DIY Fix: Step-by-Step Instructions to Extract a Broken Drill Bit Like a Pro

Broken drill bits are a common problem for anyone who works with tools. They can be frustrating and time-consuming to remove, but it is possible to do it yourself with the right tools and techniques. In this blog post, we will provide you with a step-by-step guide on how to extract a broken drill bit.

Tools and Materials You’ll Need

Before you begin, you will need to gather the following tools and materials:

• A pair of needle-nose pliers
• A small hammer
• A center punch
• A drill bit that is slightly smaller than the broken bit
• A screw extractor
• A tapping wrench
• A lubricant (optional)

Step-by-Step Guide to Extracting a Broken Drill Bit

1. Safety First

Always wear safety goggles when working with tools. If the drill bit is stuck in a piece of metal, be sure to clamp the metal down securely in a vise.

2. Identify the Type of Drill Bit

There are two main types of drill bits: twist drill bits and spade drill bits. Twist drill bits have a spiral flute that helps to remove chips from the hole. Spade drill bits have a flat blade that cuts through the material. The type of drill bit you are using will determine the extraction method you need to use.

3. Create a Pilot Hole (For Twist Drill Bits Only)

If you are using a twist drill bit, you will need to create a pilot hole in the center of the broken bit. This will help to guide the screw extractor. To create a pilot hole, use a center punch to make a small indentation in the center of the broken bit. Then, use a drill bit that is slightly smaller than the broken bit to drill a pilot hole.

4. Insert the Screw Extractor

Insert the screw extractor into the pilot hole (or directly into the broken bit if using a spade drill bit). The screw extractor should be slightly larger than the broken bit. Turn the screw extractor clockwise until it bites into the broken bit.

5. Apply Pressure and Turn

Once the screw extractor is biting into the broken bit, apply pressure and turn it counterclockwise. The broken bit should start to come out. If the bit is stuck, you can try applying a lubricant to help loosen it.

6. Remove the Broken Bit

Once the broken bit is loose, you can use the needle-nose pliers to remove it. Be careful not to damage the surrounding material.

7. Clean Up

Once the broken bit is removed, clean up the area and dispose of the broken bit properly.

Tips for Extracting Broken Drill Bits

• If the broken bit is small, you may be able to use a pair of tweezers to remove it.
• If the broken bit is stuck in a difficult-to-reach area, you may need to use a flexible shaft attachment for your drill.
• If you are having trouble removing the broken bit, you can try using a reverse drill bit. This type of bit is designed to remove broken bits.
• If all else fails, you can take the piece of metal to a professional tool sharpener. They will have the tools and experience to remove the broken bit safely.

Wrap-Up: Don’t Let a Broken Drill Bit Ruin Your Day

With the right tools and techniques, you can easily extract a broken drill bit. Just remember to be patient and careful, and you’ll be able to get the job done in no time.
