Unhappy Broken off bit

While drilling a pilot hole for fastening the loop section of a bar latch on a door the bit broke off, probably 1/8" deep in the hole. Do I have any options other than moving the whole assembly, filling the holes and trying again?

WELCOME TO THE FORUM

Remove the broken off bit. If you had to dig out to grab it, drill a slightly oversized hole for a dowel and glue in. Then drill a new pilot a hole. If the area is a natural finish, and any repair might show other than a small circular fill...move the assembly.

Use a plug cutter

Like this: http://www.rockler.com/product.cfm?page=10614


Centered on the drill and it will remove the material around the drill, enough to be able to grasp it with a vise grips or needlenose pliers. You can then creat a plug of straight grain material, glue it in and have virtually invisible repair. bill

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

If you use this plug cutter this to take out the broken bit . The hole will be the same size as the bit. These are for cutting out plug's as you know. I don't know what size plug it would take to fill up the bigger hole. I never measured it. I only use them for plug cutting. I guess you could get some of the orignal wood and turn it round to fit the bigger hole.

Maybe come in from the back side?

Time out guys - plug cutter is going to leave a significantly larger hole needing a larger plug cutter to make the repair plug. I would dig the bit out any way I could, use a forstner to clean up the mess and then use a plug cutter the same size as the forsner to make the repair material.

Use an easy out. It works like a miniature tap and die you can get at most hardware stores

There is a product intended to solve this problem. Basically it is a stainless steel tube with teeth cut into each end. You use a drill to with the tube to cut around the broken screw. The screw usually comes out inside the stainless tube. Then you glue a dowel into the hole that was just drilled.
The HUGE advantage to this method is that the OD of the tube is 1/4". Dowels are available to match most woods also in 1/4" diameter. This device works very well for removing broken screws. There is no reason why this couldn't be used to extract broken drill bits also.

They have come down in price since I bought mine.

Use the right tool for the job.
