Cleveland C58547 Spiral Flute Tap #10-32 UNF
The Cleveland C58547 is a spiral flute tap designed for cutting #10-32 UNF threads in through-hole and blind-hole applications. It suits machinists and maintenance technicians who need reliable thread production in a range of ferrous and non-ferrous materials. The H3 thread limit targets a 2B class of fit for standard assembly requirements.
High-Speed Steel Bright Finish Three-Flute Design
Constructed from high-speed steel with a bright uncoated finish, the tap resists wear during general-purpose threading tasks. Three flutes provide balanced chip evacuation and cutting stability, while the spiral flute geometry pulls chips away from the cutting zone in blind holes. The bottoming chamfer allows threading close to the bottom of drilled holes.
Replaces Worn Or Damaged #10-32 Taps
This tap replaces worn or damaged #10-32 UNF tooling when thread quality declines or tool failure occurs. The upgrade is worth it when existing taps produce oversize threads, exhibit chipping, or struggle with chip evacuation in deeper holes. Buyers needing a different thread limit, coating, or flute count for specialised materials should select an alternative specification.

Questions about this item
What thread standard and pitch does the #10-32 UNF tap cut?
It cuts a Unified National Fine thread with a 32 threads-per-inch pitch, suitable for Class 2B fit.
What drill size is required to produce the 75 percent thread depth for this tap?
A number 21 drill is specified for the 75 percent thread engagement before tapping.
How do you start the tap correctly in the hole?
Use a tap wrench on the square shank, apply steady downward pressure while turning clockwise to engage the right-hand threads, and back off each half-turn to clear chips.
