Mibro 5/16 in. Diameter Cobalt Steel Drill Bit is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Excellent product! I am currently building a project for the ranch and am using a great deal of metal. As a result, I am using The MIBRO TOUGH METALS COBALT drill bits. They are the best bit for the money I've found and I particuarly like the the "flats" in the shaft to keep the bit from spinning in the chuck as well as the cutting properties.
