The PM 40-MG is a multiline laser used for laying out interior partitions and service installations. The tool has a green beam, which is four times more visible than traditional red lasers – it is clearly visible from over 25 meters away, even in bright daylight. The tool uses a rechargeable battery which is cross-compatible with all other Hilti 12V tools. Engineered to provide the durability needed on construction sites, the PM 40-MG uses Hilti Metal Blade Axicon technology. This protects all sensitive diodes and prisms from drops and rough handling, ensuring the device maintains accuracy for longer.
