Cleveland C54972 Hand Tap

The Cleveland C54972 is a straight-flute hand tap designed to cut 1-1/8"-12 UNF internal threads in through-hole or blind-hole applications. It is intended for machinists and maintenance technicians who need a reliable threading tool for general-purpose metalworking tasks.

Sustained cutting behaviour

The high-speed steel construction maintains edge hardness during repeated hand-tapping cycles, while the uncoated bright finish reduces galling when cutting ferrous or non-ferrous alloys. The H4 thread limit and 2B class of fit ensure consistent pitch diameter control across multiple holes without the tap binding or oversizing the thread form.

Thermal and power characteristics

Hand operation generates minimal heat compared with machine tapping, so coolant or cutting oil applied at the 2.56-inch thread length is sufficient to manage temperature rise. The 5.44-inch overall length provides adequate leverage for manual torque application, keeping required operator effort low and eliminating the need for powered drive equipment.

Questions about this item

Does the H4 thread limit on the 1-1/8"-12 UNF tap create extra cutting resistance that heats up the tool during long runs?

The H4 limit and 75 percent thread drill size of 1.0438 in are designed for standard class 2B fit, keeping cutting forces normal for hand tapping so heat build-up stays low.

What size drill bit must I already own to prepare the hole for this 1-1/8"-12 UNF tap?

You need a drill bit of 1.0438 in to match the 75 percent thread drill size specified for the tap.

Will the 5.44 in overall length and 2.56 in thread length let me reach threads on older equipment with deep bosses?

The 5.44 in overall length and 2.56 in thread length provide the reach needed for many deep-boss applications on legacy machines.
