I managed 10 holes in 20mm porcelain slabs before it burned out. Drilled well on my angle grinder. Doesn’t jump around at the start of the drilling as long as you clean the waste from the middle of the bit between holes. I found tapping it with a spanner until the waste came out worked well.
Great tool, did the job intended. I have used 2x to drill 16x 12mm holes on 20mm porcelain tiles. For some reason 1st one burnt out quicker, 2nd one finished the job and still was fine after..I think difference being on 2nd I was cleaning the diamond bit hole from build up twice per hole. Concrete was a childs play for it.
Thank you
This is the second time I have ordered these Mexco Diamond drills (ordered Friday delivered Saturday now thats service). Drilling 20mm porcelain tiles and these go through with ease.
Brilliant product. Made clean holes in 20mm porcelain with little effort.
I was not left wanting with this drill. 18 holes and I reckon I could crank out a couple more! I did use a little water to cool it once the wax was gone.
I was a bit sceptical about buying this as I had several holes to drill in 19mm Porcelain tiles for handrail bolts. I’d always been a Rubi person. Well I was well impressed it managed 32 holes no problem. Highly recommend and a lot cheaper than Runi
