States it cuts tile. Does that include porcelain?

Asked by: Phil
YES and No. It cuts through porcelain tiles easy enough but not without some pretty bad chipping of the tile along both sides of the cut. (See my 3 star review for more detail.) Since this is a 4" blade I'm assuming you are using a handheld side grinder. For cutting porcelain with minimal chipping I recommended the Ridgid 4.5 Continuous Rim Blade with Mesh Rim (Model HD-CM45P)

My DeWalt angle grinder is 4-1/2". Will I have any trouble using this 4" blade on small tile jobs?

My DeWalt angle grinder is 4-1/2". Will I have any trouble using this 4" blade on small tile jobs?
Asked by: GDRook
Nope. My grinder is a 4 1/2" Milwaukee. Actually for cutting register vents and outlet box holes in tile I prefer the smaller diameter blades. The smaller diameter works to your advantage when making difficult / complicated cuts because you can cut closer to your cut line. For example... think about how hard it would be to cut a hole for a 4" electrical outlet using a 10"in blade. You would not be able to plunge deep enough to penetrate the backside of the tile before the saw started cutting beyond the top and bottom edges of you guidelines for the hole. When cutting holes for toilet flanges and electrical boxes I prefer a 3 1/2" blade as it allows you to penetrate the backside of tile and cut up to edges of reference cut lines.

4 in. Continuous Diamond Blade is rated 4.3 out of 5 by 114.

The cutting edges of the blade are extremely rough where the cutting diamonds protrude off the side surfaces of the cutting rim. As a result it makes fine chips on both sides of the cut. Making matters worse... what edges aren't chipped as the blade moves down into the cut... get chipped when the back edge of the blade comes back up through the tile. Very disappointed in this blade. The good news is... I went back to Home Depot and found a better solution with the Ridgid 4.5 Continuous Rim Blade with Mesh Rim (Model HD-CM45P) It cost 5 bucks more but delivers a pretty smooth cut in porcelain.
