Pre-bullnose slate edges for straight termination points such as vertical pieces of steps or countertop edges. Change out the blade on your tile wet saw, and attach a profiling wheel to the saw in place of a normal cutting blade. Run the pieces of tile through the saw with the edge pressed against the profiling wheel to round the edge off and create bullnose edging.
Bullnose the edges of an existing installation with a hand-held tile-cutting tool. Attach an appropriate-sized profiling wheel to the hand-held cutting tool, and run it along the straight edges of your installation to bullnose the edges, such as with an existing countertop, island or other area where you have a straight section of slate tiles that needs to be bullnosed.
Create custom bullnose edging using a bullnose kit for areas such as curved island countertops or tub surrounds where the vertical tiles terminate in a curved area that requires curved cuts that cannot be profiled with a normal profiling wheel. Attach the roughest pad in the kit to the variable-speed machine, and apply pressure to the pad while you adjust the angle against the edge of the tile until you achieve your desired bullnose look.
