LINISHING TILE STONES

THESE ARE USED ON A MACHINE TO SKIM UP TO 5 MM OF FLOOR TILES IN A SUPERMARKET SO THE FLOOR HAS A LEVEL SURFACE.SAVES REPLACING FLOOR TILES MOST TILES HAD CHIPS AND SURFACE MARKS. .I HAVE 12 WHICH WERE IN SKIP.THESE ARE NEW AND I HAVE SET UP LATHE WITH 4 JAW TO HOLD THESE.NOW I USE THESE TO SHARPEN TOOLS .THESE I ONLY USE IF THE TOOL IS BADLY BLUNT.EXAMPLE IF I BUY CHISELS /COLD CHISES ECT!  FROM A CAR BOOT /FLEA MARKET.I GRIND THEM TO HOW I WANT BEFORE I FINISH OFF ON FINE WHEEL ON MY GRINDER. THESE STONES WORK WELL.AND ARE IDEAL TO GRIND A TOOL TO HOW YOU WANT BEFORE FINAL TOUCHES.!! ALSO IDEAL FOR TRUEING UP YOUR WHEEL ON GRINDSTONE.UNLESS YOU HAVE A GADGET OR DIAMOND TO TRUE UP WHEELS.
