WIDIA GTD Pipe and Conduit Thread Tap: 1/8"-27 NPTF, H3 / 3B, 5 Flute, Plug Chamfer (MPN 16103)

This WIDIA GTD interrupted-thread tap is designed for threading pipe and conduit in aluminum. It creates NPTF threads (1/8"-27) for leak-resistant joints in pneumatic, hydraulic, and plumbing systems. The plug chamfer and 5-flute design help clear chips in softer materials.

The WIDIA GTD 16103 is a 1/8"-27 NPTF interrupted-thread pipe tap with H3 / 3B tolerance, 5 flutes, and a plug chamfer. It is designed for threading aluminum and other non-ferrous materials. The interrupted-thread geometry reduces torque and improves chip evacuation.

For aluminum, choose a tap with interrupted threads (like this WIDIA GTD) to reduce galling and improve chip clearance. Verify the thread size (1/8"-27 NPTF), chamfer type (plug for through holes), and tolerance class (H3). Use cutting fluid designed for aluminum to extend tool life.
