Brand story
35 years of chainsaws that cut concrete
63cm
Longest guide bar in the 890 series
Could a chainsaw cut concrete the way it cuts wood? ICS answered that question. It was the first in the world to perfect diamond-segment chain technology, creating the concrete chainsaw category itself, and it still sets the standard within the Oregon Tool group today.
A circular blade reaches only about a third of its diameter and leaves overcuts at corners. A chain works differently: it cuts as deep as the guide bar goes, right through a wall, and a corner ends exactly at the corner. For square openings like windows and doorways, that difference is decisive.
The PowerGrit pipe-cutting system is ICS patented technology for water and sewer work. There is no need to work around the pipe — the cut is completed from one position in the trench, reducing excavation and keeping the operator safer. It is used by utilities worldwide.
