I was trying to drill mounting holes in very hard bathroom tiles using my masonry bit. It was not working. I went on line looking for helpful videos and ran across one that recommended the Armeg bit for this situation.The Armeg made a huge difference. I put two layers of masking tap over the planned location of each hole. I used a center punch to put a dimple n the tape where I wanted to start the hole. The Armeg bit was able to start the hole without 'wandering'. Drilling through a  tile still took a few minutes, but finished the job that I hadn't been able to without this bit.

    Great porcelain tile bits!
  

*by J***S on Reviewed in the United States on March 22, 2011*

When I was researching porcelain tile, I found the higher the hardness rating the better.  I went with a 5 rating, but I never considered having to drill into it.  I knew nothing about drilling into porcelain tile.  After trying a masonary bit without so much as a scratch on the tile, I figured I was dealing with some kryptonite space rock.  I started out with a 5/16th hitachi diamond tiped bit, but still couldn't get the 1/4 inch wall anchors to go thru and decided to try the masonary bit again to ream out the hole.  Completely ruined the bit and not a scratch on the tile.  Found these PTC porcelain drill bits and ordered the 3/8th size to the ream out the hole and it worked great.  I can't speak to how they work from the start, but did a great job reaming out these holes.  I used a cordless drill and a emptied out spray bottle with water to keep the bit cool.  The only thing I would change with the design would be to be to put some groves and maybe create a hexigon shape on the bit shaft as it tended to slip in the chuck under preasure using the water for cooling.  Probably wouldn't be an issue in a corded drill where you could use a chuck key to tighten.

Expensive but was one of the few bits that would handle the porcelain tile.
