Cleveland C27671 M10x1.50 Tap
The Cleveland C27671 is a straight-flute tap cut for M10x1.50 metric threads in a semi-bottoming style. It suits machinists and maintenance technicians who need to produce internal threads in through-holes or blind holes with a standard 6H fit.
Cobalt construction with black oxide
Cobalt substrate and a black oxide/nitride surface treatment resist wear and reduce galling during normal cutting speeds. The right-hand helix evacuates chips efficiently so heat and torque stay manageable in typical steel or alloy workpieces.
75 % thread drill size 8.50 mm
Prepare the hole with an 8.50 mm drill to achieve the specified 75 percent thread engagement before tapping. The 19.05 mm thread length and 74.61 mm overall length fit standard tap holders and allow reach in moderately deep holes without requiring specialised tooling.

Questions about this item
How do I install the M10x1.50 tap correctly and what step is commonly missed?
Drill the hole to 8.50 mm first, then run the tap straight with cutting oil; the step often skipped is using the correct 75 percent thread drill size for a 6H fit.
What maintenance or replacement will this cobalt tap need over time?
The cutting edges will dull after repeated use; resharpen the straight flutes or replace the tap when thread quality drops or torque rises noticeably.
What limit appears first during sustained threading with this semi-bottoming tap?
Chip evacuation in the 19.05 mm thread length becomes the bottleneck, requiring frequent reversal to clear swarf and prevent tap breakage.
