This guy has an assortment of 6 and 10 packs of HSS stubby drills on Ebay , priced good. I bought a few packs i could use. I do not know the guy , i'm passing the info on to fellow HM members . Here's one ebay item number to search for him 142105086070 kramerkramer02

Have done few tests last saturday. The old and slow shear tool was the winner. (at least for my conditions) IF the diameter was bigger, than the indexable Sandvik insert could have a better result. [Edit] Have done a research on materials too...
