Bit to Drill Out Screw?
I have several screws that need to be removed from a 2x6 piece of wood
that forms the base of my raised stove hearth. I've tried drilling into them to be able to remove the board, but my bits won't cut into the metal and my bit is dulled. What type of bit would penetrate into the screw? I need to remove the boards so I can lay a Pergo-type floor underneath them, trim the boards, re-paint and replace the boards around the hearth.

There are commerical "screw out" kits that have a drill end and a
reverse thread end that should back the screw out Another way is a piece of copper pipe just big enough that the screw head will bit inside the pipe, use a file to cut teeth into the end of the pipe, then use that to drill out a CORE that contains the screw and a tiny bit of wood. Then plug the hole with a piece of dowel and glue, and drive new screws when you put the trim back You really are NOT going to be able to drill out the entire screw (especially if it is a steel screw) unless you have a solid carbide drill bit (mucho expensive and usually very brittle)- and trying to keep the drill bit ONLY on the screw is not usually going to work, you will wind up butchering the surrounding wood anyway Sears has a screw out kit for around $19 (maybe less - it's been a while since I checked the prices) OR, if you can get behind the trim and use a recip saw to cut off the screw, then work to get the screw out. Sometimes, if the screw head is really buggered up, you can use a Dremel tool and a cutoff wheel to cut a slot in what remains of the head and get the screw out. And sometimes putting a screwdriver in the screw and giveing a a good wack with a hammer will lossen it up so it can be removed John On 4 Jul 2005 15:07:56 -0700, "Greg" wrote: I have several screws that need to be removed from a 2x6 piece of wood that forms the base of my raised stove hearth.

I need to remove the boards so I can lay a Pergo-type floor underneath them, trim the boards, re-paint and replace the boards around the hearth. What may work for this is a 'screw extractor bit'. Said bits are like very small hole saws you chuck into your drill and they cut thorugh the wood around the screw. If possible, it is best to almost cut just past the point of the screw, not all the way through the board. That way you can back the extractor up out of the hole leaving the plug behind. Then the plug with screw inside can be broken off and removed from the board. If you drill all the way through, or th eplug breaks off and stays in the extractor it can be very difficult to remove from the extractor. Those extractors as also pretty brittle. Ordinary plug cutters may also work but if they hit the screw they will be damaged. The screw extractors are hard enough to survive _a little_ contact with the screws. -- FF |

You can use a hollow screw extractor like this:

I need to remove the boards so I can lay a Pergo-type floor underneath them, trim the boards, re-paint and replace the boards around the hearth. I'm just curious. Since these nails appear to be very hard, any chance they are concrete nails used to attach wood, etc, to concrete? If so, you may have a challenge. Lew |

Heads buggered = screw extractor per other posts. Or just use a chisel and cut out the wood around them. If you can turn the screw and it just won't back out try getting a large screwdriver under the edge of the 2x6 and prying while turning the screw. If there was no pilot hole drilled in the 2x6 - or if it was too small - the screw could be sort of wedged in it. Another way to do the same thing is to use a small screw driver jammed down into the hole against the screw threads so that it gives the screw something to climb on when you turn it. Still another way...heat the head of the screw with a large soldering iron so that it gets hot enough to char the wood a bit thereby enlarging the hole. -- dadiOH ____________________________ dadiOH's dandies v3.06... ....a help file of info about MP3s, recording from LP/cassette and tips & tricks on this and that.
