Tools and Hardware Reviews of Hitachi 728023-1/4-Inch Diamond Core Bit with Water Cooling System

Customer Review: Great product
Summary: 5 Stars

I used this to install grab bars in 2 tiled showers. The drill bit and the water reservoir worked great. I have used the triangle shaped bits in the past and all of them broke. This bit drilled 14 holes on porcelain tile and could probably do 14 more. The water helps to keep the bit from overheating and getting dull. It is a little difficult to get a hole started with the reservoir in place. I started the hole first so the bit wouldn't move and then used the resevoir. This product is worth the extra money compared to other tile bits available. Less risk of cracking the tile also.
