25mm Diamond Hole Saw with Pilot Bit, 1" Tile Hole Saw with Center Drill Bit for Marble, Granite, Ceramics, Porcelain Tiles, 35mm Depth

Done the job cutting through marble no issues

Works exactly as described. Cut through a granite worktop like butter.

Done a good quick job cutting hole a kitchen sink for taps

Used once and the part melted so poor quality product

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.

Works well for black pvc drain pipe through tile.

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

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!
