Need Type 27 Depressed Center Diamond Wheel to Cut Ceramic Tile

ejriddell's picture

I hope someone can help me.  I have a Ryobi Angle Grinder which only uses Type 27 depressed center wheels.  I need to find a diamond wheet to cut some ceramic tile.

I have spent at least two hours on line trying to find one.  I cannot find anyone who sells or manufactures this item (even Ryobi).

If anyone has any ideas, I will be truly grateful!  Thank you!

Spindle size?

my Bosch will fit flat diamond discs as well as those set up for grinding (depressed center).  I've not seen any angle grinder that didn't.  Cutting, correct arbor size and that spindle nut kee the cutting disc on.  Some discs thread right on the spindle.

no?

I'm not familiar with any ryobi tools however.  Check the Bosch parts list for smooth (not segmented diamond cutting wheels.

I don't own a Ryobi grinder, but is that a battery-powered grinder?

They might have that restriction in there because they don't want you using a cutoff wheel at low RPM due to a tired battery. At low RPM the wheel could catch an edge and things could go downhill pretty quickly.

I have a Ryobi grinder, model (post #211089, reply #3 of 8)

I have a Ryobi grinder, model AG452.

Ryobi does not have a Type 1 guard available for those grinders ( none that I could find)  so using a diamond or other cutting wheel leaves part of the wheel completely exposed on one side.  Hence the warnings in the manual never to use a Type 1 wheel or else a "serious injury will occur"

My experience ( not a recomendation! )

I have used the cheap continuous rim diamond blade from Home Depot without injury or incident.  Same with the Lancelot  woodcarving blades which turns the grinder into a small circular chain saw.

If you choose to use a Type 1 wheel, be aware of the open side.  If doing deep plunge cutting, have everything set up so you have full control of the cut and will not be binding the blade.

You could take a spare guard and close off the bottom surface to make your  own Type 1 guard, if you think the additional blade coverage is warranted.

Cantmandeux, Mongo and Calvin - You guys are awesome.  Thank you for the quick reply.  The spindle size is 5/8".    Now that I know Ryobi does not make a guard for this type of wheel, I get why the manual said to NEVER use a Type 1 disk.  

I'm new to power tools, so I probably won't risk using the Ryobi without a guard.   I'll buy another grinder (or maybe even a tile saw) to use just for that purpose.

Thanks again!

maybe you can help me this time.  What is a type one guard?

for the 30 yrs or so I've had this Bosch angle grinder with a half , top covered guard that I can position in a half arc .........I've used every cutting disc etc ........

Are  you telling me there's a different guard than I have or does your grinder not have a guard of any kind?

 

thanks

Thank you for educating me.  

No joke, I had no idea and have been cutting and grinding a whole lot of material with the equipped when bought one sided guard.

so, is this a semi recent safety feature or one that's been around ?  I have never considered the option, nor knew it existed.

thank you two for the info.  I'll spread it around to the rest of the risk takers around here.

I see Bosch makes one to fit (post #211089, reply #8 of 8)

I see Bosch makes one to fit my Bosch AG50-11VSPD 5-Inch Variable-Speed Angle Grinder.  I thought a 5 inch grinder might come in handy, but it's hard to find 5 inch discs.   This grinder is the mother of all small angle grinders though.  I like the soft start and variable speed, and crazy power of this grinder.   It will also shut off if a disk suddenly stops turning, but that hasn't happened yet.
