For me, the smaller diamond coated bits are next to useless on porcelain. (6 and 8mm)

Also having to drill 50 holes in a bathroom and have it water cooled at the same time is a messy business.

If making a mess isn’t an issue then I’ll use my Marcrist PG850 with swivel arbor.

I absolutely agree that the vacuum brazed bits aren’t as smooth as the older diamond coated bits when using larger cores.

I’ve not used these ‘red’ vacuum brazed bits yet. I’d imagine they are identical to the gold bits from the same company.

Ali express, diatools seller is the most reputable one with a large selection.

Treated myself to a cordless multi tool, t stack box. A few attachments like dust extractor take off and a depth stop, some sanding pads etc

You’re right, They don’t cut as well as as the cheaper diamond coated bits or whatever they are called. The cheaper bits but the expensive versions of those bits cut nicely with water. That because they are thin walled bits. It really depends on the application though. Towel rad pipes and hot and cold entering a wall mounted cupboard are covered in metal shrouds so it matters less

I mainly use the vacuum brazed M14 bits on the smaller verieties (6mm) and they cut beautifully. Every bit as good as the expensive versions.

On the @ATSDiamondTools website, it says "If you’re looking for a solution for 6,7 & 8mm holes specifically for porcelain tiles we recommend the wax filled bits over these M14 drills."

Would you not agree?

 

[Waluigi]

No I don’t agree. I prefer the M14 wax filled bits over the wax filled bits that go into a drill.

I have tried wax filled standard bits in drills. A few varieties including Marcrist, Spectrum, Mexco, Rubi dry gres with the arbor adaptor and I don’t believe they cut as well in a drill as they do in a Grinder.

This is talking about hard porcelain.

I am however talking about a cordless drill though. That might be the difference

These are the wax filled bits I use

My mate had this. It’s a beast!

I have to put up with my lowly Bosch. The Dewalt has some real grunt that’s for sure.

Be good if you add some feedback on them when you've used them, with images too please.
Started staying clear of the M14 bits, they don’t seem to be cutting clean enough unless you buy high end pieces.
I’ve moved back too the cheapest vacuum braised bits cos they’re leaving cleaner cuts

these are the ones that leave the cleanest holes.
but they cost a bang.
