Cleveland 54759 Straight Flute Hand Tap

The Cleveland 54759 is a straight-flute hand tap designed for cutting unified coarse threads in a single pass. It suits maintenance technicians, machinists and hobbyists who need to create or repair internal threads in steel, cast iron or non-ferrous metals using hand-held or light machine tapping.

Bright uncoated high-speed steel with H3 limit

The bright high-speed steel substrate provides a clean cutting surface without coatings that can mask wear. The H3 thread limit and class 2B fit deliver a standard tolerance for general-purpose fastening, while the 75 percent thread drill size of 12.20 mm guides the correct pilot hole for proper thread engagement.

9/16"-12 UNC thread with 1.66 in thread length

The tap cuts a 9/16 inch diameter thread at 12 threads per inch with a 1.66 inch thread length and 3.59 inch overall length. It handles through-holes and blind holes with adequate chip clearance in ductile materials but lacks spiral flutes for deep blind holes in high-strength alloys where chip evacuation becomes difficult.

Questions about this item

How often will the H3-class high-speed steel tap need replacing when cutting UNC threads?

The H3 thread-limit tap is made from high-speed steel and will wear gradually; replace it once the cut threads fall outside the 2B class of fit.

What stops the tap from going deeper than the 1.66 inch thread length in sustained use?

The 1.66 inch thread length on the 3.59 inch overall tool is the practical depth limit; the shank has no cutting teeth beyond that point.

Does the bright uncoated finish run hotter or need more cutting fluid during all-day tapping?

The uncoated bright finish generates more friction than coated taps, so steady coolant flow is needed to control heat during continuous operation.
