.75-inch inner diameter, and a 1.75-inch outer diameter, making it a compact and purpose-built component for precision metal-cutting applications. Installation requires a 5/16 NC drive rod thread connection. The kit includes O-rings, snap rings, and thrust washers, supplying the sealing hardware needed for a complete assembly. Machinists and tooling engineers working in production shops are the primary installers.

This adapter is designed for use with Allied Machine and Engineering T-A series indexable tools. It is suited for CNC machining centers and drill presses where coolant-through spindle capability is required. Typical applications include high-speed drilling in steel, cast iron, and other ferrous materials where heat management at the cutting edge directly affects tool life and hole quality. The 7/8-inch thickness keeps axial stack-up minimal within standard spindle assemblies.

Key Features

• 1/8 NPT coolant inlet port for standard coolant-through spindle connections
• 0.75-inch ID and 1.75-inch OD for compact fitment in T-A series tooling assemblies
• 5/16 NC drive rod thread for positive rotational engagement
• 7/8-inch thickness minimizes axial projection in the spindle stack
• Includes O-rings, snap rings, and thrust washers for complete sealing hardware

Compatibility

Designed for use with Allied Machine and Engineering T-A series indexable tooling systems requiring rotary coolant-through adapter connections.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the spindle fully de-energized and the machine in a locked-out, tagged-out state. Ensure all included O-rings and thrust washers are seated correctly before torquing the drive rod connection. Verify coolant system pressure is within the tool system rating before resuming operations. Consult the T-A series tooling documentation for assembly sequence and preload requirements.
