Review on 🛁 DrilaxTM Diamond Ceramic Porcelain Bath Fixtures by Adam Browning

later Needed 4 holes for a granite countertop, an "excellent" quality drill bit cost $75 for one size and I had to drill two different size holes. The option was like this, they stretched all 4 holes and probably stretched a few more. Works seamlessly with a cordless drill through 1" thick granite, just add water to lubricate. The coating on the rod peeled off but the diamond cutting zone stayed in place. If I need to do a small project again I will turn to this brand.
