What Causes A Big Hole When Drilling?

Doing DIYs or doing maintenance around the home requires drilling most of the time. But you need to be careful and take precautions so that you don’t end up making a hole too big.

Most people learn this the hard way only after they have damaged their walls. We don’t want you to repeat the same. So we have come up with essential tips to avoid disaster while drilling holes in your walls.

  1. Not Understanding The Surface Material: You shouldn’t drill into your walls before understanding the type of material of your wall. Walls are made up of concrete, wood, and drywall. You need to figure out your wall type and choose the drill bit according to your wall type.
  2. Using a Larger Drill Bit: Using a large drill bit is the reason for oversized holes in most cases. So, make sure the drill bit is slightly smaller than the screw.
  3. Vibration: When you are not able to hold your drill rigid enough, there will be vibration which can result in the hole becoming elliptical, tapered, and enlarging the size of the hole. So, hold your drill machine tight enough to avoid vibration.
  4. Drill runout: Drill runout is the condition where the drill bit does not rotate exactly in line with the main axis. Therefore when drilling the bit will rotate eccentrically and will result in a larger hole than the actual size of the drill bit.

What To Do If You Drill A Hole Too Big

Many a time, while drilling a hole it becomes much bigger than the actual required size. Now your screw won’t fit into the hole.

So, in this article, we will go through 10 methods that will give you a wide knowledge of fixing big holes. This will help you solve all your problems.

Method 1: Go For Larger Screws

If you can simply use a larger screw, why go through the hassle of filling the hole or trying to plug the gap to make the screw fit tightly. Just choose a screw thicker so that it will fit into the larger hole.

Make sure the screw is not larger than your hole. If this is the case, you need to increase the size of your hole.

Also, the thicker the screw, the longer it will be. So, before you choose a big screw, make sure it is not too long or too big for whatever you intend to use it

Method 2: Using Toothpicks Or Matchsticks

Filling toothpicks or matchsticks into a big hole is one of the most common and easiest methods used to adjust a hole too big.

Fill the existing hole with glue and insert the toothpicks. Here, the toothpicks will work as shims. Allow for the glue to dry out completely until the toothpicks are well stabilized and tightened in the hole.

Once dried, trim the edges to make the surface flat. Now your large hole is ready to be used again for drilling screws into it.

Method 3: Using Rawl Plugs

Rawl plugs are great to be used on concrete. They act as excellent filler items to be used on large holes in concrete.

Simply insert the rawl plug into the large hole such that it has a very good grip into the hole. Then you can easily drill the required screw into the hole without having to worry about the large hole.

Method 4: Using Wooden Dowels

If your screw will hold more weight, then a wooden dowel will be a better option as compared to toothpicks or rawl plugs.

You just need to find the right size of wooden dowel for the hole. Even if you don’t find the right size of the dowel, you can always increase the hole size such that the dowel fits perfectly.

Remember to insert the glue into the hole before you insert the wooden dowel so that you get a strong grip. Now you can easily drill the screw once the glue dries up.

Method 5: Using Toggle Bolts

Toggle bolts also known as butterfly anchors due to their shape are best suited to be used on hollow walls such as drywalls.

They are also capable of supporting a great amount of load and will be the best option for you if you have made a large hole in your drywall.

Method 6: Using A Hole Repair Kit

If you don’t want to try any of these methods and simply want a ready-made solution to your problem, you can go for a hole repair kit available online.

This type of hole repair kit will fill the hole to screw in again. The kit comes with wall putty, a putty knife, and a sanding pad to fine it down.
