Cleveland 1/2"-13 UNC Plug Tap

The Cleveland C54727 is a straight-flute hand tap designed to cut internal threads in a 1/2 inch diameter workpiece with a 13 threads-per-inch UNC pitch. Made from high-speed steel with a bright uncoated finish, it suits general-purpose threading tasks in maintenance and repair workshops. The plug chamfer allows starting in through-holes or blind holes with adequate clearance.

Mechanics cutting standard UNC threads

This tap suits mechanics and fabricators who need to create or repair 1/2"-13 UNC Class 2B internal threads using a 27/64 inch drill size for 75 percent thread engagement. It is not for buyers who need a bottoming chamfer for threading to the bottom of a blind hole, nor for those requiring a coated or spiral-flute tap for difficult materials or high-volume production runs.

3.38 inch overall length

The overall length measures 3.38 inches while the threaded portion extends 1.66 inches, fitting standard tap wrenches and guiding the cut to the correct depth. The H3 thread limit ensures the finished thread meets the 2B class of fit. Verify that your drill size and hole depth match these dimensions before threading.

Questions about this item

Does the Cleveland C54727 tap come with a 27/64 inch drill bit or must I buy it separately?

The tap requires a 27/64 inch drill for 75 percent thread depth; that drill bit is not included and must be purchased separately.

Should I choose the H3 thread limit for a standard 2B class of fit?

Yes, the H3 limit is designed for a 2B class of fit in 1/2"-13 UNC threads, matching common general-purpose requirements.

What does the 1.66 inch thread length mean when I use this tap in a through-hole?

The 1.66 inch thread length is the cutting portion; in a through-hole it will cut threads up to that depth from the entry face.
