Cleveland 1/8"-27 NPT Pipe Tap

The Cleveland C56701 is a high-speed steel pipe tap designed for cutting 1/8"-27 NPT threads. Its TiN coating and four-flute geometry suit maintenance technicians and pipe fitters who need reliable thread creation in metal piping systems.

Semi-Bottoming Thread Limit

The semi-bottoming chamfer allows threading close to the bottom of blind holes, yet the NPT taper standard determines the practical engagement depth. Users must match the 75 percent thread drill size Q to achieve correct thread form without excessive torque or tap breakage.

3/4 Inch Thread Length Capacity

The 3/4 inch thread length on a 2 1/8 inch overall body handles standard pipe couplings and fittings. It runs out on deeper blind holes or thick-walled components requiring full thread engagement beyond the cutting length.

Questions about this item

Should I choose the 1/8"-27 NPT tap or a different thread size?

The 1/8"-27 NPT tap matches 1/8 inch pipe threads with 27 threads per inch; pick a different size only if your fitting calls for another diameter or pitch.

What does the 75 percent thread drill size Q mean when I am cutting threads in the workshop?

Drill the hole with a size Q bit to remove 75 percent of the thread material, giving the tap a clean start and reducing breakage in steel or iron.

How does the NPT standard affect the way this tap seals in practice?

NPT threads are tapered, so the 1/8"-27 tap cuts a sealing thread that tightens as it engages, requiring sealant or tape for leak-free joints.
