How to Drill Plexiglass

Drilling a hole in Plexiglass is accomplished with a power drill, and a sharp or metal drill bit. Plexiglass can crack and break, similar to glass during the cutting process. Properly securing the Plexiglass with a clamp, and reducing drill friction are key elements of successfully drilling a hole in a piece of Plexiglass.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Plexiglass
• Power drill
• Drill bit (Metal or steel piercing bits work best. Glass and tile drill bits are also highly recommended.)
• Sandpaper, or power sander.
• Clamps to secure Plexiglass while drilling
• Water
• Safety eyewear and gloves
• Level work surface

1. Place Plexiglass on a flat and level surface. Clamp or otherwise firmly secure Plexiglass in place.

2. Measure and mark portion of the Plexiglass for drilling.

3. Wrap masking tape around top and bottom of marked drilling area. Mark masking tape for drilling if Plexiglass marking isn't visible.

4. Drill hole using a high speed steel or metal piercing drill bit. Glass or tile piercing drill bits also recommended.

5. Sprinkle water lightly as needed to reduce heat and friction while drilling.

Tips & Warnings

• Use 1/4-inch drill bits for Plexiglass holes up to 1 inch in diameter. Use a paddle drill bit for larger holes.
