LENOX 1-1/4-in Diamond Non-arbored Hole saw

Not as easy as the Youtube videos make it appear.

Product works well if you know how to use it. First off you need to install it on an arbor. Then install the arbor in a 1/2 inch drill motor. Make a guide out of a 2x4 or 2x6 by drilling a properly located hole in the 2x4 (or 2x6) with the hole saw using a drill press. Locate the guide in a location where you want to drill the hole and if you are drilling into a granite countertop flush the saw with water while drilling.

Sharp

I used this bit to drill a hole for a garbage disposal button on my countertop. It made a very clean hole pretty quickly.

Cut right through the tile

Easy to use, quickly cut through the tile took a little bit longer to cut through cement tile backer board

It works, but longevity’s not it’s forte though.

Got the job done, but not as durable as I’d hoped. Halfway through one countertop hole and a tooth broke off even while using water to cool the entire time.

Used with diamond tip arbor bit

Purchased Diamond Holesaw it worked great on a marble countertop.

Have fun.

I had to cut 15 holes through 3/8" thick ceramic tile. My advice - use slow to moderate drill speed, and keep the cutting area wet with water. If you don’t do these two things, you will ruin the cutter pretty quickly. Also it took me about 30 minutes to cut each hole thru the 3/8" tile.
