ToolocitySCB0134D 1-3/4-Inch Monster Dry/Wet Diamond Granite/Concrete Core Drill Bits/Hole Saws

Easy and well worth money.. mostly buy Milwaukee brand or dewalt brand for tile cutting holes.. but they only last 1 cut if that.. this thing is going to last me many jobs and many cuts.. welll worth the money

I'm a general contractor that specializes in tile work, and I do a lot of bathrooms and kitchens, and I have to drill or cut a lot of holes. I have a handful of these in difference sizes and each one has worked for me time and time again and given me consident results. I use a wet sponge and routinely wet the drill hole. I use a porter cable single speed grinder.

Love this thing. Bought two sizes. Unfortunately, the first order “disappeared somewhere on route”. We lost time and money on a job because of it but Amazon gave me a $10 coupon for my trouble. WooHoo. It cost me about $500 due to a delay on ourJob. All is well in the end.

I am very pleased with this tool it got the job done and I am considering buying a complete assorted set .

VERY difficult too get a clean cut. You almost need a drill press to make this work. Attempted to make a drain cut into Honey Onyx for a vessel sink. Thankfully I started the hole from behind the bowl, and the mounting ring of the sink covered the gigantic area that it made. Not recommended for the weekend warrior or occasional 'do it yourself' person. I tried starting the hole at an angle, it made quite a mess, and scored a 10 on the difficulty stage. Not recommended, especially for the price. Hire an expert for what this drill bit costs, and ESPECIALLY if you need a clean cut. Good luck.

Works great with my wet grinder. It went through my concrete countertop like a hot knife through butter!! It barely shows any signs of wear. This is going to be a staple in my tool arsenal for years to come!!

Great Core bit for the money. We get a lot of use out of it.

Easy to use, made a guild with scrap plywood.
