QEP 5/16 in. Diamond Hole Saw with Water Delivery System

Worked as advertised in porcelain tile. Drilled 6 holes with no issues. Would definitely recommend.

I used a water bottle to keep a constant flow onto the bit and it cut 6 holes, unfortunately I had to buy another bit for the remaining 2 holes.

I needed to drill through very hard tile in my shower as I was installing grab bars. I tried other drill bits but this is the only one that did a good job. I used a corded electric drill. I recommend this product.

The drill bit worked surprisingly well for a cheap diamond bit. I did 2 dozen holes and the last went as well as the first. The box and tape system was a joke, though. Nice idea, but…. I ended up using a spray bottle and tried to control the mess.

We bought the bit to drill holes in ceramic bath tile to attach shower curtain rod but they kept breaking. Could be an issue with our drill but we have yet to find the proper bit. Doing 50 rooms so it’s been a pain.

I purchased the diamond hole saw to drill eight holes through porcelain tile to install shower doors. It met my expectations, and I was completely satisfied with its performance. I believe that eight to ten holes is about the life of the hole saw, but for the price it performed well.

Not sure why the negative reviews on this. Used it to drill four holes for a shower curtain rod without a hitch. Be patient, go slow, make sure your surfaces are clean and dry so the adhesive sticks and you’ll have a gold result, too.

Really happy with the performance of this diamond hole saw. It cut thru the tiles with no problem, giving the tile a good clean and round hole.

When I first saw this I wasn’t sure how good it would work. After using it to install a shelf and sliding glass door in my shower I was amazed how good it work!
