Cleveland C55154 Tap Identification

The Cleveland C55154 is a straight flute hand tap designed for creating unified fine threads in metal workpieces. It suits machinists and maintenance technicians who need to produce precise internal threads using hand-operated tooling.

Verify Thread Specifications Before Use

Confirm the workpiece requires a 1"-12 UNF thread with a Class 2B fit and H4 thread limit. The tap requires a 75 percent thread drill size of 23.30 mm for proper hole preparation before threading begins.

High Speed Steel Construction With TiN Coating

The tap body uses high speed steel with a titanium nitride coating to resist wear during repeated cuts. Its 5.13 in overall length and 2.5 in thread length provide reach for through holes, while the plug chamfer eases starting in pre-drilled material.

Questions about this item

Does the C55154 tap come with the 23.30 mm drill bit needed for the 75 percent thread depth?

The tap is sold alone; a 23.30 mm drill bit must be purchased separately to prepare the hole for the 75 percent thread engagement.

When would I choose the 1"-12 UNF Plug tap over a taper or bottoming version?

Choose the Plug chamfer when starting threads in a through-hole or a blind hole with enough clearance; its moderate lead cuts faster than a taper tap and reaches deeper than a bottoming tap.

What does the 2.5 inch thread length mean when I am tapping a 1"-12 hole in steel?

The 2.5 inch threaded portion limits the maximum full-thread depth you can cut in a single pass; holes deeper than that require multiple passes or a longer-reach tap.
