Mini Diamond Core Tile Drills & Blade Set – Wet – 7pc

This mini diamond core drill and blade set gives you six core drill sizes and a fine turbo cutting blade in a single compact kit. Covering 6mm, 7mm, 8mm, 10mm, 12mm and 18mm, it handles the sort of hole-size variety that comes up regularly when tiling — tap holes, shower fittings, wall sockets, overflow outlets and the rest. The mini diamond core format keeps the bits manageable and the kit small enough to throw in a bag without taking up half of it.

The 115mm fine turbo diamond blade is rated for ceramic and masonry, which covers the vast majority of what you will encounter on a typical domestic or light commercial tiling job. Fine turbo segment profiles cut smoothly without the chipping you get from coarser blades, which matters when you are cutting tiles that are already on display.

What the Mini Diamond Core Set Includes

Six mini diamond core drills: 6mm, 7mm, 8mm, 10mm, 12mm and 18mm. One fine turbo diamond cutting blade, 115mm diameter with a 22.23mm bore, compatible with standard small angle grinders. Everything arrives in a blow-moulded case, which is the sort of thing that sounds like a minor detail until you have spent ten minutes fishing loose drill bits out of a toolbag. The case keeps them organised and protects the cutting edges between jobs.

Wet Drilling Only

These are wet-use core drills, which means you need water at the cutting point during use. That keeps the diamonds cool and extends the working life of each bit considerably. A simple water feed bottle or a damp sponge held at the edge works fine for wall tiles. Running them dry will burn out the bond and shorten the life of the bits faster than you might expect.

Described as suitable for both professional and DIY use, this set is a practical option for tilers who want a grab-and-go kit covering the most common hole sizes, without carrying a full set of individual drill bits across multiple jobs.
