How to Remove a Broken Carbide Drill Bit

Check the Broken Bit

Start by looking closely at the broken piece. See how much of it is sticking out from the work surface. Understanding this will help you decide the best way to get it out.

Lubricate the Area

Put some lubricating oil around the broken bit. This helps loosen it up and makes it easier to remove. Give the oil a bit of time to work its way in.

Use Needle-Nose Pliers

If you can see a part of the bit above the surface, grab it with needle-nose pliers. Hold it tight and gently twist it. The aim is to ease it out slowly, avoiding any extra damage.

Try the Punch and Drill Method

If the bit is flat against the surface, you’ll need to do a bit more work. Use a center punch to make a small dimple on the top of the broken bit. This gives you a starting point for drilling.

Next, take a left-handed drill bit or a screw extractor and set your drill. These tools have a reverse thread that helps pull the broken bit out as you drill.

Drill Carefully

When you start drilling, keep the pressure light and steady. Pushing too hard might make things worse. Let the tool do its job, and have patience. It might take a little time, especially if the bit is really stuck.

By following these steps, you can remove a broken carbide drill bit without too much trouble. Remember, the right tools and a bit of patience are your best friends in fixing this issue.
