Marcrist PG750X Dry Diamond Tile Drill

The Marcrist PG750X dry diamond tile drill is one of those bits that genuinely changes how you approach tiling work. Dry drilling porcelain sounds like a contradiction, but Marcrist has engineered this to work without any water cooling at all. No spray bottles, no wet drill guides, no water running down the wall. You just drill. For anyone who has ever fought with a soggy worktop or tried to keep a tile cool on a vertical surface, that alone is worth the price of admission.

The secret is the wax core inside the bit. As the drill runs, the wax lubricates from the inside out, keeping temperatures manageable and the diamond segments cutting cleanly. It also means the bit is self-sharpening in use, which is why you can get between 30 and 70 holes in grade 5 porcelain from a single bit. That is a serious yield for a consumable at this price point, and grade 5 is about as hard as standard tiles get.

Where the Marcrist PG750X Gets Used

This bit is aimed squarely at tilers, bathroom fitters, and anyone doing porcelain or ceramic work who needs to drill accurately without a water feed setup. It handles all common tile types including porcelain, ceramic, and hard stone. The dry format makes it particularly useful on fitted tiles where getting water into the substrate or wall cavity would cause problems. It is also a strong choice for cordless working on site where setting up a wet drilling rig just is not practical.

The PG750X runs at speeds between 1800 and 3000 rpm and is compatible with both mains and cordless drills. Keep it in that speed range and let the bit do the work. Pressing too hard or running too slow are the two most common causes of premature wear, so a consistent medium pace with steady pressure is the right approach.

Available Sizes

The PG750X range covers 6mm through to 20mm, so you can match the bit to whatever fixings or outlets you are drilling for. Available individually or in sets, with a guide included in certain configurations for those who want a bit more accuracy when starting a hole on a glazed surface.

For contractors working through volume, the Marcrist PG750X dry diamond tile drill delivers repeatable performance across a full day’s work without the faff of water management. Straightforward to use and available in the full size range right here.
