Cleveland C54359 Straight Flute Hand Tap #10-32

Cleveland #10-32 Straight Flute Hand Tap

This Cleveland C54359 is a three-piece tap kit designed for cutting internal threads in a #10-32 UNF size. It is made from high-speed steel with a bright uncoated finish and features a right-hand thread direction. The kit suits machinists and maintenance technicians who need to create Class 2B fit threads by hand. The H3 thread limit provides standard tolerance for general-purpose threading work.

Four-flute design for through-hole tapping

The straight flute geometry with four flutes works best for through-hole applications where chips can fall ahead of the tool. A #21 drill size produces the recommended 75 percent thread engagement before tapping begins. The 7/8 inch thread length and 2 3/8 inch overall length fit standard tap handles and wrenches. No external power or specialised holders are required to operate these hand taps.

High-speed steel holds up under repeated use

High-speed steel construction resists wear when cutting ferrous and non-ferrous materials during extended hand-tapping sessions. The uncoated bright finish allows visual inspection of cutting edges between operations. Consistent pressure and proper lubrication maintain thread accuracy across multiple holes without premature dulling. The tool is not suited for blind holes where chip evacuation becomes difficult.
