Times have changed. The latest generation of electric cutters from Hilti, such as the DCH 300-X, benefit from wet cutting capabilities and newly customised blades. These two advances accelerate cutting speed by around 30% each, so you can now rely on electric saws for everyday tasks without sacrificing speed.

When you add the additional advantages of electric saws – especially being fume-free and much quieter, so you can use them indoors or in inhabited buildings – it is easy to see why they are the tool of choice for many common applications.

Our largest handheld electric cutters can cut through 120 mm with a 305 mm blade. That’s the cutting depth you normally only get with more expensive 350 mm blades. Thanks to this clever tool engineering, you can cut all the way through a typical concrete or masonry wall or floor from one side – no more having to align and cut from both sides. Routine cutting or widening openings just got twice as fast as with an angle grinder.

Advantages over angle grinders and gas saws

Push, don't pull

Unlike our gas saws and angle grinders, our electric cutters spin their blades in the opposite direction. In practice, this means that you push an electric cutter on its wheels, away from you. This makes it easier to control, so you can get a perfectly perpendicular cut exactly where you need it. Safety improves too, as the blade moves away from the user and is always concealed behind the dust hood.

No throttle

To start an electric cutter, all you need to do is plug it in and pull the trigger.

No double work

Even 230 mm angle grinders will achieve a cutting depth of just 68 mm at best. This limited reach means that you will always have to cut from both sides to get all the way through a wall or floor. By opting for a larger cutter, you get cutting depth that can exceed the thickness of typical concrete or masonry walls and floors, so you can cut all the way through from one side. Put simply, deeper cuts translate to higher productivity.

No fumes

An electric saw has no combustion motor, so is much quieter, more environmentally friendly and can be used indoors.

Wet concrete cutting: more speed, less dust

Wet cutting is fast. Very fast. Water helps to cool diamond blades to their most productive temperature, while also washing away the dust which would clog the cutting surface. Our side-by-side comparisons of wet versus dry cutting have shown that you can cut through concrete around 30% faster when you opt for wet cutting. The DCH 300-X includes a hose connector and dust hood with depth gauge straight out of the box, not as optional add-ons, so you can get to work straight away! Wet cutting has emerged as one of the most effective methods of suppressing dust emissions. All you need is a pail of water and a standard hose attachment.

Customised Equidist blades: Faster and thinner than ever

The latest tweaks to our highest-performance blades mean that you can expect to cut 30% faster than before. Combined with the speed gains from wet cutting, the DCH 300-X offers enough performance to take over many common cutting jobs from gas cut-off saws. The Equidist Super Performance Xtra (SPX) blade is our top-of-the line cutting disc. Built to cut everything, including rebar, SPX represents the gold standard in speed and longevity.

Diamond blades — Need more cutting depth? Or cut a lot of rebar?

Need more cutting depth? Or cut a lot of rebar?

The DCH 300-X’s cutting depth of 120 mm is ideal for cutting or widening openings in all the most common concrete and masonry thicknesses, but we produce diamond sawing tools for very large and specialised applications too. With the DSH 900-X gas saw, you can cut up to 150 mm deep.
