Frequently Asked Questions

What is an OSG extension tap used for?

An OSG extension tap is used to cut internal threads in hard-to-reach or deep-hole applications. The extended shank allows threading in locations where a standard tap cannot reach, such as in engine blocks or deep bores. It is designed for #10-24 UNC threads in materials like steel and aluminum.

What are the specifications of the OSG #10-24 UNC extension tap?

This OSG extension tap is #10-24 UNC with a H3 / 2B-3B thread limit, 2-flute design, plug chamfer, and made from high-speed steel. The manufacturer part number is 1294600. It is a spiral-point extension tap for through-hole threading in deep or obstructed locations.

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

Select an OSG extension tap based on thread size, pitch, and reach required. For #10-24 UNC threads in deep holes, choose a plug chamfer for general-purpose threading. Ensure the tap's H3 / 2B-3B tolerance matches your desired thread class. Use proper cutting fluid and alignment to prevent breakage.
