For the DIYers, a time will come when you'll need to drill into a piece of metal. It may seem like a daunting task, but it really isn't that difficult. All you need to know is the best way to perform such a task, and you should equip yourself with all the relevant techniques and skills. Though experience is undoubtedly irreplaceable, it's worth starting your projects armed with the right knowledge. So if you're about to drill metal, or your planning on doing a similar task, then here are some amazing tips to help you out.
Create a Dimple
When starting your drilling, you'll need to first make a dimple on the metal surface. This is simply a tiny indentation that will hold the drill bits in place and prevent them from wandering off. Mark off where you want the hole and then using a hammer, knock a centre punch into the metal. This will create a tiny aperture for your drill. The hole doesn't have to be huge, just a tiny aperture would do. That way the tip of the drill can have an area to ride on, and in addition, you'll end up with a straighter hole.
Watch Your Drill Speed
For first timers, being in control of the speed is paramount. You don't want to start your project and then visit the hospital a minute later. Use a slow speed because that gives you better control over the drill and allows you to perform a steady job. Using faster speeds may cause the metal to buckle, and the drill may slip and injure you. So relax, and take it slow.
Lubrication Equals Durability
If you are going to be doing a lot of drilling, then it's worth lubricating your bits. Lubrication is really important particularly when you're going to be working on deep holes. There are many lubricants out there, but try going for a multipurpose one for a better experience. Applying oils on your bits minimizes the friction and prevents heat from eating up the bits. That causes them to last a lot longer.
Even in your die hard projects, don't forget to apply the necessary safety precautions. Never start drilling if you've not put on safety equipment. Goggles for instance, are a must have, because they protect the little bits of stray metal from injuring your eyes. Gloves are also a necessary tool for hand protection. Try and put them on whenever possible.
