18-Inch Diamond Concrete Saw Blades

Porcelain tile requires a continuous rim or turbo-style diamond blade with a fine, dense diamond matrix designed for smooth, chip-free cuts. These blades are typically run wet to reduce heat and dust. Segmented concrete blades are not recommended for porcelain since they leave rougher, chipped edges.

Segmented blades feature gaps between segments for aggressive cutting and better cooling, ideal for concrete, asphalt, and masonry. Turbo blades have a continuous wavy rim that offers faster, smoother cuts with less chipping, making them suitable for both concrete and harder materials like stone.

Yes, many 18-inch diamond blades with laser-welded segments and undercut protection are designed to cut through reinforced concrete containing rebar. Look for blades specifically rated for concrete and rebar cutting to ensure segment durability and consistent performance during demolition work.

Most 18-inch diamond blades come with a 1-inch arbor with a 20mm bushing to fit a range of walk-behind and handheld concrete saws. Always confirm your saw's specific arbor requirement before ordering, since mismatched arbors can prevent proper blade mounting.

Replace a diamond blade when segments wear down close to the core, when cutting speed noticeably slows, or when segments show cracking or uneven wear. Undercut protection features help extend usable life by protecting the core as segments wear, but eventual replacement is still necessary.

Wet cutting reduces dust, cools the blade, and extends blade life, making it preferable for extended cutting sessions on concrete and asphalt. Dry cutting is more convenient for quick cuts or when water access is limited, and many 18-inch blades are rated for both methods.
