The drill is very robust, steel core, quality plastic, aluminum gear housing. Therefore, it is quite heavy with the battery.
The screwing torque adjustment is done using a first ring (just after the chuck), the drilling mode with or without percussion done using a second ring located after the torque ring .
A button on the top of the drill to select the speed: for screwing 1 and 2 for drilling.
The dinversion button the direction of rotation is positioned just above the switch trigger.
A button on the battery back can test the state of charge, 3 LED.
An LED on the base of the drill (above the battery) lights up during use, not very helpful to me (or I do not know the usefulness of this LED!)
Chuck Ø13mm.
Use:
Drilling in wood (with wick flat Ø35 mm), perfect power, realization of a hundred Ø35 mm holes holding the battery is full.
Drilling in concrete: not beyond Ø6 mm, perfect for drilling in masonry like concrete block, brick. Ok for small bore in the concrete.
Wood screw: good power, wood screws screw Ø6 mm length 200mm test: no difficulty, power is constant, even late in the battery level (1 LED). Shooting-bottom screwing Ø10x150 mm (with front hole): perfect, no complaints.
Great stuff, I love it!
