CHICAGO-LATROBE Spiral-Point Extension Taps.

Frequently Asked Questions

What is a CHICAGO-LATROBE extension tap used for?

A CHICAGO-LATROBE extension tap is used to cut internal threads in deep or hard-to-reach holes. The extended shank allows threading in recessed areas, such as engine blocks or hydraulic manifolds, where standard taps cannot reach. It is designed for UNC threads and works with most ferrous and non-ferrous materials.

What are the specifications of the CHICAGO-LATROBE extension tap MPN 313602?

The CHICAGO-LATROBE extension tap MPN 313602 has a thread size of 7/16"-14 UNC, an H11 tolerance, 3 flutes, and a plug chamfer. It is a spiral-point tap designed for through-hole threading. The extended shank provides reach for deep applications. These specs are from the manufacturer's technical data.

Where to buy CHICAGO-LATROBE extension taps worldwide?

How to select the right CHICAGO-LATROBE extension tap for a job?

To select the right CHICAGO-LATROBE extension tap, match the thread size (e.g., 7/16"-14 UNC), tolerance (H11), and chamfer type (plug) to your hole depth and material. For deep or blind holes, consider flute count and spiral point design. Always verify the tap's reach length against your workpiece geometry.
