How to drill a hole in a glass door.

Periodically stop the drill and gently clear the glass dust from the hole with compressed air. Continued drilling through the opposite side until you complete the door knob hole in the door. Once the center bit protrudes through the door stop and switch sides. Certain glass and drill bits require different drill speeds in the drilling technique.

Then insert the lens into the hole from the exterior side of the door. Put the drill bit back into the hole and run it for a few seconds to clean it up and enlarge it very slightly. Insert the barrel into the hole from the interior side and hand thread the viewer together. 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.

The procedure can be long depending on the thickness of the glass and the drill bit needs constant lubrication in order to make it through the glass. Making holes in soft materials like wood is easy. To avoid drilling through both sides of the door wrap the drill bits in masking tape allowing only 1 2 inch of the tip to show. Apply firm pressure as you drill the hole into the door making sure the hole saw is flat and not angled as it goes through the door.

But use this approach on harder materials like metal masonry glass or tile and you ll waste time ruin drill bits and even wreck your workpiece. You just stick a standard drill bit in your drill and pull the trigger. If the barrel fits the hole too tightly to rotate remove it from the hole. To drill holes through glass start by attaching a small piece of tape or cardboard to the glass where you want to drill the hole which will prevent the drill bit from slipping.

Glass can easily be drilled with the correct drill bit and a suitable lubricant coolant.
