4 1/2 Inch (115mm) Diamond Hole Saw with Pilot Bit, 4.5 Inch Tile Hole Saw with Center Drill Bit for Marble, Quartz, Granite, Ceramics,Porcelain, 1-1/2 Depth of Cut for Thick Countertops

I used it for drilling kitchen countertop which is quartz and the drilling was ease

We bought this to make holes on ceramic pots. It does the job well

I have a handyman business and I had a customer that needed an outlet mounted in a quartz countertop. I was planning on buying a hole saw at HD and scoffed at the price since I'd likely only need the saw for an occasional job. I took a chance on this saw and I was pleasantly surprised at how well the pilot bit worked and how well the hole saw cut. I made a water dam out of some plumbers putty and it kept the saw cool. After using the saw, I cleaned and inspected and it looks brand new.

Ich habe mehrere Löcher in Steingutfliesen gebohrt. Hat prima funktioniert. Keine Beanstandungen.

Works for quartz countertop. I seen another review saying it worked so decided to give it a try. It took about 10 mins with cordless drill on slow speed gear setting and light to moderate pushing pressure. I added water to the hole being cut every 1 minute to cool and lubricate the bit. Nice very clean cut hole and the hole saw still looks and feels like new. Good quality!

I have only used once on a piece of granite countertop. It appears to have plenty of life for future use. It cut easily and fast with water. The thickness helps to go all the way through entire piece of granite - it was close. Worth the money.

Used on Hardy board... worked well
