How to Mark Blind Holes for Drilling: 7 Methods
Although drilling into something is not very unfamiliar but what if you have to drill into an unknown hole? Sounds a bit overwhelming right? Well, we have tips and tricks for you so that the process becomes easier.
However, the process would be effortlessly good if you can use the best drills for the job.
There are a few tricks that would guide you to the unknown hole. In fact, you would know how to drill on the right place. And it’s quite simple to follow those. Let us know the tricks in detail in the following attachment.
Method 1: Through a Small Pilot Hole
If there is any sharp object available around, you can probe the hole. You can probe all the surfaces until your hit the ground. Once you detect the surface, you can use a pointer to mark that place.
As a sharp object, you can use anything like a pin, nail, knife, or something which has a sharp edge. If you have a smaller drill bit available, that would work great.
Using that you can drill narrow holes around the specific surface. That way you would have an idea of where the actual hole should be placed.
Method 2: Probing With a Sharp Object & Using a Chisel
If there is no sharp object available around, you can go for a knife or chisel. Using those you can mark the drill location better.
First, try to strike the surface gently with an object. That would help you to understand the hollowness of the surface. And then use a marker or pencil to point the surface around.
Be careful while using a chisel or knife as there is a chance of the wood getting damaged.
Method 3: Using A String
If you cannot find anything around, you can use a string. Using that you can mark the location of the drill. Tie one end of the string with the drill bit and place the other end against the wall.
The pencil will guide you to the wall to mark the place. And that’s how you get the answer to how to mark holes for drilling. Again you have to be very careful while doing that. So that you don’t hit any wiring while drilling.
Method 4: Using Screwdriver and Find the Middle Hole
If you cannot manage to punch you can go for a screwdriver. Even nails will also work in this case.
First, you have to make a small hole in the center with the help of a drill. Next, you can use the screwdriver to detect the existence of the metal. But do not drill too deep, that might damage the surface.
Once you figured out the center of the hole, insert the screwdriver. The screwdriver will guide you through the drill place. This will also help you to figure out if your screws are straight or not.
If you are using the hand drill then keep the level in control. This step is more vital for drilling a flat surface.
Method 5: Using Wire or Bent Paper Chip
Another very handy and convenient way to locate the drill is to use vented paper or small wire. First, decide the place where you want to drill. Poke the place deeper with the help of a wire or paper chip.
These will help you to detect how deep you can drill. This step is a bit riskier. While drilling, you have to keep the machine straight.
Otherwise, it might harm the surface.
To avoid any risk you can also take the help of tape at the mouth of the hole. That will hold the wire in the right place.
Method 6: Insert Other Ancho
When you are drilling into something where there is no guide or noticeable pointer it’s quite difficult. You at least want a guide where the drilling can be done smoothly. So for those cases, a bolt or anchor point really helps.
Insert a bolt or an anchor point through the hole and use it as a guide. That will ensure the correctness of the drilling place.
Method 7: Making A Template Using Cardboard
Using a cardboard template really helps in order to guide drilling. If you have a piece of cardboard the same size as the hole, use it as a template. It will help to mark the drill location.
First, mark the cardboard locating the center of the hole. Then you have to mark around the hole. And to have an equal measurement around, take the help of a ruler.
Now connect the mark with a straight line.
That way you have the guide of the marking line for drilling. You can also follow the same steps if your question is how to drill mounting holes.
Sometimes it will also be helpful for uneven wood cutting.
