    Often wondered if there was something useful to be made of the twist in concrete drills. A push-pull drill seems like such an obvious use for it now. Very nice work, as usual.

    Perhaps make a yankee screwdriver (might have another name, but that is what I learned...)

    Used such a masonry bit to adjust centers on my OD grinder. Was much cheaper than buying a ball-nut and screw.
