Drilling is one of the basic tasks in the construction and home improvement industry. You can do it on many different materials from wood to tiles. Every little bit of the drilling process counts when you want consistent good outputs for your work.
Yes, pun intended. A drill bit is a little tool, barely a handful but it is crucial in the drilling process. You use it to bore holes into materials, remove layers and more! You can find drill bits in varying sizes and shapes.
The drill bit is a key factor in the success of drilling. If you don’t use the right drill bit or install it right, you risk ruining your work or injuring yourself or others.
The RockHardToolz team presents this beginner’s guide on using drill bits efficiently every time.
In this guide, we shall discuss the following areas of contention:
This is the most important step. You need to choose drill bits that go well with the size and material you will be working on.
A few basic rules are 1/64” method. Do not use a drill bit exactly the size of the hole when working with wood, make it about 1/64” smaller. For other materials, use the correct size.
In order to determine the drill bit size, use a drill bit size card. It is a plastic card with round holes in it and marking on the side. This allows you to size the drill bits easily.
When drilling through the most compact and hard-to-reach spots, use a 90-degree drill attachment.
Keep your drill bits organized so choosing which one to use in each task would be quick and easy.
Once you found the right one, install your drill bit securely to the drill.
Wood is the most common material workmen drill into. In fact, wood drill bits are the most common drill bits in the market.
These bits designed with a pointed tip and spurs on the sides for better capability to bore into the wood. For best results, use drill bits made in coated black oxide.
For metal, you need to choose specially designed metal drill bits. These drill bits have wide angled points. Some metal drill bits are made of regular steel and HSS (High-Speed Steel).
If you want to drill into stone and brick, get masonry drill bits. These are designed with a gentle sloped tip and coated with tough metals such as diamond, hardened steel, and titanium.
Use a carbide-coated drill bit that is especially designed for glass. You can also get drill bits that are made of steel.
Tile can be a bit more difficult to bore through with your drill bit than glass. But you can do it with a masonry drill bit coated in carbide, diamond hard tips and twist drills.
As with any tool, you need to keep your drill bits in top working condition all the time. In this sense, it means that you need to keep a drill bit sharp for every task.
Without a sharp drill bit, your drill is useless. It’s the drill bit that takes all the toll from all the work you do. This makes sharpening it paramount to keep the drilling output to the optimum.
Other reasons why you should sharpen your drill bits? Replacing them is expensive. And you don’t want to risk injuries from blunt drill bits.
Once you determined which bits need sharpening, you need to choose the sharpening tool that fits with your budget, skills, and work routine.
Bench grinders are popular in sharpening drill bits. With this, you can sharpen flat wood, twist bits, masonry, and spur point bits.
It works fast to fix dull and broken bits. However, it is not easy to master.
To sharpen your drill bit with a bench grinder:
A diamond file is the oldest sharpening tool for drill bits but it’s a classic for a reason. It’s cheap, easy to use, lightweight and works on all types of drill bit to provide a precision finish.
You can work them in any direction to sharpen bits such as auger bits, pilot screws, countersink bits and spur points. You can use the tapered end of the file to get into the hard-to-reach places.
But the sharpening takes longer and requires an eye for accuracy.
To sharpen drill bits with a file:
These drill attachments are cheap to buy but effective at transforming your drill into a bit sharpening tool. These lightweight compact tools are easy to set up. But it’s a little limited in what it could sharpen.
Now that you know how to keep a drill bit sharp all the time, it’s time to know and master how to install and change drill bits before every drilling task.
Changing the drill bit is one of the most vital prep parts before every project.
There are three ways to install and change drill bits (keyless drill, with a chuck key, or without a key).
Drill bits do need to be changed on a regular basis, especially if you see visible cracks and the usual signs of wear and tear.
But the most significant reason why you need to change drill bits is the tasks you will work on. Different materials require different specific drill bits.
A keyless drill is your basic drill driver with a threaded chuck that allows you to loosen or tighten the bit into drill just by twisting it on the threads.
To change the drill bit on a keyless drill:
Some drills would come with a chuck key whose purpose of existence is to loosen your chuck and lets you replace the bit.
A chuck key looks similarly to an Allen wrench, but it has a cog that should line up with the teeth of the chuck. A small handle is welded on the end to provide a better grip and improve traction once you start using the key together with the chuck.
To change the drill bit with a chuck key:
In case you lost your chuck key, you can use screwdrivers (cross-slot and slotted) to change your drill bit.
To do this:
Drilling is one of the most significant tasks of any builder, craftsman or tradesman. To do it efficiently, you need to use the right drill bits and practice drilling regularly.
To use drill bits efficiently, you need to sharpen and install it safely every time before you work. Get consistently good output when you have mastered skills and well-maintained tools for your work. This will save you a lot of time and money on the job.
