Cannot withstand prolonged use.

I used these drill bits to drill holes in a tiled shower room to install a heavy sliding glass shower door. The first hole went smoothly, the second not so much. We didn't put a lot of pressure on it. I had to spray water to make the next few holes. Drills may not work for prolonged use. Made what is needed for our DIY project.

Pros
  • Nice to use
Cons
  • old

Works great while staying cool

I use these drill bits to drill a 10mm hole in the bottom of a wine bottle. I first use a 3mm bit to make the starting hole and then open up the 3mm to 10mm. I've drilled over 30 bottles with no problems. Remember to use LOTS of water! I use a bucket of water with a small fountain pump to fill the drill while I'm drilling. The key to success is club and glass cooling.

Pros
  • Quality construction
Cons
  • Requires socket

Impact Drill NOT REQUIRED

I bought these to drill through the cement board of my side yard to secure my 10ft gate. I do NOT have a hammer drill and I figured it would take quite a bit of work and gradually increasing the size of the drill bit to get the required 1/2 hole diameter. I was wrong. Using my Milwaukee M18 FUEL Driver, I finished the hole in less than 20 seconds. I didn't even have to cool the racquet with water. I highly recommend these rocks. Can't comment on durability as I only had to drill one hole but…

Pros
  • Best in the niche
Cons
  • I will add later
