1/4'' Hex Shank Carbide TCT Glass Drill Bits Set
Drilling a hole in glass does not require a specific drill – it just requires the right drill bit. It's important not to use the drill's full power or top speed when you drill a hole in the glass, though. You could end up cracking the glass.

How to Drill a Hole in Glass?
PREPARE THE DRILL
- Fit a variable-speed power drill with a 1/8-inch or 1/4-inch carbide-tipped glass-cutting drill bit
- Don safety goggles, cut-resistant gloves and a mask for protection
DRILL A STARTER HOLE
To prevent glass damage, you must drill a starter hole at the marked point.
- Place the point of the drill at the center of the marked point on the glass
- Pour a few drops of lubricating oil on the area around the drill tip and glass
- Beginning at low speed with medium pressure, drill a small starter hole into the glass
DRILL UP TO DESIRED HOLE SIZE
- Once the starter hole is begun, remove the masking tape
- Continue to drill at the marked point at low speed (about 400 rpm)
- Periodically stop the drill and gently clear the glass dust from the hole with compressed air. Add more lubricating oil as needed to keep the drill point cool
- Stop and replace the drill bit with the next size larger carbide-tipped bit, then continue drilling, lightening up the pressure on the drill with each bit change. Repeat until you have created the hole with the diameter you intend
- Once you have drilled about ¾ of the way through the glass thickness, stop and turn the glass over to the reverse side
- Beginning with the smallest drill bit, repeat the drilling process on the opposite side on low speed with slightly lighter pressure
