These work better than some Milwaukee tile bits, I use these a lot in commercial plumbing for finish fixtures and trim, well worth the purchase. Also helps to go slow and apply a little water so you don’t dull it.

Bought these on a whim trying to save alittle money, haven't gone back to any other bit since. Love them so much I've convinced my work to also buy them for some of our install crews.Bit tip to these sucker's though, be sure you cool your bit per hole drilled. Including wetting it on the initial holes, I've had a few snap from being impatient with a hammer drill.

Work great for porcelain tile but not true to size is about a 1/32 small.

I used these to install grab bars on shower tile. I had bought some carberendum bits locally that couldn’t handle the job. These are the real deal. Just keep spraying water while you drill. Even the best bits burn up under friction.

These are fantastic, the four cutting blades on the head make all the difference. Drilled three holes with one bit, where 2 cheap ones were spent before making it halfway through!

Not actually 1/4” (.3mm smaller), still, with 4 flutes, it functions well and doesn’t walk.

One bit lasted 5 holes. Previous purchase of "diamond tipped" bits were lucky to do 2. Made install of shower doors quick & easy. Key was to mist with water while drilling. You'll be happy you did

Was really looking forward to using this product on my fireplace to hang some decor. Used on brick. Bit heated quickly and broke in hole. Tried another, same thing. Took the set outside and found the same issue. May be good on wood, but definitely not masonry as suggested.
