Cleveland M12x1.25 Spiral Point Tap
The Cleveland 86144 is a spiral point tap designed for M12 threads with a 1.25 mm pitch. It features a cobalt construction with a TiAlN coating for wear resistance. Three flutes provide chip evacuation during through-hole threading operations.
Verify hole size and material compatibility
Confirm the drilled hole matches the 75 percent thread drill size of 10.78 mm before tapping. The tool uses a right-hand thread orientation and conforms to a 6H class of fit for metric standards. Ensure the workpiece material suits cobalt tooling and the 40 mm thread length meets depth requirements.
Cobalt substrate and TiAlN coating extend service
The cobalt base material handles higher cutting temperatures than standard high-speed steel. TiAlN coating reduces friction and oxidation during cutting, which helps maintain sharp edges over repeated use. These attributes lower replacement frequency in production environments.

Questions about this item
Does the Cleveland 86144 tap include a matching 10.78 mm drill bit or must I buy it separately?
The tap is sold as a single cutting tool; the 10.78 mm drill size for 75 percent thread is a specification only, so a suitable drill bit must be purchased separately.
When should I choose the M12 x 1.25 size over other metric pitches?
Select this tap when the drawing or part calls for an M12 thread with a 1.25 mm pitch; the 6H class of fit and 3-flute cobalt design suit general-purpose through-hole threading in steel and stainless.
What does the 110 mm overall length mean for reach in a deep hole?
The 110 mm overall length and 40 mm thread length allow the tap to reach through-holes up to roughly 40 mm deep while leaving enough shank for a tap wrench or holder.
