Cleveland C64060 Pipe Tap for NPTF Threads

This Cleveland C64060 pipe tap cuts 1/8"-27 NPTF threads in pipe and conduit. The high-speed steel construction provides durability for threading ferrous and non-ferrous materials. A semi-bottoming chamfer allows threading close to the bottom of blind holes. Four flutes ensure efficient chip evacuation and a smooth thread finish for reliable sealing.

Upgrading from Worn or Incorrect Taps

Replace dull, damaged, or mismatched taps that produce leak-prone threads or stall in the workpiece. The jump is worth it when existing tooling fails to maintain the 75 percent thread depth required for dryseal NPTF connections. Sharp, correctly sized flutes restore threading speed and reduce the risk of tap breakage during operation.

Limits of NPTF Threading with Hand Taps

The NPTF standard creates a mechanical seal through thread deformation rather than sealant, demanding precise 75 percent thread engagement. Hand tapping relies on operator alignment and consistent pressure, which can vary in deep or awkward holes. High-speed steel wears faster in abrasive alloys, limiting tool life in high-volume production environments.

Questions about this item

What drill size is required for the 1/8"-27 NPTF threads on this Cleveland C64060 tap?

Use a 75 percent thread drill size Q to prepare the hole before tapping with this tool.

How do I start the semi-bottoming tap correctly in a blind hole?

Align the tap squarely, apply steady pressure, and reverse frequently to break chips; the semi-bottoming chamfer needs less initial force than a taper tap.

When should I replace the high-speed steel flutes on this 4-flute pipe tap?

Replace the tap when the cutting edges become dull, chipped, or when thread quality degrades and required torque increases noticeably.
