GX120 nail gun
TE500 AVR breaker

The new GX 120 Gas powered nail gun has been introduced to increase productivity as it can drive 1200 nails an hour into any base material. It does not require a battery, and has a power gauge to indicate remaining gas levels.

An addition to the company's 'breaker' range of products, the TE 500 AVR combines safety with usability.

Featuring a 1600w motor, the compact DD120 drill has a 2-speed gearing system for optimum speed and torque, with the capability to drill diameters between 16 to 162mm.

With forward and reverse functionality, the 650w tool is suitable for 4 to 22mm diameter drilling.

Suitable for installation work across a range of surfaces, it incorporates 2-speed gearing to provide an optimum drilling speed at all times.
