Review on Irwin 4In XL Speedbor Bit by Edwin Cen

This is a quality drill that works and will hold up well. I was surprised that it doesn't have a quick release buckle, which is hard to tell from the photos. It is tapered but has no grooves for use in quick couplers on power drills. For a mid-range drill this would be fine, but I expected more considering how much more it costs than other bits. better than the cheaper options.
