Saws
Hydraulic cut-off saws cut concrete, asphalt, and steel with the reach of a handheld tool and none of a gas saw’s exhaust. The Atlas Copco LS-14, APT MHS14, and CP SAW 14 all use a direct-drive layout in place of a belt, which cuts maintenance, and an open cutting face that lets the blade work flush to a wall or into a corner. A water kit is available on each to supply cooling water, and a lightweight cart turns one into a floor and road saw for light surface work. All three run off a hydraulic power pack. Also in this group: core drills and augers. Free UPS Ground shipping on every saw.

Direct Drive and an Open Cutting Face
Two design points drive the choice. Direct drive removes the belt, the tensioner, and the guard clearance a belt needs, so there is less to maintain and less to fail mid-shift than on a belt-driven saw. The open cutting face means the blade is exposed on one side, so the saw reaches flush into corners and along walls where a fully guarded machine stops short. See the APT line for the U.S.-built version.
Concrete, Asphalt, and Steel
With the right blade, one saw covers all three: slab and wall cuts in concrete, pavement cuts in asphalt, and structural steel, pipe, and rebar. That makes a cut-off saw the companion tool to a breaker on demolition and digging work — score the line, then break to it. Where the section is too big to cut, concrete and rock splitters take over.
Water Kits and Dust
Every saw here can take a water kit to feed cooling water to the blade. Water extends blade life on masonry and concrete, and it knocks down the respirable dust that dry cutting throws, which matters wherever silica exposure is controlled. Plan the water supply and the runoff before the cut, especially indoors.
Powering the Saw
These are hydraulic saws, so the drive sits behind the tool. Match the saw’s rated flow and pressure to a portable power pack, then check the hose pair and couplings. Keep spare hose, oil and lube on hand, because a saw that starves for flow simply cuts slowly and cooks its blade.
Common Questions
What is a hydraulic cut-off saw? A handheld circular saw driven by hydraulic oil from a power pack instead of a gasoline engine or a cord. It gives engine-class power with no exhaust at the tool, which is why it is used indoors, in tunnels, and in confined spaces.
Will it cut steel as well as concrete? Yes, with the right blade. All three saws are rated for concrete, asphalt, and steel — see Atlas Copco and Chicago Pneumatic for the full tool specs on each model.
Do I need a power pack to run one? Yes. There is no self-contained version here; the saw is one half of a hydraulic system. If you already run a hydraulic breaker, the same pack will usually feed the saw — confirm the flow rating first.
