How to Make a Door Knob Hole Bigger Without a Drill


A doorknob can be an instrumental part of any door, which helps keep the door closed and secure. However, when there are too many people inside the home, or if you have items kept in your attic or basement and not touched for long periods of time, these areas tend to get dustier over time. This means that the knobs on those doors may start to look duller than they used to be. One way to help replace this is by making them bigger, as this will allow more light and air into the room behind it – thus helping it become easier to clean at all times. But replacing is always not the option. And sometimes scarcity of materials can require adopting other methods. So today, I am going to discuss a process on how to make a door knob hole bigger without a drill.

Step-wise Guide How to Make a Door Knob Hole Bigger Without a Drill

  • Make sure to measure the diameter of your doorknob before buying it, and make sure that you get the right size.
  • Buy a pack of free-size steel washers at a hardware store near you. The diameter of the steel washer should be slightly bigger than the actual measurement of your doorknob hole (the door hole is not necessarily round).
  • Screw in the two screws on both sides of your doorknob hole, but not too tightly because they are supposed to remain loose later on. A loose screw will allow enough space for movement when positioning one side of a larger diameter metal washer underneath it.
  • Insert one side of a larger diameter metal washer nicely into place inside a loosened screw head.
  • Gently tighten the two loose screws back into their original positions until you feel a little bit of pressure to hold down the metal washer in place better inside the screw head.
  • Ensure that your doorknob can still spin easily when turning and moving smoothly after putting everything together.
  • 7 . Re-install your doorknob onto the hole on your door.
  • Lay some towels or old rags in front of where you are working to protect any damage if there is an accident during installation; this idea will prevent scratches (or worse) from happening to your floor or wall because of carelessness during installation. Extra precaution is always good! Be careful when removing the tape from around the hole’s edges that you made for your doorknob!
  • Screw in your new doorknob inside the hole after replacing the tape onto it, then try to move it around and test how well it works. It should now be easy to turn and operate correctly with no obstruction from the metal washer. The added thickness will make this technique work just perfect if you are not planning to drill a bigger hole on your door surface. If there is any wobble or rattling sound when turning, loosen up all screws on both sides of the doorknob slowly until the movement is smooth again; then re-tighten those screws even more securely after putting everything together nicely into place. You might need to repeat these steps several times before getting it right.
  • If you are done with the installation, turn on your doorknob to test it for any movement or rattling sound that should not be there, especially if a child will use it later on. After all, safety is important for everyone! Ensure to put everything away and clean up after any mess related to this project before going out again! Put away tools and cleaning supplies until next time when you need them again.

Precautions While Learning How to Make a Door Knob Hole Bigger Without a Drill

Make sure there are no children or pets in the room where you will be working. The hole saws make a lot of noise and can also throw out wood chips, making sure you do not have anything flammable nearby that may catch on fire. Make sure your work area is clean before starting this project. Wear safety glasses to protect your eyes from fall wood chips and dust exposure. 

Go slowly while making a doorknob hole bigger without a drill, as it can cause splintering of the wood, causing injury or even death if someone gets hit by one of them. If you live in an older home and plan to replace the hardware for the entire house, buy new doorknobs with all-metal shanks. If your doorknob has a broken or missing screw, you can replace it with a new one.

There are two types of holes in the handrail, the “through-hole” and the “mortise hole.” The through-hole is a small hole drilled vertically from the top to the bottom part of a handrail while bored at an angle of 90 degrees to its axis. In contrast with this type of hole, a mortise-hole is bigger and deeper than that of a through-hole and is made by cutting vertically and horizontally to form an inverted ‘T’ shape beneath the rail itself. This prevents any harsh edges if anyone falls on or against it, which could lead to accidents.

How Can You Cut Holes in Metal Without Seeing Behind It?

The best way to make a circle or any other difficult shape from sheet metal is using special plastic reinforced shears. With these tools, you can figure out the measurements and then punch through metal with little trouble. However, sometimes you need to enlarge holes already made in sheet metal objects like cabinets or electrical boxes so they’ll fit over new hinges or doorknobs. Luckily some ways also don’t involve buying special tools.

Cut Holes In Metal

For Sheet Metal: Use a Dremel and a Grinding Stone

If you’re working with sheet metal, the easiest way to make the hole bigger is to use an electric drill equipped with a grinding stone. These are much like sandpaper in that they have thousands of small abrasive particles that scrape up and away from the cutting tool. The trick is to find the right amount of pressure needed when using this method, so you don’t cut completely through one side or glue both pieces together by accident.

You’ll also need a steady hand for this kind of job since it’s difficult to judge how far back to hold the drill bit from the surface of your workpiece. For best results, use larger grit stones that will cut slowly and give you time to judge your progress. When possible, use a metal-cutting blade instead of a grinding stone to cut completely through the piece instead of leaving behind an edge.

If You Don’t Have a Dremel: Use Tin Snips or Sheet Metal Cutters

If you don’t have access to an electric drill and grinding stone, consider using tin snips or sheet metal shears to cut holes in metals. While these tools can be used together to make exact cuts, they’re not meant for shaping the material into complex designs like circles. Instead, opt for using one tool at a time by starting with standard tin snips before moving on to sharper shears if need be.


Naturally, knowing how to make a door knob hole bigger without a drill should be more of an option than not doing so. This knowledge helps prevent injury and death from happening if those little ones or pets play in the area working on this project. Make sure they stay away from you while making the doorknob hole bigger without a drill is taking place. Also, use safety glasses to protect your eyes from dust exposure and chip contact while working on this project.
