RTC Porcelain Pro Drill Bits

RTC Pro Drill Bit with High Concentration of Diamond for Porcelain

Take the Probit Challenge: Precision Cuts Close to the Edge and Corners

The problem often faced by professionals and handymen alike when tile remodeling or installation is not damaging the existing tile when drilling necessary holes. For instance when you are adding improvements such as shower curtain rods, or drilling new holes to accommodate new plumbing. Imagine yourself having to explain to your customer that you damaged a tile or two; it wouldn't be a major problem unless that tile happened to be an irreplaceable 30 year old tile. In addition to porcelain, ceramic, and natural stone, the Probit also works great on glass & glass tile!

The RTC Porcelain Pro Drill Bit is made of a high concentration of diamond-infused fluted electroplated steel. It also has a very long job life and is rated to make 50 precision cuts into porcelain tile before beginning to lose its precision-cutting ability. RTC Porcelain Pro Drill Bit will make quick and easy work out of your precision cuts close to the edge of tiles as well as tile corners!

Although the RTC Porcelain Pro Drill Bit is specifically designed to cut through porcelain and has a cut life of 50 holes for porcelain tiling, when used properly, these porcelain drill bits are able to cut through ceramic, marble, glass tile, granite, hard PVC, and other hard materials. These bits are not your average diamond hole saw! The difference is that these bits are specially designed and are uniquely superior when compared to the typical hole saw! Included with this Probit is a unique push-rod for clearing debris. This prevents your hole saw from becoming ruined by a piece of tile becoming stuck in it.

Diamond tipped drill bits work when nothing else will!

The drill bits took a bit of getting used to, as unlike all other regular bits.But, they worked on the hardest, thickest, porcelain tiles- which was the objective, as nothing else worked. So, higher price was not a serious consideration. However, I did have to use considerable pressure, and keep the work area wet. I do not think they will last 40-60 drillings. Maybe 5-10 times. But they worked and I finished my project.

Thanks for the detailed and informative review Colin!

Worked like a champ.

Porcelain Drill Bit, 1/8 inch

Worked fine, had to keep adding water to hole.

Well worth it

Not close to 50 holes, but I was going through commercial kitchen floor tile (and the concrete beneath) and it did a fine job with just pouring a small amount of water on it as I drilled. Love the "poker rod" for ejecting the plug, easier than the bits that have a side notch. (eject the plug as soon as you stop drilling; it's harder to get out when it cools off.
