Spiral flute tap question

(1/2) > >>

MadNick:
Morning,

I managed to pick up a brand new 5/16 UNC spiral flute tap for pennies. It doesnt feel like its made of steel though, looks more like a ceramic finish to it.

My question is, would this be ok to use as a plug tap in stainless steel please?

DMIOM:
The surface can be misleading with all sorts of coatings - however is there a coloured band on it?  if so, what make is it?

Yellow is usually general purpose and Red for high tensile; BUT then depending on maker, typical coding is Green = stainless and Blue = aluminium (however Guhring have Blue for stainless !)

MadNick:
My mistake - it is HSS, worked like a treat :)
