Marcrist PG750X Dry Diamond Tile Drill Kit with Drill Guide

The Marcrist PG750X dry diamond tile drill kit is one of those products that genuinely changes how you approach tiling work on site. No water bottle rigged up with gaffer tape, no wet mess running down the wall, no soaked subfloor. Just a diamond core drill that does what it says, dry, and gets through porcelain and hard stone without fuss. If you’ve spent any time wrestling with wet drilling setups while trying to keep a tile steady, you’ll understand the appeal immediately.

The kit comes complete in a carry case with a drill guide included, which makes a real difference in practice. Keeping the bit perpendicular when you’re starting a hole in a glazed porcelain tile is half the battle. The guide takes that variable out of the equation and helps you start clean and straight, which matters when you’re drilling near grout lines or close to a tile edge.

How the Marcrist PG750X Dry Diamond System Works

The clever part of the PG750X is the wax core inside each drill bit. As the bit heats up from friction, the wax lubricates the inside of the core and helps manage the heat that would otherwise shorten the life of the cutting segment. It’s a self-cooling and self-sharpening system, which means the bit maintains its cutting edge through repeated use without needing any attention from you mid-hole. You’re not going to get 200 holes from a single bit, but Marcrist quote 30 to 70 holes in grade 5 porcelain depending on technique, which is a respectable run for a dry system working through genuinely hard material.

Speed matters here. The recommended operating range is 1800 to 3000 rpm, and staying within that band keeps the wax working properly and the heat manageable. Too slow and you’re grinding rather than cutting. Too fast and you’ll burn through the cooling effect before the bit has done its job. Most cordless drills set to a mid-high speed will land in the right range.

Kit Contents and Compatibility

The PG750X kit includes bits sized 6mm, 8mm, and 10mm, covering the most common fixing and pipe penetration sizes you’ll encounter on a tiling job. The bits fit standard drill chucks, so there’s no adaptor faff, and the system works equally well in a mains drill or a decent cordless. Supplied in a carry case, everything stays together and travels to site without rattling around in the bottom of a bag.

For tilers, bathroom fitters, and anyone regularly working with porcelain or hard ceramic, the Marcrist PG750X dry diamond tile drill kit removes a genuine pain point from the job without asking much in return.
