Who knew that a simple beer cap could become a powerful tool? What seemed to be a simple waste, actually hides a trick that has surprised millions of people around the world.

This ingenious, inexpensive homemade method can help you sand, polish, and do small DIY jobs with the help of a power drill and metal cap. Here’s how to take advantage of this trick step by step.

Incredible! Put a beer cap in a drill

🧰 Materials Needed

• 1 beer bottle cap (metal)
• 1 small screw with nut (going through the center of the cap)
• 1 drill bit or adapter
• 1 small piece of sandpaper or abrasive sponge
• Electric Drill

🔧 Steps to follow

1. Preparing the lid
   Clean the lid thoroughly and, if necessary, straighten its edges to avoid irregularities.
2. Drilling the center
   Make a small hole in the center of the lid. If you already have one, enlarge it enough for the screw to go through.
3. Screw
   Mounting Insert the screw through the hole in the lid and tighten a nut on the opposite side to secure it firmly.
4. Placement on the drill
   Clamp the screw into the drill jaw as if it were a normal drill bit.
5. Using the Homemade Attachment
   You can hot glue a piece of sandpaper, abrasive sponge, or even an additional plastic lid if you want to perform other functions such as cleaning or polishing.
6. Turn on and test
   With the drill at low speed, make smooth movements on the surface you want to work on.

💡 Useful tips

• Make sure the lid is well centered to avoid vibrations that could damage the drill or surface.
• Wear gloves and goggles, as metal can spark or come off if not properly secured.
• You can adapt this trick to different tasks: polishing metals, cleaning rust, sanding wood, etc.
• If you use sandpaper, change the piece regularly to maintain efficiency.
• Do not use this method on delicate or electronic surfaces.
