Good, cheap drill bit. The big problem with drill bits, expensive or cheap, is the 200 pound gorilla on the trigger end of the drill just wants to give’r all she’s got. It wants to run the drill on the highest speed, put a lot of weight behind punching that bit through the material, and run it nonstop until the job is done. You can’t do this and expect a bit to last. A drill bit’s enemy is heat. Take your time, run the drill on the slowest gear (“1” for most drills), about half throttle, and don’t put so much force behind the drill. Let both the material and the bit cool to the touch every so often. I used this to drill a couple of holes in some body metal and it worked beautifully. Cut through LineX bedliner, and underlying sheet metal. I took my time, and the drill bit is just as sharp as it was brand new.
Now, I do not use this bit every day. I do not work with this bit. Which, I assume, if you’re needing a unibit for work, you’re not looking at a $10 one on Amazon. But if you’re like me, and just *might* need to drill large holes in sheet metal or plastic from time to time, this bit should work fine for a good while, as long as you don’t abuse it.
