If you’re working with a heavier piece of steel, you do not have to clamp it down. If you’re drilling through a painted surface, put stir sticks or shims between the clamp and your piece of steel so the clamps don’t dent or scratch the metal.

Use a permanent marker if the pencil doesn’t show up on the steel.

Use a nail if you don’t have a center punch.

Most drill bits are sold in a set with multiple sizes. If your drill bit is dull, it’s not difficult to sharpen the drill bit yourself.

For example, if you want the hole to be 1⁄2 inch (1. 3 cm) at the end, start by drilling a hole that’s 1⁄4 inch (0. 64 cm).

There are 2 different models of drill press that you can purchase. Choose a bench drill press for a compact option that will fit right on your workbench. Pick a floor model drill press if you plan on frequently working with larger pieces of steel. If you plan on offering metal fabrication services to others, consider getting a drill press for the most accuracy.

Spray the steel periodically while you’re drilling to keep it lubricated and reduce friction. Look for a 3-in-1 oil with a telescoping spout so you can lubricate the drill bit as it’s running.

Consider wearing a long-sleeved shirt and closed-toe shoes before working with metal.

Use light, but steady pressure when drilling smaller holes so you don’t break your drill bit. If you’re working with a softer steel, stay consistent at a medium speed so the metal shavings don’t melt. Keep all your clothing away from the drill bit so it doesn’t get caught. The pilot hole is usually smaller than the needed hole. Its function is to remove some of the material, making it easier for the larger drill bits to go straight later. [7] X Research source

The drill may catch on the steel and try to spin in your hands. Keep your face away from the drill in case this happens.

For very large holes, gradually work up towards the diameter you want. It may take 3 or 4 different bits before you have the hole size you want. If you see smoke while you’re drilling, either slow down or use more lubricant. Some drills may have a level built into their body, but if not, use a level to make sure you’re drilling your hole straight.

Never wipe the metal shrapnel with your bare hands since it is sharp and could cut you.
