About This Product
9" Wet Angle Grinder for Multiple Applications
The Alpha® ECG-900 is a 110V, 15A corded angle grinder for wet cutting, grinding, profiling, and core drilling with compatible tooling. Its 5/8"-11 spindle operates at 6,200 RPM and accepts cutting discs up to 9", providing a maximum cutting depth of 3-3/8" for demanding stone and hardscape 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. The system includes a 15 ft. water hose and quick-connect shut-off valve for convenient supply and control.
Adjustable Handles for Grinding and Profiling
The rotating main handle changes the working position of this handheld angle grinder for more comfortable cutting. An included C-Handle, shockproof side handle, and extension bracket provide additional stability during grinding, profiling, and core drilling. With an appropriate profiling tool, the ECG-900 can profile material up to 6 cm (2-3/8") thick.
Complete Wet Stone Grinder Setup
The ECG-900 includes a 9" MasonMaster blade, blade guard, Quad-W5 adapter, splash guard, adjustable handle components, GFCI, water hose assembly, quick-connect valve, and Memory Wrap for cord and hose organization. For dry cutting or grinding, the tool can be paired with an appropriate Ecoguard and HEPA vacuum system.
