Attaching Tile drill bits to angle grinder
- Thread starter branimal
- Start date
If you have a common 5/8-11 thread on your grinder then something like the above will help you adapt a common drill chuck that will hold your 2 styles.
I used the search https://www.google.com/search?q=5/8...512i650l3.28167j0j15&sourceid=chrome&ie=UTF-8
to find the above. If you don't have a 5/8-11 thread the use your thread +chuck to find other options.

no neat sig line
Common 4 or 4-1/2" angle grinder is typically spinning at 10-12k rpm.
Not many drill bits or drill bit applications should spin at 10-12k rpm. Not good for the drill bit or the drilling application, for multiple reasons.
Just what are you attempting to do?

Holes in porcelain tile.... Didn't think bout the limitations on RPM...

Use a drill bit in a drill. 
No need to try and rig some way to spin a drill bit with an angle grinder. Wrong rpm from the tool for the bit and way too much unneeded work trying to rig up something.
Reminder that those diamond drill bits are made to be used WET with water. Spray or drip water on the tile and bit before and during use, or if you are drilling vertically down you can rig up a little dam around the hole location with some putty or even play-dough and put some water inside the mini lake/pond. The water helps cool the bit and the workpiece and also helps keep down the dust.

Got it. Will stick with the drill and a wet sponge. What do you do to make sure the bit doesn't walk?Use a drill bit in a drill.

Do you need a perfectly precise hole? I just drilled five holes in my porcelain tile shower yesterday to install a shower glass door. I used a quality 5/16" masonry bit and my M12 SDS Plus hammer drill. It worked just fine.
The Milwaukee bit linked is fine, I have just used those to install 8 grab bars on porcelain tiles with 3/4 holes diamond bit and 3/16 carbide tip holes for wingIt, no issues with just a cordless drill ez job... just use a spray bottle for some water as coolant. only bad thing about those bits... if you hit stud , wood or steel... the diamond goes bad pretty quick. so.... Don't go monkey it too hard.
They do make diamond bits for granite or porceline hard surfaces that fits onto the grinder that is 5/8-11 threads. but the one you lined is not it.

or you can search for diamond granite bits 5/8-11... those stone guys use them...
like these things just from a quick google foo.

you start the cut and pressure toward one side of the cut then rock it slowly back to straight and center.... if the hole is small like under one inch they sell some of those plastic guides with double side tape for common size hole... or make one your self from pvc.

Looks like a problem in the making; better to use the right tool for the job.

Just like with the grinder you start the drill bit sort of on an angle so you start cutting just one side of the hole then slowly move the drill up to perpendicular with the tile you are drilling. That's the same technique I use with the hole cutters on the angle grinder for the bigger holes. I used to have a cool little container that would hold water and drip it slowly, I could attach it right above a hole when doing vertical stuff and it would drip onto the bit while I went. It wasn't very sturdy and broke pretty fast. Now I usually look to buy bits and hole cutters that can be used dry.
