Diamond Hole Saw Kit 17PCS Tile Drill Bits Sets with Double Suction Cups Hole Saw Guide Jig Fixture from 6 mm-50 mm Hollow Drill Hole Saw Set for Ceramic, Glass, Tile, Porcelain, Marble, Granite

Works as described and has great suction.

Drill guide works as expected and included bits worked better than my Milwaukee hole bit.

Bought these to drill holes in porcelain tile, and they did a pretty good job of it, especially for the price, which was a lot less than local stores were charging. It gave a pretty clean cut once I remembered to wet down the surface, which I had forgotten at first, LOL. You will want to make sure you squirt water around the area before and periodically during drilling your hole. This keeps the saw from overheating and preserves the diamond surface from wearing off too quickly. (It will still wear off, just not as fast.) If you're drilling porcelain, I'd say you can probably count on getting no more than 3-4 holes out of a blade before it wears out. On something softer like ceramic it should last a bit longer. If you are used to drilling with wood hole saws, you'll notice that there is no center bit to make a pilot hole on this one. (It's done differently on hard surfaces.) You have to start on an angle & wobble around in a circle as you start your cut until it builds a groove. There are more sizes included in the set than I will probably ever use, and the more popular sizes will need to be replaced periodically, but I chose this set primarily because of the jig with the suction cups, which I feel will come in handy starting the holes on my shower walls. So far, I've only used it on floor tile, where the downward pressure makes it less likely to "skip" across the surface. I will try to update this review when I've had the opportunity to use the jig.

For the money, this is worth every penny. Used this on two tiling jobs. Very easy to use and gives extremely professional looking results. Perfect for creating inside radii, holes for plumbing, and cutting a core through a tile to install wall anchors for shower curtain rods.

Drill bits don’t last long

Very good what's actually

This is an alternative if you want to save money and want a single job done. This wont last and it barely cuts trough porcelain tile. disappointing purchase overall.

Muy buen producto
