CUSTOMER REVIEWS

Rated 4.9 out of 5 by 14 reviewers.
Rated 5.0 out of 5.0 by Cuts through tile Project to hang range hood microwave required 5 holes drilled through back splash of ceramic tiles. Tried ordinary masonry carbide tipped bits and was not impressed with my progress after several minutes. "Got to be a better way", yes there is and this is it. Expect the bit to wear down, if you have scores of holes to drill then stock up. March 21, 2015
Rated 5.0 out of 5.0 by Awesome bit, use only cordless drill, and continuous water stream to cool the bit I had to drill 12 holes in ceramic tile to mount two fancy shower curtain rods that my wife mandated as part of two bathroom make overs. Tried the RYOBI glass and tile bit set, it was good for the price, but tile was impossibly hard. After one hole the bit was worn out. So I went to store 6561 and saw the RIGID bit and picked it up. I was a bit skeptical as I had to use my cordless drill for the RIGID as it requires continuous cooling. PROS: - Drills like a champ, but keep the water flowing using a spray bottle set to stream setting. - Cores out the hole in the tile, its amazing, using a small screwdriver I kicked the cores of holes drilled. Perfect cylinders!. -Does not require a lot of power, a regular cordless works fine. Use a low speed setting though and do not press hard. Using an alternating pressure worked best for me. - Does not heat up the tile, that coupled with the lower pressure ,should help prevent cracking of the work. - Worth the price, after 11 holes (First hole was done using the RYOBI). Still looks like it will do another 20 holes (with diminishing returns though). CONS: -Messy, water and tile juice everywhere, not hard to clean up but a watery mess. I put some rags down from hole 3 onward that helped a lot. - Non pointy tip increases the potential of the bit to "run" over the work ruining the finish. (see tip below) TIPS: - The trick is to put some masking tape on the work area before marking the holes. The tape helps the bit get the initial "bite". - Put some rags on the ground to catch the run off. - Fill your sprayer with tap water and get your trusted assistant to do the cooling duty, You can do this alone as well, just spray one pump every ~30 seconds or so when you reduce pressure on the drill. -Start slow and with a lot of control on the drill. Start at an angle to allow the diamonds to bite into the tile then straighten the drill slowly to square angle (90 deg) before the drill goes too far in and hold it steady. Do not wiggle the drill. the bit will make a beautiful straight hole. CAUTION!!: - Use only cordless drills. Corded drills and water are a strict no no. - Wear eye protection, if the bit breaks or the tile splinters........ - Use fresh batteries on your drill. Swap out batteries every two holes or so. - After use wash and dry the bit thoroughly, before storing in the case which it came. January 10, 2012
Rated 5.0 out of 5.0 by Performed as expected I drilled 10 holes in extremely hard German made porcelain tile. The bit did its job well. I’m a woman and did this without any assistance. Here is my tip. I cut a neat bit-size round hole in Gorilla tape (instead of masking tape) so that the bit was confined to start the hole. This tape is reusable even after multiple washes and it also traps enough sprayed water so you won’t need anybody to constantly spray for you. It also catches the splashes other reviewer mentioned. I used the same piece of tape for all 10 holes and washed the chips and sludge off it after each hole. The tape was still usable and sticky when I was done. The result is a neat hole with minimum cleanup and no assistant. September 10, 2012
Rated 5.0 out of 5.0 by Worked like a champ I'm not always good about writing reviews but worth sharing some comments on this one. First, this product worked great on very hard porcelain tile. I used a number of traditional masonry and tile bits with no success (went too slowly, eventually dulled the bits). These bit went through the tile in about 30 seconds. By spraying the bit with water it never heated up at all. I noticed no slowing down from my first cut to my seventh. Finally, these bits are more prone to sliding around when you start the cut. However, the instructions on the back say to start the cut with the bit at a 45 degree angle then level it off. The bits bit into the tile so quickly this way that I was able to position the bit properly without any special tools or tricks. March 27, 2013
Rated 5.0 out of 5.0 by Flippin' Awesome This thing works like a champ, and only 11 bucks! The 45-degree and tilt up technique wasn't diffiicult, and it cuts fast. I can't comment on the longevity, as I only needed to drill six holes. Why mess around with any other type of tile bit? February 25, 2014
Rated 5.0 out of 5.0 by Fantastic bit Another Rigid product that works great. Drilled 22 holes in hard porcelain tiles without this bit showing any wear. The ingenious counterclockwise grove on the bit shank pulls water to the bit head to aid cooling. This is a two person process, I drilled while my wife held a towel under the bit and sprayed water. It took about 2 minutes per hole. I rested the drill battery on the tile to start the hole and then rotated up to 90 degrees. January 15, 2014
Rated 5.0 out of 5.0 by Great Tool for Tile Drilling Installed a shower door mounted on tile frame. Tried a good carbide tip masonary bit. Little use, tile is too hard. Next tried a good spade glass and tile bit, a little better, but not capable of drilling tile either. Tried this bit and was great. Easy to use and works well. Keep lubricated with spray water bottle. Starting a little tricky, use the 45 degree at high speed to make initial scoring of tile and slowly rotate to 90 degrees. May need to empty core about half way on thicker tile. Patience, but this is the correct bit for today's dense tiles. September 5, 2013
Rated 4.0 out of 5.0 by Does the job This product is available in a 1/4-inch version at my Home Depot Store as RIDGID RD-71101, the tool I used. I drilled 8 holes in porcelean bath tile without it showing much wear. The hard part is starting out to make sure the hole ends up in the right place. It takes two people to do the job right, one to operate the drill and the second to apply cooling water. The tool looks in good enough shape to drill another 8 holes in the same kid of tile, if needed. I withdrew the tool every few seconds to help cooling water get into the hole to more effectively cool the cutting end of the bit. January 31, 2012
