Aligning, plumbing, squaring and levelling made easy with the Hilti PM 40-MG

It might put a smile on your face to see the sun shining but this can be a nightmare when trying to work with traditional lasers - the bright sunlight makes it nearly impossible to see the line.

With the new PM 40-MG, you can keep the smile on your face, thanks to its extremely high accuracy, quick battery charging and outstanding line visibility - even in sunny conditions!

This versatile all-in-one laser, with its four vertical lines at perfect 90° angles and a 360° horizontal line, is all you need for your interior applications.

With a range of up to 20 metres, it's ideal for levelling suspended ceilings, setting out drywall track, transferring reference heights and aligning pipes, as well as doors and windows.

Why does a green beam laser give you more visibility?

Outstanding visibility

The latest green beam laser technology delivers a difference you'll see instantly. We know that all lasers look amazingly bright in a dark room, but in strong sunlight or under powerful electric light, only the very best perform well.

The brilliant green laser beam of the PM 40-MG Multi-line laser is four times more visible to the human eye, sharper and finer than conventional red laser types and delivers significantly better results with greater convenience when working over long distances or in bright environments.

High precision

A rotating platform makes fine adjustment of the vertical line around the plumb point easier, more accurate and quicker for alignment over long distances. 

The sturdy tripod keeps the PM 40-MG Multi-line laser steady under real jobsite conditions such as on uneven and dusty floors, even where there are bumps and holes. Thanks to its adjustable, rubber-covered feet, the tripod compensates for rough surfaces or other obstacles and helps avoid damaging sensitive surfaces.

Long lasting 12v battery

The new PM 40-MG Multi-line laser uses the same batteries as our other cordless 12 volt platform tools. This means you can travel light across the jobsite with just a couple of batteries to fit your 12 volt cordless tools. 

Featuring high-density cells and a smart monitoring system that protects the battery from overheating, our new B 12/2.6 battery delivers optimal performance and a fast charging time of just 25 minutes. One full battery will give you up to 7 hours work, even when using all 4 laser links! 

What's more, if you have 22 volt Hilti tools you can use an adapter to power up your 12 volt batteries using the same charger.
