Good value for money!

These are good value but not as heavy and sharp as the real carbide bits I've used in the past! Perfect fit for the work I used them for!

Pros
  • Great price
Cons
  • No instructions

Nice job done! for cutting burrs

I bought them as a last resort to enlarge the tap hole in a porcelain sink. I've only used one of the attachments and while it took a lot of effort it got the job done quite satisfactorily! Happy with my purchase!

Pros
  • handy
Cons
  • I have no particular complaints about it, everything is fine

Cutting Fool in Cutting Grats

I bought these for the price and figured if they didn't work properly I'd just throw them away. I didn't know they were made in China when I bought them but I have to say they work great. I've used them a lot and they're still like new.

Pros
  • Excellent Construction
Cons
  • Requires Socket

Works great on ceramic tile and concrete substrate

Tiler didn't get Moen valve clearance quite right. Bit did a quick and dusty job with the tile and backing. I don't really know how long it will stay sharp because my project is done and they are in a drawer.

Pros
  • Works great for me
Cons
  • Ugly packaging

Good work! The double cut makes a big difference

Great work! The double cut makes a huge difference - when you're driving a corner, a single cut will grab and bounce, making it difficult to get it right, let alone smooth. Double cut, just flip, problem solved. I've only used it a few times so I can't comment on durability.

Pros
  • Quality construction
Cons
  • There are other interesting options.

For $25 you can't go wrong.

If it's real carbide, it's $25. My cordless drill did not convince me, but the drill has a low speed. The teeth are aggressive and the ridges jump a lot. But they bite. They work great on my built in air grinder. They seem to need a few extra turns. Time will tell if they hold up. Just take a look.

Pros
  • Easy Install
Cons
