Cutting and milling

Rock chain saw

A chain saw carried at the end of the arm, flat bar engaged in a block of rock, clean vertical line of cut, cutting dust; rock face in the background.
The bar goes in over its whole length:
the depth no longer depends on a radius.
Synthetic image.

A chain fitted with cutting elements turns around a flat bar.
It plunges into the material instead of going round it:
the depth no longer depends on the radius of a disc.

Other names for this tool: hydraulic chain saw, stone saw, bar saw, rock cutting chain.

01 Use

What it is for

On the left, the chainsaw bar stops cleanly at the bottom of the corner. On the right, the disc runs past the corner and cuts into the wall being kept. Computer-generated image.

What sets it apart:
the depth no longer depends on the radius of a disc.
Computer-generated image.

The bar goes into the material over its whole length, which allows a deep cut and a corner cut that does not overrun.
That is the practical difference from a disc:
a disc that cuts to the bottom of a corner has already overcut elsewhere, and the overcut shows on the structure that is kept.

The uses are extracting blocks in soft rock, opening a slot in a mass, cutting round a reservation, taking down an element you want to recover whole.
You cut to separate cleanly, not to bring down volume.

A saw cuts, it does not break: on a volume of rock to be brought down, it will always be slower and more expensive than a breaker.
It is justified when the cut has to be clean, when vibration is banned, or when what remains around must stay intact. Compare with the breaker.

02 What we check with you

On which machine?

A rock chain saw fits all couplers, via a mounting plate.
The excavator class, depending on the bar length, and the exact interface: we calculate them with you for your machine.

What the tool does

It is used for cutting rock.
The cutting width and depth, and the tool weight: we calculate them with you for your machine.

What is needed on the hydraulic side

It needs a hydraulic circuit with continuous function.
The flow and the maximum pressure: we calculate them with you for your machine.

Your study sets the exact value for your machine.

A photo of the machine is enough to start.

03 Your study

Have your machine checked.

Describe what you are cutting, the depth needed and what must stay intact around it.
Tell us whether you can water, and whether the site is occupied.

What we need to answer you
  • Your machine Its make and its tonnage.
  • The auxiliary circuit Its flow in l/min, its pressure in bar, single- or double-acting.
  • The coupler in place Its system and its class.
  • The work The use, and the material.

Without these details, the study still begins: we will ask you for them.

04 Choice

What determines the choice

  • 01 — The cutting depth aimed at It is what governs the length of the bar, and it is the main argument for this family.
  • 02 — The material and the cutting elements Soft rock, limestone, concrete, reinforced concrete:
    the chain is not the same, and the presence of steel remains the point that changes everything.
  • 03 — The watering Wet cutting cools the chain, lengthens its life and damps down the dust.
    On the other hand it requires a water supply and produces slurry to be dealt with.
  • 04 — The flow available, continuously The chain must keep its speed in the pass.
    A flow that is only just enough makes it slow down on contact, it rubs, and it wears without advancing.
05 Check

What is checked before ordering

  • The presence of steel in the cut It is known beforehand, from a drawing or a trial hole.
  • The water, where it comes from and what becomes of the slurry On a road and on an occupied site, discharge is not free:
    that is prepared for.
  • The noise and the neighbourhood A long cut on an inhabited site is a real and prolonged nuisance.
    We publish no threshold:
    the hours and the duration are settled with the client.
  • The tension and maintenance of the chain It is a consumable, and its maintenance governs the cut as much as the tool does.
