Cleveland C64103 Pipe Tap 1"-11.5 NPT

The Cleveland C64103 is a high-speed steel pipe tap designed for cutting 1"-11.5 NPT threads in pipe and conduit. It features a semi-bottoming chamfer with five flutes and a bright uncoated finish for general-purpose threading applications.

Check thread specifications before ordering

Verify that your workpiece requires a 1"-11.5 NPT thread form and that the 75 percent thread drill size of 1.1406 in matches your available tooling. The tap has an overall length of 3 3/4 in with a thread length of 1 3/4 in and a right-hand cutting direction.

Suited for maintenance

This tap suits professionals creating or repairing tapered pipe threads in steel or iron piping systems. It is not intended for through-hole tapping in non-ferrous materials where a different flute geometry or coating would be required. Buyers needing a taper or plug chamfer style should select a different tap.

Questions about this item

Does the Cleveland C64103 pipe tap come with the 1.1406 in drill bit needed for the 75 percent thread depth?

The tap is sold individually; the 1.1406 in drill bit for 75 percent thread engagement is not included and must be purchased separately.

When should I choose the 5-flute semi-bottoming version over other tap styles?

Choose this 5-flute semi-bottoming tap for 1"-11.5 NPT threads when you need stronger cutting action and are threading to near the bottom of a blind hole.

What does the 1"-11.5 NPT size mean when cutting threads in my workshop?

It cuts a 1 inch nominal pipe thread with 11.5 threads per inch to the National Pipe Taper standard for pressure-tight joints.
