Frequently Asked Questions

What is a REGAL CUTTING TOOLS extension tap used for?

A REGAL CUTTING TOOLS extension tap is used to cut internal threads in deep or hard-to-reach holes. The extended shank allows the tap to reach recessed areas where a standard tap cannot fit, making it ideal for maintenance, repair, and production work on industrial equipment.

This extension tap has a 5/8"-11 UNC thread size, H3 / 3B tolerance, 3 flutes, and a plug chamfer. It is made from high-speed steel (HSS) and is designed for threading blind or through holes. The manufacturer part number is 015157AS.
