Cleveland C54056 Straight Flute Hand Tap
The Cleveland C54056 is a new straight flute hand tap designed for cutting internal threads by hand or with a tap wrench. It produces a #1-64 UNC thread in a right-hand direction using two flutes. The plug chamfer makes it suitable for through holes or blind holes with adequate clearance. It is made from high speed steel with a bright uncoated finish.
Compatibility checks before ordering
Verify that the workpiece material suits an uncoated high speed steel tap and that the required class of fit is 2B. The thread limit is H1 and the thread length is 3/8 in. Use the specified 75 percent thread drill size of 1.45 mm to prepare the hole. Ensure the overall length of 1 11/16 in fits your workspace and holding fixture.
Who this suits and who should look elsewhere
This tap suits machinists and maintenance technicians cutting #1-64 UNC threads in general purpose materials where a bright finish is acceptable. Buyers needing a coated tap for longer life in abrasive or tough alloys should look elsewhere. Those requiring a bottoming or taper chamfer style need a different tap geometry. Users who need a larger thread size or different thread standard must select another tool.

Questions about this item
Does the Cleveland C54056 tap come with a handle or drill bit?
The box contains only the straight-flute hand tap. A tap wrench and the 1.45 mm drill bit for the 75 percent thread hole must be purchased separately.
When should I choose the #1-64 UNC plug tap with H1 limit?
Choose this version when cutting new internal threads in a through-hole or a blind hole with enough clearance, and when a class 2B fit with H1 tolerance is specified.
What does the 1 11/16 in overall length mean when I am tapping by hand?
The 1 11/16 in overall length gives a comfortable grip area while the 3/8 in thread length limits the depth of cut in a single pass.
