Review on 🔍 DrilaxTM Diamond Drill Bit Cutting Tools for Hole Saws & Accessories - Optimize Your Search! by Justin Miller

The quality of the bits is pretty good for the price. These bits won't cut very many holes. But it should be fairly obvious from the price point. A good quality Bosch will cost you 2-3 times as much My problem with these bits is that they aren't deep enough to drill through a 1" thick granite slab. Sure, I read in the product description that they actually cut 1 1/4" thick material. This is what we typically refer to as 3cm material in the US. Hit the center of the ball with a hammer and dowel. Not perfect and might break the granite I got lucky and it worked with the minimum ly damage. These nozzles are suitable for 2 cm thick tiles and natural stone.
