Diamond Segments: Turbo or continuous rim design ensures smooth, vibration-free cuts with minimal chipping on delicate marble surfaces; advanced electroplated bonds dissipate heat for longer life (up to 500–1,000 linear feet).
Versatile Cutting: Ideal for straight or curved cuts in slabs, tiles, countertops, or sculptures; handles marble, travertine, and similar stones without burning or edge damage.
Durable Construction: High-strength alloy core resists warping; suitable for angle grinders, circular saws, or wet tile cutters in professional or home settings.
Safety and Efficiency: Low friction reduces kickback; always use with water suppression for wet cuts to minimize dust and extend blade life.
