Dry-use diamond tile drilling and cutting kit for ceramics and porcelain. Includes four core drills, a 115mm diamond blade, M14 to hex adaptor, cooling wax, and a carry case. No water required.
The Mexco 5 piece diamond tile core drill kit is built for tradespeople who regularly work with hard tiles and engineered stone surfaces. Porcelain, ceramic, glass mosaic, granite — these materials punish lesser tooling quickly, and that’s exactly where this kit earns its place. Everything you need for clean drilling and cutting without reaching for a water feed is in one case, ready to go.
Four core drills cover the most common fixing sizes on site: 6mm, 7mm, 18mm, and 25mm. The 6mm and 7mm are your everyday plug-hole sizes for wall tiles. The 18mm and 25mm handle larger penetrations for shower valves, taps, sockets, and similar cutouts where a ragged edge simply isn’t acceptable. All four are dry-use, meaning no water feed is needed during drilling — the cooling wax supplied with the kit does that job instead, keeping the bit temperature down without the mess of a water-fed setup.
What’s in the Mexco Diamond Tile Core Drill Kit
Alongside the four core drills, the kit includes a 115mm UHXCEL Ultra Hard Materials diamond blade. Mexco’s UHXCEL blade is designed for exceptionally clean cuts on hard materials — reduced chipping on porcelain edges is a real benefit here, especially on rectified tiles where a ragged cut edge is visible even after grouting. The M14 thread on the drills fits angle grinders directly, and the included M14 to hex adaptor means you can also run them in a standard high-speed drill. That flexibility is genuinely useful when you’re working in a tight spot where an angle grinder won’t fit comfortably.
The cooling wax supplied with the mexco 5 piece diamond tile core drill kit is not optional — it’s an important part of getting the best life out of the drills. Applied to the rim of the core drill before use, it acts as a dry lubricant, reducing friction and heat buildup that would otherwise burn out the diamond segments prematurely. A small thing, but the difference in drill longevity is noticeable.
The Carry Case
Everything ships in a solid carry case, which keeps the drills organised and protected between jobs. On a busy fit-out where you’re moving between flats or working from a van, having the kit contained rather than rattling loose in a bag is worth more than it sounds.
Suitable for ceramics, porcelain, glass, glazed tiles, and a range of other hard decorative materials, this kit covers the practical needs of tilers, bathroom installers, and general builders working with hard tile finishes day to day.
Pro Tip: Apply the cooling wax generously to the drill rim before each hole and reapply if you feel the bit starting to slow or drag — heat kills diamond tooling faster than anything else, and a ten-second wax top-up is cheaper than a replacement drill.
This kit is used wherever hard tile surfaces need to be drilled or cut cleanly. Bathroom installations are the most obvious application: tap holes, shower valve cutouts, socket positions, and pipe penetrations through tiled walls and floors all call for the kind of clean, chip-free results diamond tooling provides. Porcelain and glazed ceramic are particularly unforgiving materials with standard drill bits, so the core drills in this kit are a practical necessity rather than an optional upgrade.
The 115mm diamond blade suits a range of cutting tasks on hard tiles, engineered stone, and similar materials. Tilers use it for straight cuts and trimming to fit, while builders and fit-out teams reach for it when cutting around obstacles or shaping tiles to profile. The dry-use design suits sites where water feed is inconvenient or impractical.

Not suitable for: Not suitable for drilling masonry, brick, or concrete — these require SDS or carbide-tipped tooling. The core drills are not designed for use without cooling wax, and skipping it will significantly reduce drill life.
Before drilling, apply cooling wax to the rim of the core drill. This is the dry lubricant that replaces water in this system — do not skip it. Mark your hole position clearly, ideally with a tile drill guide or masking tape cross to stop the tip wandering on the glazed surface at the start of the cut.
Begin at a low speed and light pressure, letting the diamond rim establish a clean seat before increasing speed. Angle grinder users should ensure the M14 thread is fully tightened. Drill users should fit the hex adaptor securely before attaching the drill. Reapply wax if the drill slows or the material starts to discolour around the hole.
For cutting with the 115mm blade, fit it to your angle grinder with the arrow matching your grinder's rotation direction. Let the blade do the work — forcing it through hard porcelain increases chipping and wears the blade faster than steady, controlled passes.
Apply cooling wax generously to the rim of the chosen core drill before use
Mark the hole position on the tile surface with a pencil or masking tape cross
Attach the core drill to your M14 angle grinder, or fit the hex adaptor for use with a high-speed drill
Start drilling at low speed with light pressure until the diamond rim seats into the tile surface
Increase speed gradually once the drill has established a clean starting groove
Reapply cooling wax during the drill if resistance increases or heat builds up
For cutting, fit the 115mm UHXCEL blade to your angle grinder, checking the rotation arrow matches the grinder direction
Use steady, controlled passes through the tile rather than forcing the blade through in one go
Store all components in the carry case after use to protect the diamond edges
Do I need to use water when drilling with this kit?
No. All the diamond tools in this kit are designed for dry use. The cooling wax supplied with the kit acts as a dry lubricant to manage heat during drilling. Apply it to the drill rim before starting each hole and top it up during longer cuts. Water is not required and can actually be counterproductive with some dry-rated diamond tooling.
Can I use these drills with a standard cordless drill rather than an angle grinder?
Yes. The core drills have an M14 thread to fit angle grinders directly, but the kit includes an M14 to hex adaptor so you can run them in a standard high-speed drill as well. A drill gives you better speed control in confined spaces, which is useful for smaller holes like the 6mm and 7mm sizes.
The core drills in this kit use sintered diamond segments bonded to a steel body, rated for dry use on ultra-hard materials including fully vitrified porcelain and glazed ceramics. The UHXCEL 115mm blade uses a similar dry-cut diamond matrix, engineered specifically to reduce lateral chipping on hard tile edges. The M14 thread is the standard angle grinder spindle size used across the UK and EU. The hex adaptor allows compatibility with standard drill chucks.
