CHICAGO-LATROBE Extension Tap: 1/8"-27 NPT, 4 Flute, Semi-Bottoming Chamfer, High Speed Steel (MPN 384524)

A CHICAGO-LATROBE extension tap is used to cut internal NPT 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 system maintenance.

The CHICAGO-LATROBE 384524 is a 1/8\"-27 NPT extension tap with 4 flutes, a semi-bottoming chamfer, and is made from high-speed steel. It is designed for threading pipe threads in steel, stainless steel, and other ferrous materials. The semi-bottoming chamfer allows threading close to the bottom of a blind hole.

Select an extension tap based on thread size (e.g., 1/8\"-27 NPT), material (high-speed steel for general use), chamfer type (semi-bottoming for blind holes), and reach length. For deep or offset holes, ensure the extension shank is long enough to clear obstructions. CHICAGO-LATROBE taps are a reliable choice for consistent thread quality.
