A handy 7 piece mini diamond core tile drill set covering six core drill sizes from 6mm to 18mm, plus a 115mm fine turbo diamond blade. Supplied in a compact blow-moulded case. Suitable for tilers, fixers and confident DIYers.
This 7 piece mini diamond core tile drill set gives you six of the most commonly needed core drill diameters in one compact case, along with a 115mm fine turbo cutting diamond blade. If you’ve ever been halfway through a tiling job and realised you’ve got the wrong size drill knocking about in the back of the van, you’ll understand why a set like this earns its place on site. Everything you need for small-diameter tile drilling, organised and ready to go.
The six mini diamond core drills cover 6mm, 7mm, 8mm, 10mm, 12mm and 18mm. That range handles the overwhelming majority of everyday tile drilling tasks: waste pipe outlets, shower fittings, tap holes, wall plugs behind ceramic, and anything else that needs a clean, accurate hole through tile without cracking it. Diamond core drills cut without percussion, which is exactly what tile needs. No hammer action. You’re grinding through, not bashing through.
What the Mini Diamond Core Tile Drill Set Covers
The included 115mm fine turbo diamond blade runs on a standard angle grinder with a 22.23mm bore, and it’ll cut through most ceramic and masonry products. Fine turbo segments give a cleaner edge than a standard segmented blade, which matters when you’re cutting tiles that are going to be visible in the finished job. A rough edge behind a fitting is one thing; a rough edge on a feature wall is another matter entirely.
The blow-moulded carry case is a practical addition rather than a gimmick. Diamond core drills are fragile relative to what they cost, and rattling around loose in a toolbag is a reliable way to knock the diamond segments off the edge. Keeping them in the case takes about two seconds and means they’ll last considerably longer.
Suitable for Ceramic, Porcelain and Masonry
These drills and the blade are suited to ceramic and porcelain tiles, as well as general masonry where fine holes are needed. Wet drilling with a small amount of water at the cutting point will extend the life of the core drills noticeably. Even a damp sponge held against the tile during drilling makes a real difference. The set works with standard rotary drills and angle grinders. No specialist equipment needed beyond what most tradespeople already carry.
At this price point, the 7 piece mini diamond core tile drill set represents solid value for tilers, bathroom fitters, and multi-trade contractors who want a dependable set without paying for professional-grade cores they’ll use twice a year.
Pro Tip: Always use rotary-only mode when drilling tiles with diamond core drills, never hammer action, even on the lowest setting. Hammer mode will shatter the tile and shorten the life of the drill significantly.
Used primarily by tilers and bathroom fitters drilling through ceramic and porcelain tiles for pipe penetrations, fixture fixings, and outlet holes. Also useful for general masonry drilling where a clean, small-diameter hole is needed without disturbing surrounding material. The included diamond blade covers straight cuts and notches on ceramic tiles, particularly useful when fitting around obstacles like soil pipes or wall outlets where a clean finish matters.

Not suitable for: Not suitable for use with hammer drill mode. These core drills are not designed for hard natural stone such as granite, which requires specialist wet diamond cores rated for stone cutting.
Fit the core drill into a standard rotary drill chuck and set the drill to rotary-only mode. Apply light, steady pressure and keep the drill as perpendicular to the tile surface as possible throughout the cut. Introducing a small amount of water at the drilling point, even from a wet sponge, will reduce heat build-up and extend the life of the diamond segments considerably.
For the diamond blade, fit it to an angle grinder with a 22.23mm bore and allow the blade to reach full speed before contacting the tile. Let the blade do the work. Forcing it through increases the risk of tile cracking and wears the segments unevenly.
Select the correct core drill diameter for your fitting or fixing requirement
Set your drill to rotary mode only, with hammer action completely off
Mark the tile clearly with a pencil or tile marker so you know exactly where to drill
Start the drill at a slight angle to create a small groove, then bring it perpendicular once the diamond has begun to bite
Apply gentle, consistent pressure and keep a damp sponge or small stream of water at the contact point to control heat
Allow the drill to do the work without forcing it through, particularly on porcelain which is harder and more brittle than standard ceramic
For blade cuts, fit the 115mm turbo blade to an angle grinder, bring it to full speed, then guide it through the tile using a straight edge as a guide where accuracy is needed
After use, return all drills to the carry case to protect the diamond edges
Can these core drills be used on porcelain tiles?
Yes, diamond core drills are suitable for porcelain. Porcelain is harder and denser than standard ceramic, so expect a slower cut and use water cooling at the drilling point to protect the diamond segments. Do not force the drill and never use hammer action.
What angle grinder size does the 115mm diamond blade fit?
The blade has a 115mm diameter and a 22.23mm bore, which is the standard arbor size for 115mm angle grinders. This is the most common small grinder size on site, so it should be compatible with most standard 115mm grinders already in use.
The core drills in this set use diamond-tipped cutting edges bonded to steel shanks, designed for rotary drilling through ceramic and porcelain without percussion. The 115mm blade uses a fine turbo segment pattern, which balances cutting speed with edge quality, making it well suited to visible cuts on finished tiles. The blow-moulded case provides a degree of impact protection during transport and storage.
