Cleveland C86210 Spiral Point Tap #10-24 UNC 3 Flute
Creates #10-24 UNC threads in through-holes using a spiral-point design that pushes chips forward
- Spiral point pushes chips forward for smoother tapping
- #10-24 UNC thread fits standard coarse-pitch holes
- Three flutes balance chip clearance and cutting strength
- HSS-E with black oxide resists wear in tough materials
- 75 % thread depth matches #25 drill for reliable engagement
Cleveland C86210 Spiral Point Tap
The Cleveland C86210 is a spiral point tap designed for through-hole threading in ferrous and non-ferrous materials. It suits maintenance technicians and machinists who need reliable chip evacuation in forward direction during production or repair work. The plug chamfer allows easier starting in existing holes or deeper thread engagement.
HSS-E Black Oxide Construction
The high-speed steel with cobalt content increases wear resistance compared with standard HSS taps. Black oxide surface treatment reduces galling and improves lubricant retention during cutting. Three flutes provide balanced chip clearance and cutting stability for consistent thread quality across repeated operations.
Thread Capability #10-24 UNC
This tap produces unified coarse threads to class 2B fit with a 75 percent thread depth using a number 25 drill size. The one-inch thread length on a two and three-quarter inch overall length handles standard through-hole depths in thinner workpieces. It is not suited for blind holes where chips cannot escape forward or for thread sizes outside the #10-24 specification.

Questions about this item
When will the 3-flute HSS-E tap need to be replaced?
Replace the tap when the cutting edges dull enough to produce oversized or rough threads in #10-24 UNC holes.
What limit appears first during sustained tapping of #10-24 threads?
The 2B class-of-fit tolerance is reached once flank wear allows the thread pitch diameter to exceed the 2B upper limit.
How much heat builds up when running this tap all day in steel?
HSS-E material and black-oxide coating reduce friction, but continuous cutting in #10-24 holes will still generate noticeable heat at the cutting zone.
