Heat-Resistant Cobalt Steel Short-Length Drill Bits

100% agree, we originally bought a couple screw machine lengths drills for our CNC machine so we wouldn't have to center drill low accuracy parts. We ended up using them for everything. They are much easier to line up than a long jobbers length drills when using handheld drills and we very rarely need anything longer.
