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!
