Cleveland #10-32 UNF Spiral Point Tap
The Cleveland C96111 is a cobalt spiral point tap sized for #10-32 UNF threads. It suits machinists and maintenance technicians cutting internal threads in stainless steel, high-temperature alloys or other tough materials. The right-hand plug design allows through-hole threading with efficient chip evacuation forward. Its 2B class of fit meets standard precision requirements for general-purpose fastening applications.
Cobalt substrate with black oxide finish
The cobalt construction provides higher hot hardness than high-speed steel, extending tool life when cutting abrasive or work-hardening metals. Black oxide surface treatment adds lubricity and corrosion resistance, reducing galling and improving chip flow during repeated use. Three flutes balance chip clearance with core strength, supporting consistent thread quality across production runs or repair jobs.
Designed for through-hole tapping only
Spiral point geometry pushes chips ahead of the tap, so it cannot be used for blind holes where chips must be pulled out. The 1 1/32 inch thread length and 2 3/4 inch overall length limit reach in deep or recessed features. Users needing bottoming taps, longer reach or blind-hole capability must select a different tool geometry. The #21 drill size for 75 percent thread is specified for this tap.

Questions about this item
How often will the cobalt flutes on this #10-32 tap need resharpening?
Cobalt material retains hardness at higher temperatures than high-speed steel, extending intervals between resharpening; actual frequency depends on workpiece material and cutting speed.
What limits continuous tapping with this 3-flute tool?
Chip evacuation through the spiral-point flutes becomes the limiting factor in deep or blind holes, especially when coolant flow is restricted.
How much heat builds up in the shank during all-day production runs?
Cobalt substrate conducts heat away from the cutting edges, keeping shank temperatures lower than standard steel taps under identical feed rates.
