Straight Flute Hand Tap Kit #3-56
This three-piece kit contains taper, plug and bottoming taps for cutting UNF #3-56 threads. The taps are made from high-speed steel with a bright uncoated finish and feature three flutes. Each tap has a thread length of 1/2 inch and an overall length of 1 13/16 inches. The set is designed for right-hand threading to a class 2B fit with an H2 thread limit.
Suited for manual threading in maintenance
Mechanics and hobbyists who need to create or repair fine UNF #3-56 threads by hand will find this kit appropriate. The three taps allow progressive cutting from start to bottom in through or blind holes. Buyers who require machine tapping, coated tools for longer life, or larger thread sizes should look at alternative tooling.
Check your drill size and material compatibility
Before ordering, confirm you have a #46 drill bit for the recommended 75 percent thread engagement. Verify the workpiece material is suitable for uncoated high-speed steel taps. Ensure the 1 13/16 inch overall length and 1/2 inch thread length fit your workpiece thickness and fixture clearance.

Questions about this item
What size drill bit do I need before tapping with the #3-56 tap?
Use a #46 drill bit to achieve the 75 percent thread depth recommended for this tap.
Can I use the taper tap to start threads in a blind hole?
The taper tap is best for through-holes; start with the plug tap for blind holes and finish with the bottoming tap.
How do I verify the threads are cut to the correct 2B class of fit?
Check the finished threads with a #3-56 UNF 2B thread gauge; they should accept the go gauge and reject the no-go gauge.
