SHDIATOOL Dry Diamond Drill Core Bit 2pk Diameter 6mm Vacuum Brazed Drilling Porcelain Tile Granite Marble

I used one to drill porcelain tiles in my bathroom, 13 holes to drill, it did it with ease, and definitely could do more, some drills are blunt after 3 holes, very happy!

I've used diamond core drills in the past to do 8mm holes using a drill and each hole took ages to drill. Using this bit in an angle grinder was like a hot knife through butter by comparison. I had a large thick porcelain tile I needed to break out (see photos) the advice was rake out grout and then drill holes to make it easier to smash tile. Only challenge was starting the holes due to the bit tending to run around on the tile. So I used a piece of wood with a V notch taken out to rest the bit in. That did the job! Precision and speed/ I would use one of this bits the next time I need to make holes in a tile and abandon my previous bits.

Bought this 20mm drill to cut two holes in an existing 12mm porcelain floor. I went slow and steady and each hole took about 3mins to cut. Lovely clean edge with no damage to the tile surface. Not sure how many cuts you would get but definitely worth it even if it just does a handful of cuts.

This product was just amazing. This was the third drill bit I purchased as the others were rubbish. First one was from Screwfix there own Erbauer brand Diamond Tile Drill bit laster two holes and the other was Armeg both last two holes each. However this bit cut 28 holes through 20mm porcelain patio tiles no problem. I’ve yet to do the other side but the drill bit doesn’t appear worn. Would highly recommend these to any one drilling through porcelain. Mines were for installing a glass balustrade. Made my life so much easier.

Used for porcelain and ceramic tiles as well as brick. Don’t last forever but cut neat holes with minimal effort

I was scepitcal at first as I have used cheap diamond bits without much success. I even tried a branded Makita 10mm bit which barely cut 3 holes in porcelain tiles before completely wearing down and becoming useless. Thought I would give these a go and after 3 holes, the first bit doesnt look likes its ground down at all... not even opened the second bit yet. Note there is a M14 shank which fits in a grinder. The speed of the grinder is no problem for the bit and it cuts porcelain within seconds. You still have the skidding problem, I made a V with timber to help hold the bit to get started and no problem. Suitably impressed for the money.

Not the best quality but did the job, i doubt they'll last long but they're cheap so you get what you pay for

Second one of these I've bought (first one still going strong but required a smaller size). No need to mess about with water, like a hot knife through butter! Good vfm a 3rd of the price of similar drills from Screwfix etc.

Très bien
