An asphalt cutter is a tool attachment used for cutting asphalt or similar materials. It can be mounted on various machines and is commonly used in road repair, underground cable and water line work. Most are rotary cutters with hard alloy steel blades and can be used for precise cuts in confined spaces. Walk-behind models are available for small projects. They can also be used for sawing concrete walls and removing debris.
An asphalt cutter is a bit attachment that is mounted on various tools such as hydraulic breakers, loaders, backhoe loaders, tractors and motor graders. As the name suggests, it can be used to cut asphalt or other similar bituminous material, such as concrete. Many utility contractors, road patching crews, and road superintendents use an asphalt cutter, as one can be useful for repairing roads, underground cables, and water and sewer lines. Some professionals prefer asphalt cutters to jackhammers, due to the clean cut it produces and the amount of work it can do.
Most asphalt cutters are rotary cutters. After being mounted on a machine, the attached bit moves forward and, aided by the downward pressure of the machine, cuts the asphalt. Usually, the larger the machine the cutting bit is attached to, the more downward pressure is generated, thus enabling it to cut harder types of material. The asphalt cutter is often used when precise cuts are required, or when working in confined spaces.
Asphalt cutters are commonly made with hard alloy steel blades. Steel can be heat treated to improve its sharpness and durability. The cutting wheel is often relatively thin, as this allows it to make more precise cuts. Some cutters may also have diamond tipped blades. Replacement blades are usually available, as they can become damaged due to the hard materials they have to cut.
Different asphalt cutter models will specify which types of machines are compatible with them. Some are attached to a vehicle, such as a tractor, using heavy-duty clamps. Other types of asphalt cutters can be mounted on a boom device. The cutters differ according to the quality of the blade and its depth of cut. Some models may even be able to cut in or around curves.
There are also walk-behind asphalt cutters, which alleviate the need for another machine to mount the cutter on. These types of machines usually have a sturdy frame to absorb vibrations and the cutting disc can be raised and lowered accordingly. These walk-behind models, however, are typically only used for small projects.
Asphalt cutters are often used not only for making cuts in the ground, but also for sawing concrete walls. This can help with building projects, such as creating or enlarging doors and windows. Cutters were also sometimes used to remove debris, making precise cuts in areas carefully determined in advance by structural engineers.
