Hartland Two Flute Drills always offer many different web styles
to suit the material being machined. The main advantage of Hartland
Two Flute Drills over standard drills is the way we grind the
taper on the tool. If a drill is to go through a bushing we only
put on a minimum amount of taper. If a drill is to do heavy drilling
we will put .0004/.0002 backtaper per inch. This kind of special
grinding assures a quality hole.
