I have two different style of these bits, both greenlee's, both have the screw tip and I can't seem to get a bite on the wood I'm trying to drill through. Is it just me or do others have problems getting through with these? Maybe the style without the screw tip works better? Any suggestions for other products to get a hole through the floor to the basement when adding a new receptacle? This project is my pet peeve cause it just doesn't ever seem to go smooth. Many thanks, Ed.
I use diversibits all the time, they make me look like a magician and my customers very happy. I mainly use a 9/16", 6 ft long bit with a screw tip. The only time I ever have a problem is when the bit part (not the screw) gets dull, then the bit will just stop after the screw exits the wood. I did try one small diameter bit that I couldn't get to work right once. If you don't have one, you might want to invest in a diversibit placement tool, it helps you get the bit going in the right direction so you don't drill through a floor or wall that you don't want to.

Ahh, The 6' drill bit, I remember it well.In my younger years when my hair was somewhat longer:> ) I was on a ladder with my head above the suspended ceiling trying to drill down thru a "cat" in the wall. I was holding the drill in my right hand and the bit in my left hand guiding it down the wall.The bit was behind my head and you guessed it. At full speed it grabbed a chunk and removed it. (ouch) About a 4 inch circle of hair was missin. Thankfully no skin came with. Haven't used one since:> )
I've sharpened mine a few times using a regular bench grinder. As they come from the factory, they seem to have a fairly dull cutting edge on them. With a grinder, you can make the edge quite a bit sharper, which makes them work a heck of a lot better.
These things work pretty well until they hit a nail or other metal object. It is a good thing that they resharpen easily, because it is easy to wipe them out if you hit metal with them.
