Bosch T130DG 1-Piece 3-1/4 In. 30 Grit Diamond for Hard Tile T-Shank Jig Saw Blades

I had to cut a circle of around 15in in diameter on a hardiboard (used in bathrooms as waterproof backing before installing tiles) for a mosaic project. I did a jig to ensure that jigsaw was guided all the time. The material is about 3/8 to 1/2 inch thick and this blade had no trouble cutting through it. On my first try the cut was perfectly straight however the circle was still too big and I had to cut back about a 1/4 inch. When trying to remove this little strip the blade slided laterally so the cut was not perfectly straight. I dont think this is an issue with the blade it just happens that there is little material on the outside to keep the blade straight. Lesson to be learned... cut with enough material outside the cut so it helps keeping blade straight and allow for some gap so the circle will fit in a metal enclosure.

I've been adding a bathroom to my basement and found a fantastic 12x24 tile at the Re-Store.Great quality, porcelain, the down side of a porcelain tile is, It's Hard. Meaning you can't just cut it like a ceramic tile, you need diamond blades and bits. I started out using my Roto Zip with a diamond blade to cut out shower fixtures, and that turned out to be a chore, used a $20 diamond bit, and it took about 20 min to get the handle cut out.So when it came time to cut the toilet flange out, i went a different direction. I found this diamond jig saw blade for hard tile, perfect for my cordless jigsaw. I did a little research, you don't want to cut porcelain tile dry, all you will do is over heat the blade and dull it or even worst break it. So the trick I found was to fill a small bucket to the rim with water and place the tile on top of it so the blade goes through into the water. cut slow with moderate pressure. This blade did the job in 1/4 of the time with no effort and no dust. cut the circle out perfect!If your working with Hard Tile this is the blade for the job!

It cuts through the ceramic tiles. It struggles, it needs to be kept wet, it is slow to do so, it causes chips in the surface but it gets the job done. If all you need to do is to widen the hole just a bit to fit that pipe through the tile or make some odd shape that will have the edge covered with a trim this is the way to go. Just keep your expectations reasonable - it ain't no wet saw or even diamond blade on angle grinder. I've made a total of about 12-14 inches of cuts in pretty hard tiles so far and it still holds - keep it cool (watered) to make it last.

Writhed great to clean up inside corners after cutting tile with a tile saw

Well made but still has a hard time cutting ceramic tile.

This Jig Saw Blade works perfectly on Ceramic Tile. You'll need to take it a little slow, especially on thin Tile; Otherwise the Tile could Crack if you try to rush it. I'm very pleased with it. Cut on the top side of the Tile or it will be more likely to crack. It leaves a perfectly SMOOTH cut.

I used this to trim ceramic tile in a bathroom It made cuts quite nicely.

I was using a regular jigsaw bladeFor cutting plastic :) yea I knowBUT then I got this and life because easier
