Cleveland C56020 Hand Tap 1/2-13
The Cleveland C56020 is a straight-flute hand tap cut for a 1/2"-13 UNC thread. Made from high-speed steel with a black oxide finish, it is intended for general-purpose threading in ferrous and non-ferrous materials. The plug chamfer suits through holes and blind holes with adequate clearance. Right-hand cutting direction matches standard fasteners.
Replaces worn or undersized taps
Swap in this H3-limit tap when an existing tool no longer produces a 2B class of fit or when thread gauges show excessive wear. The 75 percent thread drill size of 27/64 in provides a reliable starting point for new holes. The jump is worth it when thread quality checks fail or when a fresh tap restores consistent engagement on 1/2"-13 hardware.
Suits maintenance and low-volume threading
Mechanics and fabricators cutting occasional 1/2"-13 threads by hand or with a reversible drill will find the straight-flute geometry easy to control. High-volume production lines or tough alloys that demand spiral-point or spiral-flute evacuation should look at a different tap style. Buyers needing metric pitches or finer UNF series must select another tool.

Questions about this item
What drill size matches the 27/64 in tap drill spec for this 1/2-13 tap?
Use a 27/64 in drill bit to produce the 75 percent thread depth this tap requires.
How do you start the plug tap straight in a blind hole?
Apply steady axial pressure while turning the tap clockwise; the plug chamfer guides the first threads but misalignment will cross-thread the hole.
When does the H3 thread limit on this high-speed steel tap require replacement?
Replace the tap when thread gauging shows the 2B fit is exceeded or when cutting edges show visible wear that affects thread quality.
