Key Features
Switchable Soft Percussion
Keeps diamond segments sharp and assists the general efficiency of the dry drilling process.
Robust Oil-Bath Gearbox
The 3-speed oil-bath gearbox allows optimized torque and drilling speeds for a wide range of diameters. The mechanical slip clutch protects the system.
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.
Integrated Convertible Port
Convertible port allows quick change from water feed for wet drilling, to through-the-spindle dust collection for dry drilling. The port can be rotated to any desired position.
Anti-Seize Ring
The motor comes standard with an anti-seize ring which helps prevent the bit becoming stuck on the spindle.
Load Warning System
The LED Load Indicator gives visual information on load conditions, making it easy to operate the motor at its optimal load range.
