Easy Steps to Drill through Metal with a Hand Drill
Drilling through metal may seem like a daunting task, but with a few simple steps and the right tools, it can be a straightforward process. Whether you’re a DIY enthusiast or a professional, knowing how to drill through metal can come in handy for various projects, such as installing shelves or hanging decorations.
First and foremost, it’s essential to choose the correct drill bit for the metal you’ll be drilling. Different types of metal require different drill bits. For softer metals, such as aluminum or brass, a high-speed steel (HSS) drill bit will suffice. However, for harder metals like stainless steel or cast iron, you’ll need a cobalt drill bit, as it is designed to withstand high temperatures and is more durable.
Once you’ve selected the right drill bit, it’s time to prepare the metal surface for drilling. It’s crucial to secure the metal firmly in place using clamps or a vise grip to prevent it from moving during the drilling process. This will ensure accuracy and safety while drilling.
Next, mark the spot where you want to drill using a center punch. This will create a small indentation on the metal surface, allowing the drill bit to stay in place and prevent it from slipping when you start drilling. Make sure to position the center punch precisely where you want the hole to be.
With your metal secured and the center punch mark in place, it’s time to start drilling. Start at a slow speed and apply constant pressure to the drill. Let the drill bit do the work and avoid excessive force, as it can cause the drill bit to break or the metal to warp. As you drill through the metal, periodically release the pressure to remove any metal shavings and cool down the drill bit. This will help prevent overheating and prolong the life of your drill bit.
Drilling through metal with a hand drill doesn’t have to be complicated. By following these easy steps and taking the necessary precautions, you’ll be able to drill through metal like a pro in no time.

Regardless of the method you choose, it is important to ensure that the workpiece is properly secured before you start drilling. This will help to ensure your safety and the accuracy of your drilling.
Apply Lubricant
Applying a lubricant is an important step when drilling through metal with a hand drill. Lubricants help reduce friction and heat buildup, making the drilling process smoother and preventing damage to the drill bit and the metal surface.
There are various types of lubricants that can be used for drilling through metal, including cutting oil, tapping fluid, or even simple household lubricants such as WD-40. Choose a lubricant that is suitable for metal drilling and readily available to you.
Step 1: Prepare the Surface
Before applying the lubricant, make sure the metal surface is clean and free from any debris or rust. Use a cleaning solvent or a wire brush to remove any dirt or rust particles. This will ensure that the lubricant can penetrate the metal surface effectively.
Step 2: Apply the Lubricant
Once the metal surface is clean, apply a small amount of lubricant to the drilling area. You can use a brush or a rag to spread the lubricant evenly. Make sure to cover the entire drilling area and apply a sufficient amount of lubricant. Too much lubricant is better than too little, as it will help keep the drill bit cool and prevent it from overheating.
Step 3: Begin Drilling
After applying the lubricant, you can start drilling. Make sure to use the appropriate drill bit for metal drilling and set your hand drill to the correct speed. The lubricant will help reduce friction, allowing the drill bit to move smoothly through the metal surface.
