The Diamax SEW40050 4″ Cyclone Straight Edge Polishing Wheel is a professional-grade polishing tool engineered specifically for straight-edge finishing on natural and engineered stone surfaces, including granite, marble, quartz, and engineered stone countertops. Part of the Diamax Cyclone Straight Edge series, this wheel is designed to deliver smooth, consistent, and high-quality edge finishes when used on automatic edge polishing machines and backsplash finishing equipment.

Constructed with premium resin-bond diamond abrasives, the SEW40050 combines durability, precision, and efficient material removal. It is engineered to produce even, defect-free edges, removing minor scratches, saw marks, and surface irregularities while preparing the stone for high-gloss finishing or subsequent polishing stages.

The 4″ diameter provides optimal coverage and control, allowing operators to polish both large straight edges and smaller detail sections with consistent results. Its precision-balanced design ensures smooth operation at machine speeds, minimizing vibration and enhancing operator safety during prolonged use.

Designed for wet polishing applications, the SEW40050 reduces heat buildup, extends abrasive life, and provides superior polishing performance, maintaining a uniform finish along the entire edge. It is ideal for professional stone fabricators, countertop manufacturers, and installers seeking a reliable, high-performance tool to achieve professional-grade straight-edge and backsplash finishes efficiently and consistently.
