Marcrist PG850 Wet Diamond Tile Drilling Starter Kit

The Marcrist PG850 wet diamond tile starter kit is the complete setup for anyone who drills tiles seriously. Whether you are cutting into grade 5 porcelain or softer ceramic wall tiles, everything comes in one place — the drill, the water supply system, the guide, and the fittings. No hunting around for a connector or improvising with a sponge. It is all here, and it all works together.

The PG850 drill bits themselves are where Marcrist makes a case worth hearing. Rather than synthetic diamonds, they use natural South African diamonds. That distinction matters in practice: you can expect up to 700 holes in hard grade 5 porcelain, up to 1500 holes in softer grade 1 porcelain, and as many as 2800 holes in standard ceramic. Those are not marketing numbers plucked from thin air — Marcrist back them with a money-back guarantee. That kind of confidence in a tile drill is not something you see every day.

Wet drilling is mandatory with the PG850 system, and the kit is set up for exactly that. The water swivel with connector feeds cooling water directly through the drill bit while you work, keeping temperatures in check and clearing slurry from the cutting face. It extends bit life considerably and reduces the risk of cracking expensive porcelain. The 1-litre water bottle and 2 metres of 8mm tubing make it easy to set up on site without needing a separate water source.

What the Marcrist PG850 Starter Kit Includes

The Systainer case is worth a mention on its own. It is a proper, organised storage and carry system — not a cardboard box that falls apart after three jobs. Inside you get the 6mm PG850 tile drill, water swivel with connector, 1-litre water bottle, universal plastic drill guide, 2 metres of 8mm tubing, 10mm and 22mm spanners, and a core extraction kit. The plastic drill guide is particularly useful for keeping the bit centred on glazed surfaces where starting a hole cleanly can be the hardest part of the whole job.

This 6mm kit is the starting point. Marcrist sell additional PG850 drill sizes separately, so you can build out the kit around the sizes you actually use rather than buying a fixed set that includes three bits you never touch. Practical, that.
