Gave one star because it could turn my work piece into scrap. Chips stick to it. I've bought hundreds of drill bits over the past 25 years and so far none of them have been magnetic. I didn't even know it was a thing. Now I have to try if I can save my workpiece. I worked on it for eight hours and everything was done except for this hole. A magnetic chip is now in the 1/4" wide, 6" deep hole. I guess I'll have to find a place to degauss it. Do yourself a favor - if you buy this drill, see if the shavings stick. on it before you open the package. If they stick, keep the packaging sealed and send it back. Not worth the headache.
