Review on Diamond Coated Lapidary Needle Jewelry by Tom Goodlow

IS MUCH BETTER THAN I THOUGHT BUT HEY I THOUGHT I SHOULD TRY SOMETHING BETTER THAN I HAD TO HAVE TO DRILL SOME TALL OPALS. I BUILT A WATER BATH AND TRY IT,,,,,,THE BITS ARE AMAZING,,,,,,AGAIN WORK SLOWLY AND LET THE TOOL DO THE WORK AND BAM,,,,PERFECT HOLES EVERY TIME,,,, , , I AM STILL A LITTLE SHARP AFTER DRILLING 5 AGATE PENDANTS AND GETTING STRONG,,,,,,I HAVE ORDERED MORE AND RECOMMEND TO ALL,,,,,,,,,DON'T FORGET THE WATER!
