What Customers Are Saying
This diamond-coated drill bit performs well for drilling clean holes through ceramic, glass, and tile materials, especially when used with water to keep the bit cool. However, it can be challenging to start the hole and keep the bit steady, particularly on porcelain tiles. Users recommend starting the hole at an angle, gradually straightening the bit as it cuts, and using a low drill speed. The bit may wear down quickly, especially on thicker or harder materials, so it's best suited for light to moderate use.

Didn’t last.
Would Not RecommendThe bit couldn’t handle the heat and got completely bent/twisted after just a few holes even though I was using water to cool occasionally.

Done in One (hole)
Would Not RecommendThis bit's hollow shaft bent halfway through 5/16" thick ceramic tile, rendering it useless for a 2nd hole, same as described by a user 1-year ago. Very disappointed, particularly as it was recommended by the department's staff member (who was otherwise helpful).

Beware of Cobalt diamond drill bits.
Would Not RecommendProduct did not hold up At all or as described on the the packaging. Initially I bought two “Just in case”! Well I needed the second one and had to return for a third one! They all failed, two which broke off in the hole clogging the hole I needed to install an anchor bolt. I had holes to bore and had to finish them off with masonry bit using brawn in lieu of a sharp bit.

drill press maybe?
Would Not Recommendwithout a "starter" pilot hole, this will not work. Might work with a drill press, but not with a hand drill

No Issues at all! KNOW what your doing!
Would RecommendI have drilled 6 holes in porcelain with this bit so far and it looks the same as it did out of the package. The bad comments are from people who have no idea of the concept of drilling in concrete and tile...sorry not sorry! Put your battery screwgun on LOW speed and have a squirt bottle of water ready...the bit must remain COOL during drilling, and that's what the water is for. As soon as you break the surface of the tile by drilling on a slight angle, have someone squirt water on the bit th...
Awesome at drilling throug ceramic tile already up
Would RecommendGreat product! Drilled hole in tile as described.
From 5_SLASH_16-in Wet_SLASH_Dry Diamond Core Drill Bit for Stone Verified Purchaser
Worked great
Would RecommendI think the negative reviews are from people who didn’t know what they were doing because this worked perfectly on porcelain tile. Start at high speed at 45 degree angle and gradually move to straight on. Spray consistently with water while drilling and clean out the hollow bit too. Drilled 8 holes and could have continued drilling with no problem
