Cleveland C54966 Hand Tap

The Cleveland C54966 is a straight flute hand tap designed for cutting 1-1/8"-7 UNC threads. It is made from high speed steel with a bright uncoated finish and a right hand thread direction. The plug chamfer makes it suitable for through holes or blind holes with sufficient clearance. This tool is intended for general purpose threading in ferrous and non-ferrous materials.

Verify drill size and thread fit

Before use confirm that the tapped hole is drilled to the 75 percent thread drill size of .9858 in. The thread limit is H4 with a Class of Fit 2B. Ensure the workpiece material is compatible with high speed steel cutting tools. Proper alignment and lubrication are required to produce accurate threads and prevent tap breakage.

Cutting performance and tool life

In normal use the high speed steel construction provides good wear resistance for hand tapping operations. The straight flute design allows chips to collect in the flutes so frequent reversal is needed to clear them. Cutting fluid reduces friction and heat at the cutting edges. The bright finish offers no additional lubricity so adequate coolant is essential for tool life.

Questions about this item

Does the C54966 tap come with a handle or wrench, or must I supply my own?

The tap itself is the only item included; a T-handle, tap wrench or other drive tool must be purchased separately.

Is the C54966 available in other thread sizes or pitch options?

This part number is fixed at 1-1/8"-7 UNC; different diameters or pitches carry different Cleveland part numbers.

What does the 2.56 in thread length mean when I am tapping a through-hole?

It gives 2.56 in of cutting threads; the hole must be at least that deep plus clearance for chips and the 0.9858 in drill size.
