Cut granite cobblestone and setts with a segmented or turbo granite blade on a 230mm grinder or wet saw. Granite is hard, so use a medium-hard bond blade, cut wet when possible, and feed steadily — for curved layouts, trim setts with a grinder and finish edges with a chisel for a natural look.
Cobblestone setts are often granite or basalt — dense, hard stones that wear blades quickly. A blade with too soft a bond will wear fast; one too hard will glaze and stop cutting. Granite-specific blades with a medium-hard bond balance speed and life.
The Granite Saw Blade (Long Segment) suits production cutting; the short-segment version is smoother for trim work.
You can, but granite is harder than concrete aggregate and will glaze a concrete blade quickly. Use a granite-rated blade for reasonable life.
Wet is better — it cools the blade, controls dust and speeds the cut. Dry cutting works in short passes with a dry-rated blade and dust protection.
Mark each sett, cut the straight sides with a grinder, then shape the curved edge with small cuts and a chisel. Leave a slightly rustic edge for natural layouts.
Granite cobblestone and setts cut cleanly with a granite-rated blade on a grinder or wet saw. Match the bond to the hard stone, cut wet, and finish curves with chisel work. JOY TECH's granite blades come in grinder and saw sizes for paver and sett installs.
