The Dos and Don’ts of Drilling Steel

Drilling steel can be a challenging process for even the most seasoned DIY enthusiast. While it may seem like a simple task, there are many pitfalls to avoid to ensure a successful outcome. In this article, we’ll discuss the dos and don’ts of drilling steel to help you achieve the results you want.

Select the Right Drill Bit

The first step in drilling steel is to choose the right drill bit. Not all bits are created equal, and using the wrong one can lead to frustration and even damage to your equipment. When drilling steel, it’s best to use high-speed steel (HSS) bits as they’re specifically designed for this type of material. They are heat-resistant and durable, making them ideal for drilling through tough metals.

Keep Your Bits Sharp

A dull drill bit will make your job harder than it needs to be. It will also increase the risk of your drill bit breaking or getting stuck in the steel. Therefore, it’s essential to keep your drill bits sharp. You can do this by regularly using a drill bit sharpener or replacing them when they become too dull.

Use the Right Speed and Pressure

Drilling steel requires a specific combination of speed and pressure to get the job done. If you use too much pressure, your drill bit will become dull quickly, and you risk breaking it or damaging your equipment. On the other hand, if you don’t use enough pressure, you’ll be wasting your time and effort. It’s also essential to use the correct speed setting on your drill. When drilling steel, you’ll want to set your drill to a high speed and use a low pressure.

Use Cutting Fluid

Using cutting fluid when drilling steel is essential. It reduces the friction between the bit and the metal and cools the bit down, which reduces the risk of it becoming dull and breaking. It also helps to prolong the life of your drill bit, making it a worthwhile investment. You can purchase cutting fluid at any hardware store, and it’s easy to apply. Simply pour a small amount onto the steel before you start drilling.

Wear Protective Gear

When drilling steel, you should always wear protective gear. Steel is a tough material, and it’s easy for your drill bit to slip, causing injury. Always wear goggles, a dust mask, and gloves to protect your eyes, lungs, and hands. You should also wear long sleeves and pants to protect your arms and legs. It’s better to be safe than sorry and protect yourself from any potential harm.

Don’t Rush

Patience is key when drilling steel. Rushing the job is a recipe for disaster. When you rush, you increase the risk of making mistakes, breaking your equipment, or injuring yourself. Take your time, work at a steady pace, and double-check your work. It may take longer, but it’s better to drill your steel correctly on the first try than to have to start all over again.

Avoid Using Too Much Heat

Using too much heat when drilling steel is a common mistake and one that can have serious consequences. When you apply too much heat to the steel, it can become warped or even crack. Steel can also become discolored from too much heat, ruining the look of your project. To avoid this, use cutting fluid to keep your drill bit cool and work at a steady pace. If you notice any signs of the steel heating up, stop drilling and allow it to cool down before continuing.


Drilling steel can be a challenging task, but with the right preparation and technique, you can achieve great results. Remember to choose the correct drill bit, keep your bits sharp, use the right speed and pressure, and use cutting fluid. It’s also important to wear protective gear and avoid rushing the job. By following these dos and don’ts, you can drill steel confidently and safely.
