Reviews

Mibro 3/4 in. Silver and Deming Drill Bit, 270811 is rated 2.7 out of 5 by 3.
Rated 5 out of 5 by from Great if used PROPERLY! Reviews on these bits are from people using them with hand held drills. These bits are not made for that!! These are LOW and I stress LOW speed bits designed for DRILL PRESSES!!! If you want a drill bit for your hand held you cant beat a COBALT, and even they cut better on the low speed settings on the drill!! Cut too fast on harder materials and you burn the bits rendering them USELESS.

Rated 2 out of 5 by from Not good for full-timers who own tools with power The shank is too small for the size of the bit and the steel is too soft. If (when) the bit grabs when finishing the hole with a 1/2" hand-held corded drill, the shank bends easily. Why put a 3/8" shank on a 3/4" bit? Larger bits require larger shanks. I suppose it is fine and dandy for those with a weaker 3/8" drill who do not often drill heavy steel, but for people who rely on their tools for their living daily...NO!
