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. Its extended length allows threading in applications where standard taps cannot reach, such as in engine blocks or hydraulic manifolds, across machining and industrial maintenance operations.

What are the specifications of the CHICAGO-LATROBE M16x2 extension tap?

This CHICAGO-LATROBE extension tap has a metric M16x2 thread, D11 size, 3 flutes, plug chamfer, and is made of high-speed steel. The manufacturer part number is 313554. It is designed for through-hole threading in steel and other materials requiring a spiral-point geometry.

How to select the right extension tap for deep hole threading?

Select an extension tap like this CHICAGO-LATROBE M16x2 model based on thread size, material, and hole depth. Use a plug chamfer for through holes and a spiral-point design to push chips forward. Ensure the tap length exceeds the hole depth by at least 1.5 times the thread diameter.
