Drilling is one of the most basic skills in home repairs and decoration. From the simple hanging of picture frames on the wall to building your own wooden cabinet, knowing how to drill properly is very important.
8 Efficient Techniques – How Do You Drill a Perfect Hole in Wood, Metal, Tile or Concrete?
If you have just bought a new drill but don’t know how to use it, Follow these most efficient techniques in drilling holes:
1. Determine the Material of the Object You Are Drilling
There are different tools and techniques needed in drilling holes through different materials such as wood, metal, tile or concrete. Knowing the material of the object you are drilling would influence a lot of factors in the process.
For example, the drill you use for wood may not be effective on concrete walls. You would need a heavy duty hand drill or machine for that.
If you are drilling through a wall, you should use an inspection device to know if there are hidden water pipes or electric cables behind your chosen spot. Many accidents occur when people drill holes through walls without finding out first what’s behind it.
2. Use the Right Type of Drill Bit
After determining the material, you should use the right type and size of drill bit. The size of the drill should match the size of the hole that you want to make.
For example, high-speed steel drill bits are good for drilling metal, but not for concrete objects. If you want to drill heavier materials, you should use cobalt and carbide bits. If you pick the wrong drill bit, you can destroy the material or your drill itself.
You would also not be able to make the right hole. It can be too big or too small. If the size of the hole is incorrect it would be hard for you to fix. Your nails or screw would not be able to fit in properly.
3. Organize Your Tools and Equipment
Once you have chosen your tools and equipment, you should sort them properly into trays or boxes. This can make the process easier and faster.
Drills and measuring tools should be easily within your reach to assure the accuracy of the hole. This can also help you avoid accidents.
Also, before you start drilling make sure that you read and understand the instructions for each tool or equipment that you will use, whether it is a huge drill press or a small hand drill.
You can also prepare trash bins or vacuum cleaners for all the debris that may accumulate after the drilling.
4. Draw a Guide
If you want your hole to be on the spot, you can draw a guide using a pencil. The common technique is to draw cross lines. The intersection of the lines would be the point where you will drill the hole. Just make sure that your measurements are accurate before drilling.
If you have low vision, you might need to use a pen or chalk instead of pencil. Your guide would not be useful if it is not visible.
5. Drill Pilot Holes
After drawing the guides, you can drill pilot holes before drilling bigger ones. You can do this before inserting nails, screws, or bolts.
You should drill pilot holes that are slightly smaller in diameter in comparison with the nail or screw that you plan to use. Pilot holes can help you drill straight and at the right angle.
It can also prevent the drill from slipping on metallic materials. The pilot hole should just be big enough for the tip of the drill bit to fit. Holes that are too large may cause the material to crack.
6. Control The Drill Speed
Good quality drills usually have variable speed function. This allows you to control the speed while drilling. Different materials require different speed rates. For example, you should drill slowly through metals while you should use faster speed on soft wood. Look at the drill’s label.
The manufacturer usually puts instruction on how to control the speed of the drill. As a general rule, you should never go more than the middle speed on the first try.
Start slowly to avoid injuries especially on metals and concrete. Going slowly prevents the drill from slipping and allows you to gain more control of the drill.
7. Drill Straight
his is a basic rule but most people forget to drill straight. Drilling should be at a right angle. This requires precise measurements and concentration.
You can use levelers to keep the drill straight or other straightening tools such as chuck and vise. A chuck is an attachment used for holding a workpiece, machine, or tools such as drills or lathe.
Always make sure the chuck has been properly tightened. This prevents the bit from slipping or spinning while you are drilling.
Some chucks are tightened with a key while others are simply tightened by hand. Meanwhile, a vise is a tool used to secure the object you are going to drill.
This is usually attached to a table and has two flat parts that can be opened and closed using a screw or lever. Metals usually tend to slip while drilling, so this is an important tool to keep your holes straight.
8. Observe Safety Measures
Safety measures should never be neglected. Dust and debris from drilling can irritate your eyes and lungs. Wearing goggles and masks can protect you from these wastes.
Do not attempt to drill anything when you have consumed alcohol or any substance that makes you dizzy. If ever you have a cough or a headache while drilling, stop immediately.
Drills are very important tools in your home kit. If you follow safety measure, you can enjoy using your drill for a longer period of time.
Drilling holes can be fun and easy if you would do it properly. You just have to choose the right tools for specific materials. The most efficient techniques for drilling holes listed above can help you save time and effort. They can also keep you safe from the dangers of drilling.
