Cleveland M10x1.25 Spiral Point Tap
The Cleveland C86142 is a right-hand spiral point tap for cutting M10x1.25 metric threads in through holes. Its cobalt substrate with TiAlN coating suits production threading in steel and stainless alloys where tool life matters. The 100 mm overall length and 40 mm thread length reach deep features without extension tooling. Three flutes evacuate chips ahead of the cut to reduce torque.
Thermals noise and power draw
Hand tapping generates negligible heat and noise; machine tapping runs cool with flood or mist coolant because the spiral point pushes chips forward. Cobalt retains hardness at elevated cutting temperatures so the tool does not soften during sustained cuts. Power draw depends entirely on the machine spindle and feed rate, not on the tap itself.
Replaces worn HSS taps in high-volume M10 jobs
The jump is worth it when standard high-speed steel taps dull quickly in stainless or alloy steel, forcing frequent tool changes. The TiAlN coating and cobalt base extend intervals between resharpening. It is not for blind holes, left-hand threads, or thread sizes other than M10x1.25.

Questions about this item
How do I install the Cleveland C86142 M10x1.25 tap and what step is often missed?
Drill the hole to the 0.3438 in size for 75 percent thread, then run the 100 mm cobalt tap with cutting fluid; the step often missed is using the correct drill diameter before tapping.
What maintenance or replacement will the Cleveland C86142 tap need over time?
The TiAlN coating on the cobalt flutes resists wear, but the cutting edges will dull after repeated M10x1.25 threads; replace the tap when thread quality drops or torque rises sharply.
What limit appears first when using the Cleveland C86142 tap continuously?
Heat buildup in the 40 mm thread length is the first limit during sustained tapping; the cobalt substrate handles temperature well, but excessive speed without coolant will degrade the TiAlN coating fastest.
