Making Deadbolt Hole Deeper Or Bigger

The hole saw is a great tool if you intend to cut a reasonably large hole. If you look closely, you will notice a small drill bit at the center of the hole saw. The smaller drill bit is there for a purpose—to drill holes while the saw is working its way through the cut material.

If you have a hole in the door that you want to make deeper or bigger, the hole saw will only move around it. The hole saw will also scratch the door's surface in the process.

You will eventually end up with an oddly shaped hole, which will neither be round nor straight. You may be wondering what to do to ensure you have a smooth cut while making a deadbolt deeper or bigger.

Along with a drill and a couple of hole saws, you will need some scrap pieces of plywood and a couple of clamps. Here is a step-by-step guide on how to have a smooth cut while making a deadbolt deeper or bigger

Step 1: Get The Needed Materials Ready

You will need large and small pieces of scrap plywood for this step. The smaller pieces of scrap plywood are to prevent the clamp from ruining the door.

Step 2: Put The Plywood In Place

Grab a large piece of scrap plywood and place it at the front door. Put a smaller piece of plywood on the opposite side of the door.

Now, tighten your clamp. Ensure it isn't overly tight. Afterward, take hold of a second clamp and another small piece of scrap plywood placed on the opposite side of the door.

Let's call the latter clamp the "top clamp" and the former the "bottom clamp." Tighten the top and bottom clamps to ensure the smaller pieces of scrap plywood are pressed firmly onto the door.

Step 3: Make A Hole

For this step, you will need a hole saw the same size as the previous deadbolt hole. Start drilling from the opposite side of the door (the part with the two small pieces of scrap plywood). This step requires you to pay close attention.

Make sure you stop drilling as soon as the pile driver pokes a hole through a piece of scrap plywood on the opposite side of the door. Next, remove the top clamp, leaving only the bottom clamp in place.

Step 3: Reshuffle Clamps

This step might seem a bit tricky, but the idea is clear. Ensure you take your time on this step. Remove the top clamp, leaving only the bottom clamp in place.

Afterward, place another piece of large scrap plywood at the back of the door (where you drilled the first hole) and reinstall the clamp you just removed.

You must position the new piece of scrap plywood across the hole on the back side of the door. Remove the bottom clamp and let that small piece of scrap plywood fall off. Reinstall the bottom clamp temporarily so it can hold the plywood on the front side of the door.

Then loosen the top clamp so you can reposition the scrap plywood on the back side of the door to cover the hole. It will give you room to clamp both pieces of scrap plywood in place, with one clamp above and the other below the hole in the door.

Step 4: Drill Using A Bigger Hole Saw

Move to the front side of the door and align the drill with the hole. As soon as the drill pokes a hole through a piece of scrap plywood on the opposite side of the door, stop drilling.

Finally, move to the opposite side of the hole, align the drill with the hole you just poked, and complete drilling in the opposite direction.
