Features & Applications

  • Water kit allows wet cutting, which is 30% faster than dry cutting and virtually dust-free
  • Depth gauge – allows full control of the cutting depth in 10 mm steps from 40-120 mm
  • Ensures a virtually dust-free jobsite when used with a compatible vacuum cleaner
  • Protection against overheating, overloading and water – prolongs the tool's lifetime and increases the operator's safety when wet cutting
  • The inverted blade rotation guides the tool away from the operator's body and therefore makes cutting easier and safer
  • Cutting reinforced concrete, granite kerbstones, slabs, brick and masonry blocks
  • Cutting and extending openings for windows, doors and shafts
  • Making preliminary cuts for controlled demolition

DCH 300-X Electric Cutter

How to cut through walls in half the time

DCH 300-X Electric Cuutter

The power of a full-size saw with cutting depth and precision far beyond 9" grinders: learn how electric saws can improve you

Let’s cut to the chase: electric cutters have always been the saw of choice when low maintenance and precision take priority. What they lacked, however, was raw power.

Times have changed. The latest generation of electric cutters from Hilti, such as the DCH 300-X, benefit from wet cutting capabilities and newly customized 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. Only the most demanding, specialized applications will need the extra power and cutting depth of a larger saw.  

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. Hilti’s largest handheld electric cutters cut through 120 mm with a 12” blade. That’s the cutting depth you normally only get with more expensive 14” 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.  

Today’s electric concrete cutters have four major advantages over angle grinders and gas saws:

Push, don’t pull  Hilti's electric cutters spin their blades in the opposite direction to most others, including gas saws and angle grinders. In practice this means that you push an electric cutter on its wheels, away from you. This makes fine control much easier, 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 double work – even 9” angle grinders will achieve a cutting depth of just 60 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 throttle – to start an electric cutter, all you need to do is plug it in and pull the trigger.     

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 profit from this much faster way of working immediately.

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. Silica dust levels can be kept within OSHA Table 1-compliant levels simply by connecting an approved vacuum while dry cutting.

Customized Equidist blades: much 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. 


Need more cutting depth? 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 Hilti has diamond sawing tools for very large and specialized applications too. With the DSH 900-X gas saw, you can cut up to 150 mm deep. Still not enough? With the DS TS20-E electric wall saw you can cut up to 710 mm deep.

When it comes to cutting rebar, Hilti’s Equidist diamond blades are the obvious choice. These blades are subject to an extremely precise manufacturing process, where each diamond is arranged individually into a grid on the cutting surface. Equidist technology means that blades cut faster, last longer and speed through more materials. Thanks to the combined effect of all these innovations, you can expect to reduce your cutting time by up to 30%.
