Key Features
Switchable Soft Percussion
Keeps diamond segments sharp and assists the general efficiency of the 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.
Constant Speed Motor with Aluminum Housing
The 2500 W motor with constant speed electronics make drilling faster, smoother and more efficient, while extending the life of the core bits. The aluminum housing ensures optimal durability and cooling.
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.
Dust and Water-Resistant Switch
The solid-state switch is more durable, reliable, and ingress-resistant than traditional switches. It includes anti-restart function.
Smart Electronic Control system
The Smart Electronic Control system also includes soft-start, thermal protection, and overload protection.
Highly Visible LED Load Indicator
LED load indicator is large, bright, and in the most visible position, to give the operator reliable guidance on load conditions, making it easy to operate the motor at its optimal load range.
Spirit Levels
Horizontal and vertical spirit levels are built into the motor for more convenient set-up.
