Cleveland #6-32 UNC Hand Tap Set

This three-piece kit contains taper, plug and bottoming taps for cutting #6-32 UNC threads. The straight-flute design is made from high-speed steel with a bright uncoated finish. Each tap measures 2 inches overall with an 11/16 inch thread length. The set conforms to class 3B fit and H2 thread limit for right-hand threads.

Suited for through and blind holes.

Hand-operated tapping in steel or non-ferrous metal is the intended use. The straight flutes suit both through holes and blind holes when turned by hand. The set does not suit high-speed machine tapping, spiral-point chip ejection or left-hand thread cutting. Buyers needing coated tools for stainless steel or production speeds should consider other options.

H2 thread limit and 75 % drill size #36

The H2 limit controls the pitch diameter tolerance for a class 3B fit. A #36 drill at 75 percent thread engagement produces the correct minor diameter before tapping. Matching this drill size and limit ensures the finished thread gauges correctly.
