Hello there are 2 things you can do.

A) avoid cutting by measuring and arranging them to fit your project. You could go behind the cabinets to avoid cutting.

B) you could use metal borders trims.

Stainless steel tile is challenging to cut. Cuts must be made with a wet saw and a new diamond rimmed blade designed to cut the tile. Tile should be cut face up. Miter cuts are not recommended. Care should be taken cut steel tile can have very sharp edges and burrs. These can be smoothed and dulled with a diamond hand pad, tile blade dressing stone or belt sander using silicone carbide belt.
Drilling holes through stainless steel and cutting can be accomplished with a diamond tipped core bit using a drill with low speed (250 to 300 rpm). Continually missing the tile and drill bit during cutting is necessary. Maintain only moderate pressure during this process. Allow the diamond bit to do the cutting. Again, this helps to keep friction heat low. If partitions or fixtures are to be attached with anchoring bolts, drill hole 1/8” larger to avoid stress transfer to the tile.
