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
