About This Product
9" Wet Cutting, Grinding, Profiling and Core Drilling System
The Alpha® ECG-900 Wet High-Speed Angle Grinder is a multi-use 9" system for wet cutting, grinding, profiling, and core drilling. The 15A grinder operates at 6,200 RPM and accepts cutting discs up to 9" in diameter, providing up to 3-3/8" cutting depth for demanding stone and masonry applications.
Quad-W Water Delivery for Wet Cutting
The Quad-W Drive distributes incoming water through eight channels along the side of the blade core, delivering water evenly to the cutting edge while minimizing water volume, mist, and splash. A 15 ft. water hose with a quick-connect shut-off valve is included for water supply and control during wet operation.
Adjustable Handles for Cutting and Profiling
A rotating handle allows the grinder position to be adjusted for more comfortable cutting, while the included C-Handle provides additional stability for profiling, core drilling, and grinding. The system can profile material up to 6 cm (2-3/8") thick for applications such as pool coping and cap stone fabrication.
Complete Wet Grinding System with 9" Blade
The ECG-900 includes a 9" MasonMaster blade, blade guard assembly, splash guard, handle components, water hose assembly, GFCI, Memory Wrap, and other operating accessories. For dry applications, the grinder can also be used with a compatible Ecoguard and HEPA vacuum system.
