Frequently Asked Questions

What is a CHICAGO-LATROBE extension tap used for?

A CHICAGO-LATROBE extension tap is used to cut internal NPTF threads in hard-to-reach or deep-hole applications. The extended shank allows threading in confined spaces, such as pipe fittings or manifolds, where standard taps cannot reach. It is common in plumbing, hydraulic, and pneumatic systems.

What are the specifications of the CHICAGO-LATROBE 386129 extension tap?

The CHICAGO-LATROBE 386129 extension tap has a 1/8"-27 NPTF thread size, 4 flutes, and a semi-bottoming chamfer. It is designed for threading tapered pipe threads in steel, stainless steel, and other metals. The extension shank provides reach for deep or obstructed holes.

How to select the right extension tap for NPTF threads?

Select an extension tap like the CHICAGO-LATROBE 386129 by matching thread size (1/8"-27 NPTF), chamfer type (semi-bottoming for blind holes), and flute count (4 flutes for chip clearance). Ensure the shank length reaches the threading depth. Use cutting fluid for steel and reduce speed for harder materials.
