In the end, drilling through metal is no different from drilling into wood. You must position the drill in place, press the button and press the drill against the material to be drilled. However, there are two main differences. The drill material needs to be stronger and you have to protect yourself from chips and sparks. Pieces of metal are sharper and can hurt a lot more than sawdust and pieces of wood.
Steps
Step 1. Select the right drill for the job
High speed steel drills will work with most metals as well as titanium coated carbon steel. For very hard metals, use a cobalt steel drill.
Step 2. Fasten the part to be drilled in a vise in your workshop
This step is not necessary if you are drilling a large steel object such as a wall or beam.
Step 3. Mark the location to be drilled with a pencil
Accurately measure the area as it is more difficult to correct an error in metal than in wood.
Step 4. Place the nail in place of the pencil mark
Tap it a little with the hammer to mark the drill location and create a starting dowel.
Step 5. Keep your fire extinguisher within reach
Chances are slim, but sparks released by piercing metal can cause small fires. Having a fire extinguisher nearby will help contain potential fires.
Step 6. Put on your goggles to protect your eyes from sparks and any flying debris
You may also want to wear long sleeves with a closed collar for the same reasons.
Step 7. Position the drill on the made bolt
Adjust the angle too. Newer models will have level bubbles to help with this.
Step 8. Apply firm pressure to the metal being pierced
For harder metals, drill slowly and steadily. Softer metals need to be drilled faster as it can melt if you take too long. Even in these cases, don't use higher-than-average speeds.
Step 9. Remove the bit immediately after reaching the desired depth
Allow it to rotate until it is completely removed from the metal.
