Cleveland C54930 Straight Flute Hand Tap
The Cleveland C54930 is a straight flute hand tap designed for cutting internal threads in a 1 inch-12 UNF size. It is made from high speed steel with a bright uncoated finish and features a right-hand thread direction. This tool suits machinists and maintenance personnel who need to create precise threads in metal workpieces.
Replaces worn or damaged taps of the same
When an existing tap no longer produces clean threads to a 2B class of fit, this H4 limit tool restores accuracy. The jump is worth it if the current tap shows chipping, excessive wear, or cannot achieve the required 75 percent thread depth with a 23.30 mm drill size. Its 2.5 inch thread length and 5.13 inch overall length match the original dimensions.
Suits users cutting UNF threads by hand or machine
This tap fits applications needing a bottoming chamfer in high speed steel. It is not for buyers who require a coated tap for longer life in abrasive materials, nor for those needing a different thread form, pitch, or size. Users without the correct 23.30 mm drill size or a suitable tap holder should look at other options.

Questions about this item
What size drill bit do I need for the 75 percent thread on this 1"-12 UNF tap?
Use a 23.30 mm drill bit to achieve the 75 percent thread depth before tapping.
How do I start the tap straight in the hole without it binding?
Apply steady pressure while turning the square shank slowly; the straight flutes clear chips best when the tap enters perfectly perpendicular.
When should I replace this high-speed steel tap?
Replace it once the cutting edges dull enough to produce rough threads or require excessive force on 1"-12 UNF holes.
