How to Drill a Hole Bigger Than Your Drill Bit

When it comes to drilling holes, a lot goes into it. It would be best if you had the right tools, techniques, and mindset. If you’re trying to drill a hole more significant than your drill bit, then you’re in for a challenge. But with the right tips and tricks, you can do it without any trouble. So if you’re ready to take on this challenge, keep reading for some helpful advice on how to drill a hole bigger than your drill bit.

How to Drill a Hole Bigger Than Your Drill Bit

If you need to drill a bigger hole than your drill bit, you can do a few things. You can use a hammer and chisel to break away the material around the edge of the hole, or you can use a more significant drill bit to create a pilot hole. Keep in mind that if the hole is too big, it might not be strong enough to hold screws or other fasteners. Be sure to use caution when drilling large holes.

10 Best Ways on How to Drill a Hole Bigger Than Your Drill Bit:

1. Wiggle the Drill:

Wiggle the drill bit as you push it through the surface. This will enlarge the initial hole and make a smoother tunnel for your new bolt to go through. Be careful not to wiggle too much, though, or you might break the bit off in the material!

2. Pull Back and Cut:

If possible, drill a pilot hole first. Drill a small hole into the surface, then pull the drill back and forth through it to enlarge it. Finally, please insert your new bolt and tighten it as normal. This is a good method for drilling holes in wood where you don’t want to accidentally split the material apart with too much force from wiggling or uneven pressure.

3. Use a Bigger Bit:

Sometimes bigger is better, so use the biggest bit you have access to! Just be careful not to break it while trying to get it through the surface because that could cause some pretty severe damage to whatever you are drilling into.

4. Drilling Multiple Holes and Filing:

If possible, drill multiple holes and then file out the excess material between them. This will result in a much bigger hole than other methods, but it is time-consuming and difficult to perfect without any sharp edges around the bolt hole.

5. Use a Drill Guide or Hole Saw:

A drill guide allows you to control the depth and size of your drill, so it can be a great tool for drilling bigger holes. When using a drill with a hole saw, widen the pilot hole into one that is at least as wide as your most significant bit. Then run the saw through the material slowly and with even pressure to enlarge the hole.

6. Blow It Out with Compressed Air:

Using compressed air, blow out the shavings from both sides of the wall you are drilling into. This will enlarge the initial opening and lead to a smoother tunnel for your new bolt to go through. Be careful not to push any foreign objects into it, though, because you don’t want them to get stuck inside the wall, causing further damage!

7. Use a Chisel:

While this may seem like an odd way to enlarge your bolt hole, it works well. Use the chisel’s back as a brace and tap on it gently with a hammer to create small flakes and chips of material. Then just run the bolt as usual through the new, larger opening.

8. Use a Wooden Dowel and Sandpaper:

Use your drill to create a small hole in the material. Then cut a wooden dowel, sandpaper, and epoxy into an L-shape that can fit snugly into the hole. After allowing the adhesive to dry, pull it out of the wall to enlarge it with your new bolt!

9. Drill a Pilot Hole and Cut from Behind:

Drill a pilot hole into the material, then tape a piece of cardboard over the backside to catch any falling debris. After drilling through the front, push it out from behind with your hands or a hammer. While this method is fairly simple, it does create jagged edges that you will have to smooth out with some sandpaper.

10. Use a Rotary Tool:

Using a rotary tool is excellent for drilling through wood or soft plastic that can’t be drilled with most power tools. Instead, use the most significant bit you have access to and saw away at the material slowly, moving back-and-forth with even pressure to cut larger chunks of material out. This method is simple enough, but it isn’t easy to make the hole perfectly smooth without sanding, which takes time.

Some Tips and Suggestions

Here are some tips and suggestions on how to drill a hole bigger than your drill bit.

1. Remember to use a clamp.

2. Don’t use pressurized water unless it is necessary for you to do so. The more complicated the project, the more likely it is that this trick will not work.

3. Don’t use a grinder unless you know what you’re doing.

4. Don’t breathe the dust created while using power tools.

5. Remember that this trick can only work if your drill bit is smaller than the desired hole size (such as when enlarging holes for picture hanging brackets) and that it can also be used to create a series of holes that gradually get bigger.

6. Remember to use a drill with a sharp bit for this trick to work well.

7. If you don’t feel comfortable doing this yourself, always have someone more experienced help you out!

How to Choose Drill Bits by Size?

When choosing a drill bit, there are several aspects to keep in mind the material that will be drilled (brass, aluminum, etc.), and the size of the hole desired. When purchasing new bits or selecting from your existing set, it is essential to understand the sizing of each. Most drill bits come on graduated sizes; for example, each bit in a set may have an identifying number.

These represent the size of the drill bit (the larger the number, the smaller the bit). You can then use this to determine which is needed for your project. For example, let’s say you wanted to cut a hole 1/2″ in diameter.

You should select a drill bit 1/8″ larger than your desired hole size, for example, a 3/8”. This would provide an opening of the desired size with room to spare.

You can get away with using bits that are slightly larger than what you need, but if the hole is too small, it will not fit properly. It should also be noted that this formula does not work for every material. Some metals (aluminum, for example) cut quickly with smaller bits, while steel usually requires something much more significant to begin cutting.

Is There a Way to Drill Without a Drill?

Yes. You can drill without a drill if you have an anchor, some screws, and patience. Drill the appropriate-sized hole for your screw into your furniture or wall with the electric drill.

If it does not fit snugly in the hole, use sandpaper to make it smaller. Anchor the screw/anchor with glue, then screw it into the anchor. You can also use something other than screws, but make sure whatever you are using would not function as a screwdriver if hanging onto the head of an electric drill.

Use Sander Tool

How Can I Drill a Bigger Hole Than the Bit Allows?

You can drill a bigger hole than your drill bit allows by using an abrasive material such as sandpaper to wear down the screw, anchor, or wall until it is the same size as the bit. This will make it easier to drill, but it is essential to be careful not to wear the material away any faster than you are wearing down the screw, anchor, or wall because if you do, you would have made a more giant hole than desired.

What if the Drill Bit is Too Large for the Hole?

This is a harder problem. If you don’t have access to files and sandpaper, you’ll need to drill something that will fit into your gap to make it bigger. Make sure that whatever you try this with can be held in place firmly without shifting when you apply pressure. Wood, metal, and stone are suitable starting materials for doing this.

If it is a wooden gap, you can make a giant hole by drilling a small pilot hole first to get the center of the circle to show up, then increasing the size of your bit and going through several times to make an even bigger gap. If its metal, you can apply pressure on the drill to make it slip and move around, which will make the hole bigger.

The article went over the various ways on how to drill a hole bigger than your drill bit. One of these methods includes drilling two holes on each side of the material you are trying to bore through. This can be done with any standard electric hand drill and will allow for more torque when pushing against it with your power tool.

Another method involves using an auger-style attachment on your drill, which allows for increased torque at high speeds without damaging the workpiece or its surroundings as much as other options. If you have ever had this problem before, consider reading this blog post to get many solutions. You’ll be happy with the results!
