This morning I installed a new shower door requiring 12 1/4" holes drilled in the 1" sq glass mosaic tile walls. Glass mosaic tile is hard to drill. I have put together a small arsenal of tile drills that make the job go easy.
I could "get by" with one drill but the job goes a lot better with three. In the picture below:
1. Top is a Kobalt carbide drill. It is very easy to start the hole with, especially if you put a couple thicknesses of scotch tape on the tile which helps keep the drill from skating and lets you see your mark. But the Kobalt is extremely slow at drilling.
2. Middle is a Bosch carbide drill. It has a different profile and drills very fast but is much harder to start than the Kobalt. Also, when the nose breaks through the back of the tile, the Bosch starts to vibrate and hammer badly risking chipping or breakage.
3. The bottom is a Milwaukee diamond hole saw. It is hard to start and slow to drill. It is also difficult to remove the glass core which has to be removed often so the drill will continue to remove material. But the big advantage is using it at the bottom of the hole, it goes through smoothly with no danger of chipping.
So using the three in sequence makes for a faster and better job than if I wanted to "get by" with just one.
Thank you for the great tip on drilling. I need to install a glass door in our guest bath shower that I recently remodeled. Everything else done but the door!
