cut perfect of the LEMAN metal cutting discs

LEMAN metal cutting discs use an inexpensive angle grinder with a diamond blade to cut perfect circles and squares in even the toughest tile. You can buy a 4-in. or 4-1/2-in. grinder for as little as $50 and a dry-cut diamond blade to fit metal grinding starting at $20. In general, more expensive blades will last longer. When you’re choosing a diamond blade, look for one with a continuous, rather than segmented rim for the smoothest cut.
