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.

How to Make a Door Knob Hole Bigger Without a Drill

Summary: Do you have a door knob that’s too small for your hand to fit through? Here’s how to make the hole bigger without a drill: 1. Cut a piece of cardboard to the same size as your door knob. 2. Trace around the circumference of the knob onto the cardboard, and then cut out the circle. 3. Stick the cardboard onto the door knob, making sure the hole is positioned in the center. 4. Use a pencil to draw a line around the edge of the hole. 5. Use a sharp knife to make the hole bigger than the pencil line. 6. Push the cardboard firmly against the door knob, and then remove the excess cardboard. 7. Put the door knob back on, and enjoy your newly enlarged door knob hole!

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.
  • To avoid any damage in case of an accident during installation, lay some towels or old rags in front of the work area. This will prevent scratches (or worse) on your floor or wall. Always take extra precaution! When removing the tape from around the hole’s edges, be careful not to damage the finish.
  • 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.
  • After you finish installing the doorknob, turn it to see if it moves or makes any rattling sounds. It shouldn’t make any noise. If it does, make sure to fix it before a child uses it, because safety is important. Also, remember to put away your tools and cleaning supplies when you’re done, and to clean up any mess from the project.

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, so it’s important to make sure you do not have anything flammable nearby that may catch on fire. Before starting this project, make sure your work area is clean and you are wearing safety glasses to protect your eyes from wood chips and dust exposure.

You should go slowly while making a doorknob hole bigger without a drill, as it can cause splintering of the wood, which can be dangerous if someone gets hit by one of the pieces. If you live in an older home and plan to replace the hardware for the entire house, it is a good idea to 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. The mortise-hole is bigger and deeper than the 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.

What Is a Double Bore Door?

A double bore door is a type of door where the two doors swing out and are connected by a hinge. This allows for one-way passage in both directions. There are many benefits of using this type of door like:

• It is more convenient to use than traditional doors because you can open them from either side.

• It reduces the risk of injuries from accidents with people or objects that may be passing through when you open the doors as they are not swinging inward on each other.

• It provides better security than traditional doors, with only one opening point for access.

What size hole saw do you need for a doorknob?

A hole saw is a type of circular saw with a single blade and a handle. It is used to cut wood, metal, plastic, or stone holes.

The size of the hole saw depends on the size of the doorknob. For proper installation, a standard-sized doorknob will require a 5/8″ (15 mm) diameter hole saw.

Are Door Handles Standard Sizes?

Door handles are not standard sizes, but there are some common ones that you can choose from. The most common door handle size is between 1-1/4″ and 2″. However, there are some that go up to 2-3/8″ in diameter.

Door Handles Are Not Standard Sizes

What Is the Difference Between Passage and Dummy Door Knobs?

Dummy door knobs are used to create a decorative effect on the front of a door, while passage knobs can be used to create an entranceway.

The main difference between these two types of knob is that passage knobs are made with less material and have a smaller diameter, while dummy knobs are made with more material and have a larger diameter.


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.
