Cleveland C54838 Straight Flute Hand Tap
This Cleveland straight flute hand tap cuts 3/4"-10 UNC threads in a single pass using a taper lead. The high-speed steel body is bright finished and uncoated for general-purpose threading in steel and non-ferrous metals. Right-hand cutting action suits standard through-hole and blind-hole work.
Taper lead and H3 thread limit
The taper chamfer distributes cutting load over several threads for easier starting and reduced torque. An H3 thread limit produces a 2B class of fit when used with the specified 75 percent thread drill size of 16.50 mm. Bright finish prevents coating buildup that can alter pitch diameter in tight-tolerance holes.
Hand operation with standard tap wrench
Overall length of 4.25 in and 2 in thread length fit common tap wrenches and guide blocks. Straight flutes require manual chip clearing in deep or blind holes to avoid tap breakage. Applying cutting fluid and reversing frequently reduces the risk of chip packing and oversize threads.

Questions about this item
How often will the straight flute tap need replacement when cutting 3/4"-10 UNC threads?
The high speed steel tap wears gradually; replace it when thread gauge checks show the 2B class of fit can no longer be held on the 2 inch thread length.
What limit appears first during sustained tapping of 3/4"-10 holes?
The H3 thread limit and 75 percent thread engagement with a 16.50 mm drill size define the maximum material removal before oversize threads result.
Does the bright uncoated finish affect heat buildup during all-day tapping?
The uncoated high speed steel surface runs warmer than coated taps, so use cutting fluid and allow cooling intervals during continuous 3/4"-10 production.
