Three-Piece Tap Kit
The Cleveland C54665 is a three-piece tap kit designed for cutting internal threads in metal. It contains bottoming, plug and taper taps in a 7/16"-20 UNF size made from high-speed steel. The set suits maintenance technicians and machinists who need to create or repair fine-pitch threads in workshop or field conditions. Each tap has four straight flutes and a bright uncoated finish.
Thread Repair and Small-Batch Threading
This kit fits jobs that require a class 3B fit with a 2B thread limit and right-hand thread direction. The 7/8-inch thread length and 3 5/32-inch overall length suit through-holes and blind holes in thinner workpieces. Buyers needing larger diameters, left-hand threads or coated tools for high-volume production should look at alternative tap sets. The 75 percent thread drill size of 9.95 mm matches standard UNF tapping charts.
Sustained Hand-Tapping Performance
High-speed steel construction maintains cutting edges during repeated manual threading operations. The four-flute design clears chips effectively in both through and blind holes when used with proper lubrication. Cutting speed drops if the taps are driven by high-torque power tools without speed control. Consistent hand pressure and regular chip removal prevent binding during extended use.

Questions about this item
What size tap wrench fits the 7/16"-20 Cleveland hand tap?
Use a tap wrench sized for 7/16 inch UNF taps; the shank follows standard dimensions for that thread size.
Can I run the 7/16"-20 tap in a pneumatic tapping head with my existing 1/2 inch drive adapter?
The tap shank matches standard 7/16 inch UNF dimensions; verify your pneumatic head and adapter accept that shank size before use.
How do I confirm the 7/16"-20 threads are cut to the correct 3B class of fit?
Gauge the finished hole with a 7/16"-20 UNF 3B thread plug gauge; the GO end must enter fully and the NO-GO end must not.
