Thread Size and Standard

This Cleveland C55685 pipe tap cuts 1/2"-14 NPTF threads for pneumatic and hydraulic connections. It is designed for mechanics and maintenance technicians who need reliable tapered pipe threads in workshop or field service applications.

Material and Coating Performance

The high-speed steel body with TiN coating resists wear during threading operations in steel and iron pipe. Right-hand cutting geometry with four flutes provides stable chip evacuation and consistent thread quality under normal hand or machine tapping conditions.

Drill Size Requirement

A 75 percent thread engagement requires a 0.7031 in drill size before tapping. This specific pilot diameter is the critical specification that determines whether the tap will produce compliant NPTF threads for the intended fitting.

Questions about this item

How do I install the Cleveland C55685 pipe tap and what step is often missed?

Drill the hole with a .7031 inch bit for 75 percent thread engagement, then run the tap straight with steady pressure; the step most often missed is using the correct drill size before tapping.

What maintenance or replacement will the Cleveland C55685 tap need later?

The TiN coated high speed steel flutes resist wear, but the cutting edges will dull after repeated use and the tap must be replaced when threads become undersized or torn.

What limit appears first when using the Cleveland C55685 tap continuously?

Heat buildup in the 4 flute design reduces cutting efficiency first, so allow cooling between holes to maintain thread quality in NPTF applications.
