This model (DD350X) does not grind drill bits into the convenient split end shape that prevents them from "walking", higher models of DD do that. Price is rather steep, but the joy of being able to rescue buncha old drill bits makes it worthwhile ;).I'm giving it four stars because of one concern - also mentioned by another reviewer - my brand new motor made whining noises slowing and accelerating then slowing again by itself without any load. It seemed like the motor bearings or brushes wanted to quit. Now, after a couple of days, it appears to spin at a more stable speed but I'm keeping my three-year warranty papers handy - just in case.
