• Best For: Brick saws that take a 20-inch blade on a 1-inch arbor, for acid brick and hard brick.
• Highlight: The 20-inch by .145 size of the MK-410R, the larger and thicker of the two listed sizes.
• Expert Note: Check your saw's maximum blade diameter before choosing 20 inches; the 18-inch MK-410R at .135 width is the alternative for smaller saws.
