How To Remove Broken Drill Bit From Wall?
Getting halfway through drilling a hole and having the drill bit break off is one of the most annoying things that can happen. There appears to be no way out of this impenetrable hole. It’s fortunate that specialised equipment is available to remove shattered pieces. There is a good chance that you already own one of these tools.
We recommend using simple locking pliers to fix damaged parts. Screw extractors are an option if that doesn’t work. With a tapered drill bit with a reverse thread, even the most resistant broken parts may be removed by utilising these conical, reverse-threaded bits.
Slow down and take your time. For the greatest results, drill directly into the bit. The extractor should still operate even if the hole is slightly slanted.
Locking Plier Method
Use a pair of locking pliers to secure the drill bit’s fractured end if feasible. Remove the bit by twisting the pliers counterclockwise to back it out and discard it.
Chisel out a tiny recess around the bit to get to the fractured end if you can’t reach it with pliers. It’s important to make the cutout large enough so that the pliers tip can be locked onto the tip of the bit.
Remove the bit by twisting the pliers counterclockwise.
Punch the broken bit in the middle using the end of a centre punch that is centred on the broken bit. Hammer the end of the centre punch with a hammer so that a tiny indentation is formed.
Use a drill/driver to attach a drill bit to the drill. The drill bit should be smaller in diameter than the broken one. If the drill bit is 3/8-inch, for example, use a 1/4-inch drill bit or a smaller drill bit to drill the hole. Put the bit’s tip directly on the divot for best results. At least half an inch should be drilled into the end of the drill bit.
Use an extractor bit with a cone-shaped end to insert into the hole. The end of the extractor should be somewhat smaller in diameter than the hole in which it is inserted. To keep the extractor in place, use a hammer to tap the end of it.
Wrench the top of the extractor using a wrench. This is why the top of the extractor has flat edges. To remove the damaged piece, use a wrench to turn the extractor counter-clockwise.

Wear goggles while using power tools to avoid damaging your eyes. Tools might be heated or have sharp edges. Extractors may not be able to remove pieces smaller than 1/4-inch. In this scenario, the only alternative may be to entirely remove them using a drill bit of the same size. Consider using a drill bit that is really hard.
How to prevent breaking a bit while drilling?
- Thin drill bits are more prone to breaking than thick ones. Drill slowly and carefully with a smaller drill bit in order to avoid damage.
- Cutting oil should be used before drilling. Furthermore, it prevents the drill bit from breaking even while drilling into strong materials. In addition, the drill will not overheat. Oil is not required for diamond drill bits.
- Slide the drill bit as high as possible when inserting it. As a result, the drill will be in a solid, stable position.
- The drill bit might be damaged if you use too much force. The chuck should also be tightened before beginning drilling.
- To avoid the drill bit cracking, change it often. According to the data, a power drill is responsible for around 5800 injuries per year.
