Dry Diamond Core Drill Bit Set,BRSCHNITT 5pcs 6mm Diamond Hole Saw Core Drill Bit with Triangle Shank for Porcelain Tile Ceramic Stone Granite Marble

They do the job of getting through the modern super hard ceramic tiles but you'll be lucky to get more than three holes per drill.

Excellent drilling tiles but make sure you start the drill on its edge and straighten when you have keyed it in.

Used to drill a hole in a window, to remove condensation build up and insert vent. Hole slightly smaller than stated which meant a hard push for the vent. Would still happily use again as both top and base hole presented a clean hole.

These drill bits struggle on porcelain tiles. Bought for the bathroom project but after 5 holes I’d used all 5 drill bits. Had to buy replacement from diy chain to complete the job. Okay for the odd hole but expect to use one drill bit for one hole. The tiles were 10mm porcelain but the drill bits go blunt very quickly even when drilling on a very slow speed.

Pues son las primeras brocas de este estilo que uso en mi vida pero a mi me han dado un resultado perfecto. Hacen lo que prometen. Habré hecho unos 20 agujeros en porcelánico con una broca y está perfecta. Muy recomendable.

Ottime punte. Con una punta riesco a fare 5 o 6 buchi in un attimo

Bom prduto conforme descrito.

works, but wears out fast

C'est pas mal mais il faut appuyer bien fort pour progresser dans le perçage .
