Key Features
3500 W Universal Motor with Aluminum Housing
The high-efficiency motor features complete electronic protection, including overload and thermal protection, as well as soft start. It also features Slow Start: which automatically runs the motor slowly for a short time, which assists in starting the kerf.
Robust Oil-Bath Gearbox
The 4-speed oil-bath gearbox allows optimized torque and drilling speeds for an extremely wide range of diameters. The mechanical slip clutch protects the system.
Intuitive Load Warning Systems
The LED Load Indicator gives visual information, and the overload protection system shuts the motor down if it is overloaded for too long. Together these make it intuitive and easy to operate the motor at its optimal load range for maximum work efficiency.
Anti-Seize Ring
The motor comes standard with an anti-seize ring which helps prevent the bit becoming stuck on the spindle.
Spirit Levels
Horizontal and vertical spirit levels are built into the motor for more convenient set-up.
Dust and Water-Resistant Switch
The solid-state switch is more durable, reliable, and ingress-resistant than traditional switches. It includes anti-restart function.
