Cleveland C86211 Spiral Point Tap
The Cleveland C86211 is a spiral-point tap designed for cutting #10-32 UNF threads in through-hole applications. It suits machinists and maintenance technicians who need reliable thread production in steel or similar materials.
Chip evacuation under sustained load
The spiral-point geometry pushes chips ahead of the tap, reducing flute clogging during continuous threading operations. This design maintains consistent cutting action and helps prevent tap breakage when multiple holes are processed in sequence.
#10-32 UNF thread specification
The tap cuts a #10-32 UNF thread with a 2B class of fit, requiring a #21 drill size for 75 percent thread engagement. It is not suitable for metric threads, coarse UNC pitches, or blind-hole tapping where chip clearance differs.
Highlights
- #10-32 UNF thread fits precision fasteners
- Spiral point pushes chips ahead for through-holes
- Three flutes balance strength and chip clearance
- Steam oxide coating resists wear and galling
- Cobalt substrate handles high-temp cutting

Questions about this item
Does the 10-32 UNF tap generate excessive heat during extended threading operations?
The spiral-point design pushes chips forward, reducing friction and heat buildup during continuous use.
What drill size must I already own to prepare the hole for this #10-32 tap?
A #21 drill bit is required to create the 75 percent thread depth hole before tapping.
Will this 3-flute cobalt tap cut cleanly in the older mild steel stock I keep in the shop?
Cobalt construction with steam oxide finish handles mild steel effectively while resisting wear.
