Is Slate Easy to Cut

To cut slate, you need a diamond-tipped cutting wheel for your grinder. Because slate is layered, it’s difficult to draw an accurate straight line on it. This task becomes easier, and you’ll make a more accurate cut with fewer edge chips, if you first lay masking tape and then score the line into the tape with a knife.

Is slate difficult to cut?

The way that slate is formed, however, makes it nearly impossible to use anything except a tile saw — either a wet saw or a dry angle grinder with a tile-cutting blade. Nippers and score-and-snap cutters will either crush the slate or cause it to fracture along one of its layers or clefts.

How do you break slate into smaller pieces?

Hold the grinder in both hands, turn it on, and score the back of the piece roughly 1/8 inch into the stone on the back side. Hold the piece firmly in your hands and snap the waste edge of the piece against the ground, forcing the tile to break along the scored line. This will give you a ragged cut.
