Usage:Step Drills allow drilling multiple sized holes in one step for reduced processing steps and each use produces a clean chamfered hole in the material. Can be used on plate, bar, tube, or box section. Cutting fluid or drill lubricant is recommended (the type of fluid depends on the material being machined). As with all machining, it is best to go slow, keep the tool cool, and use LOTS of lubricant. They are industry fabrication quality and IMHO – one of the best hand tools around.
