Allied Machine 2T-3SR Rotary Coolant Adapter 1/8 Npt

Product Description

The ALLIED MACHINE AND ENGINEERING 2T-3SR is a rotary coolant adapter designed for use with indexable drilling tools in through-spindle coolant delivery systems. Measuring 1 inch inner diameter by 2-1/8 inches outer diameter, with an overall length of 1-1/8 inches, this adapter connects to the coolant supply via a 1/8 NPT port. The drive rod thread is 5/16 NC. It ships complete with o-rings, snap rings, and thrust washers, providing the hardware needed for a full installation. This part is suited for machine tool technicians and tooling setup personnel working with T-A series deep-hole drilling systems.

The 2T-3SR is used in machining centers and drilling applications where pressurized coolant must be delivered through a rotating spindle to the cutting zone. The T-A series designation places this adapter within ALLIED MACHINE AND ENGINEERING's established indexable drill platform. Typical installations involve CNC machining centers with through-spindle coolant capability, where consistent coolant flow to the drill tip is critical for chip evacuation and tool life. Tooling engineers and machine setup technicians are the primary installers.

Compatibility

Designed for use with the T-A series indexable drilling tool platform by ALLIED MACHINE AND ENGINEERING, where through-spindle coolant delivery is required.

Installation Notes

Installation is performed by qualified machine tool technicians or tooling setup personnel. Shut off spindle power and isolate coolant supply pressure before removing or installing any rotary coolant adapter. Verify that all included o-rings, snap rings, and thrust washers are properly seated before restoring coolant flow. Follow the machine tool manufacturer's torque and fitment guidelines for spindle interface components.
