Cleveland C54661 Straight Flute Hand Tap
This Cleveland C54661 straight flute hand tap cuts internal UNF threads in a 7/16"-20 size. It is designed for general-purpose threading tasks in maintenance, repair and light production environments where a taper lead eases starting.
Taper lead and high-speed steel construction
The taper chamfer distributes cutting force across several threads to reduce load on each flute during sustained hand operation. High-speed steel retains hardness at the temperatures generated by continuous cutting, while the bright uncoated finish suits ferrous and non-ferrous materials without coating buildup.
UNF 7/16"-20 Class 2B fit with H3 limit
The H3 thread limit and Class 2B tolerance define the allowance and tolerance zone for the finished thread. A 75 percent thread depth requires a 9.95 mm drill size to produce the correct minor diameter. The 7/8 inch thread length and 3 5/32 inch overall length set the maximum reach for through holes.

How much power does the Cleveland C54661 tap draw during continuous use?
The Cleveland C54661 is a manual hand tap with no motor, so it draws zero electrical power and generates no heat or noise when cutting threads.
What tool holder do I already need to turn the Cleveland C54661 tap?
You need a tap wrench or T-handle that fits the square on the 7/16"-20 UNF tap shank to apply torque by hand.
Will the Cleveland C54661 tap cut threads in an existing 9.95 mm drilled hole?
Yes, the 9.95 mm drill size matches the 75 percent thread depth specification for this 7/16"-20 UNF H3 tap.
