And where can I src from here in the US, a decent quality, 10mm 1.5 pitch, solid carbide spiral machine tap? Ebay's search engine and the sellers have no clue that there is a difference between HSS and carbide, using both words to describe the same item, nor what the difference is between a spiral tap and a spiral point. And neither do the sellers. :( Thanks guys. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
