hey there.
newbie at cutting tile. got a dewalt angle grinder with a dewalt XP4 blade. supposed to be the right blade to cut porcelain. it does a pretty good job but does make little tiny chips on about half of the cut. i've watched a few videos for advice but i dont know what i'm doing wrong exactly.

Might be a combination of the handheld aspect and the blade. The XP4 came stock with my DeWalt tile saw. It didn't impress me. You might want to try a higher quality blade. The problem is that most of those are geared towards wet use, thus shortening their useful life in your application. For longer cuts, you'll get better results with an actual wet saw with a table or a high-quality diamond snap cutter. I only ever used my grinder when doing special cuts (such as circular cuts for openings etc.). You might want to be careful about protecting your lungs when you dry-cut.

Hi, Aaron.

Yeah, most folks that are using an angle grinder for cutting tile are using them for floor tiles where the cut is going to be hidden under a molding or under a door jamb. Almost nobody regularly uses an angle grinder for cuts that will be exposed.

This is best blade I have found for the grinder, the other is awesome for toilet flanges and shower valves I have the silver and gold one. The finger is from another metal cutting blade on a grinder

thanks for the help guys. fortunately, i'm just doing the floor now so i can hide all my cut lines under something.

i borrowed a pretty large manual tile cutter and get a new cutting wheel for it. i can't snap the tile cleanly across to save my life. any tips there? i read all the advice threads i could find on improving technique but there's not a lot on the internet about this for help.
its 24" long porcelain from home depot. thinking i should be able to snap a clean line when cutting...

1/2" base board is your friend. Even pros get scallops. I as m loving my harbor freight diamondback 430$ + new 65$ pearl blade. It has plunge feature.

ended up borrowing a high end wet saw from a good samaritan. should have no more issues with chipping!
thanks for the help everyone
