I have a bar in my basement that has a "lip" that goes around the top of it.
I don't know exactly what kind of "stone" or "ceramic" that bar is made of but,
I need to "shave" and "widen" the space inside this "lip/bullnose" for about 2-3 feet of the distance of the "lip" in order to insert a square shaped "rope light". :001_unsure:

For about 90% of the distance of this "lip", there is plenty of room for the rope light to be instrted (I am attaching the rope light with 3m VHR double sided tape). As far as how much more I need to "widen" the inside dimension of the "lip", I need to widen it about 1/8" of an inch.

The problem/question is, what type of stone cutting tool will be best to help me achieve my goal? Should I use a "Rotary Stone Grinder" like any of these? :vs_worry:

There is probably only about 8" of space between the counter top and the "lip" so it has to be a relatively slender/hand held tool.

Here are some photos of the bar and the area I need to "widen/shave". Thanks. :smile:

A 4-1/2" right angle grinder with a diamond blade should do it, but there's going to be dust everywhere so you may want to have someone hold the hose on a wet dry vac near where your cutting.

I agree. Small angle grinder with a 1/4" masonry wheel. It will make short work of that groove as well as one hell of a mess

Thanks guys! Will do!
As far as the dust flying every where issue, how about if I cover myself and the entire bar area with a giant transparent/translucent plastic drop cloth that I have (size is 10 ft x 20 ft) and also have the shop vac hose end planted right there taped to the top of the counter for whichever location I am cutting?

Thanks!

Is this considered a "right angle" grinder even though it's title says that it is a "Angle Ginder" and not specifically a "Right angle grinder"?

I think this would be better for what you want to do.

Bear in mind that some of your material (looks like tumbled marble) MAY come loose from the vibration.

Thanks! Nice tool!
Do you think it will cut stone, since it doesn't mention the word "stone", just steel etc. Thanks!

Even if you can make that cut without damaging anything you'll still have that inside corner to deal with (grinder isn't going to do it).

How wide is the existing gap? You can get 1/4" rope light.

Ayuh,.... The material it'll cut or grind, more depends on the wheel ya mount on the tool,.....
The one that comes with it, ain't anywhere near the proper wheel that you need,....
Ya need a diamond rim cuttin' wheel,...

I'd probably go with the 4, 1/2" angle grinder, 'n a thin diamond blade for what yer doin',....

Tentin' the area with yer drop cloth will help, the vacuum nozzle right at the work is more critical,...

Thanks and they do have what they call "tape light" see YouTube link below, but the transformer/driver for Tape Lights are not compatible with my Lutron Grafik Eye dimmer which I want to be able to dim these lights.

w/o a doubt, diamond is FAR more preferable than any other blade type,,, continuous rim or slotted segments - either 1 will work,,, the 'key' is holding the vac nozzle CLOSE to your blade,,, put on some tape, draw your cut lines on the tape, & have at it,,, turn the grinder on & let it spin up BEFORE starting the cut or motor torque could cause a miss'd line,,, you can also use the same 4" blade in the corner,,, 5min & you should be able to get a good 'handle' on it

good luck
