The Stone Master WE14-125VS 5-inch angle grinder with electronic speed stabilization is designed for heavy operating conditions such as grinding, cutting and finishing granite, marble or concrete as well as grinding and finishing specialty metals. The VTC electronics enhance productivity by constantly monitoring the RPM of the motor, adding voltage as the load increases, enabling the grinder to maintain the same RPM from no load to full rated load. The grinder also incorporates “CoolFlow” technology with repositioned carbon brushes for unrestricted airflow and a fan that pulls 35% more air through the tool to keep it running cooler during operation. In addition, the grinder features an aluminum die-cast housing to help with heat dissipation and provide increased durability.
The grinder features a robust motor as well as a variable speed range from 2,800 to 10,500 RPM. The motor and other essential components are protected from harmful dust and debris with double-lipped labyrinth sealed bearings, a unique winding protection grid and epoxy coated field coil windings.
Safety features include a tool-less guard adjustment, spindle lock and an “S-Automatic” safety slip clutch to protect the operator from kickback by absorbing the torque created if the wheel binds or snags. The power interruption protection feature prevents restart in the event that power is lost to the tool and the switch remains in the on position, protecting the operator from injury and the work surface from damage when power is restored.
