| Jul 16, 2021 at 3:17 | comment | added | Jim Stewart | Using spade bits I first drilled a pilot hole with a 1/8" bit, followed by the 5/16" spade bit reqd for the plastic anchors I was using. This was for grab bars. Looking at my spade bits right now I wonder if spade bits would drill forward with the drill in reverse, turning counter clockwise? Anybody try that? | |

With porcelain tile I have used the diamond tipped tubular coring bits. Once the hole was started, I would hold the drill with my right (dominant) hand and squirt water on the bit with my left. | |

I finally used glass bits -- look like arrow heads, or the Spade suit on playing cards. They only do 2 or 3 holes in porcelain tiles, and like to be wet, but are cheap enough to be disposable, and are sharp enough not to wander at the start of a hole. | |
