Being lightweight, they allow for easy transportation. They fit tight spaces, making precise cuts in hard-to-reach areas. Hand-held saws use electric, hydraulic, or gas-powered motors.
For jobs like cutting pipes or creating joints, hand-held saws are ideal. They are often the first choice when quick, straightforward cutting is necessary. However, for deeper or longer cuts, other types of saws may be more suitable.
Walk-Behind Saws
These saws are perfect for large projects. They cut deep into concrete and are a go-to for floor and road work. Walk-behind saws come in different sizes. Some are small and can fit in confined spaces. Others are large, requiring more space to operate.
Walk-behind saws provide straight, deep cuts and are useful for lengthy cutting jobs. Workers push them from behind, hence the name. These saws offer stability and can cut through thick concrete efficiently.
Many walk-behind saws feature depth adjustment controls. This allows for precision when setting the desired depth. They are also less tiring to use on big tasks compared to hand-held saws.
Wire Saws
Wire saws are special tools for complex cutting jobs. They use a metal wire, infused with diamond segments, to cut through concrete. This saw type is excellent for large sections or where there’s a need for very precise cuts.
Wire saws can handle irregular shapes and sizes. They are often the go-to for demolition work. These saws cause minimal disruption and are a safe choice for sensitive cutting environments. Wire saws are also known for their ability to cut through heavily reinforced concrete.
Using a wire saw requires more skill and setup but delivers unparalleled precision. For huge and intricate cutting projects, wire saws are the best option.
Essential Features to Consider Before Buying
When selecting a concrete cutting saw, it’s important to pay attention to certain key features. These features can greatly impact the saw’s performance, and choosing the right ones can ensure you have the right tool for your project. Below, we’ll highlight the critical features you should consider before making your purchase.
Power Source
The power source of a concrete cutting saw determines its mobility and the kind of environments where it can be used. Generally, you have three options:
- Electric: Ideal for indoor use as they don’t emit fumes and are relatively quiet.
