How to Drill Accurate Holes in Tile and Masonry

Accurate holes in tile and masonry come down to control, not force. A few habits keep every hole where you want it. Here is how.

Position before you power up

Mark the spot and steady the bit before pulling the trigger. A slant or eccentric head helps here, since it resists sliding across slick glazed surfaces at the start.

Match method to material

Softer stock like wood, brick, and cement drills dry. Hard tile, porcelain, and marble need water or coolant to protect the tip and keep the cut clean.

Choose a carbide tip

Masonry and tile chew up soft bits. Tungsten carbide tips resist abrasion on dense surfaces. An eccentric tile drill bit set pairs that tip with a positioning head for tricky starts.

Set the right speed

Follow the maker's guidance, often at least 2000 RPM. Steady pressure beats brute force, which only builds heat and shortens the life of any bit.

Watch for hidden hazards

In concrete, avoid embedded reinforcing steel, which can grab a bit and ruin a cut. Scan the wall and plan your hole placement around it.

The bottom line

Position first, match wet or dry to the material, use carbide, and control speed. Follow those and accurate holes in tile or masonry stop being a gamble.
