What does a concrete cutter do?

A concrete cutting saw is a tool that runs on gasoline, pneumatic pressure, hydraulics or an electric motor. It is also known as a road saw, cone saw or slab saw. A concrete saw is used to cut hard materials such as concrete, tile, asphalt, brick, masonry and other solid materials. So when do you want to start cutting concrete slabs with a saw? When choosing which area to start cutting expansion joints, select an area that does not have any steel reinforcement that continues from one slab to another.

Diamond chainsaws and cutting machines are the two most popular concrete cutting tools used in the construction industry. Hand sawing is a traditional method of cutting concrete, but it takes a lot of time and effort. In addition, the depth of cut is usually not satisfactory. Understanding the capabilities and limitations of concrete cutting machines and diamond chainsaws will help you determine which tool is right for your job.

Cutting machines and diamond chainsaws are the two most common concrete cutting tools, and their uses overlap quite a lot, but they are not interchangeable. By understanding the differences between these two types of teams, you can make the right choice for your next job. The ideal choice for most concrete cutting jobs, cutting machines are hand saws that are used to cut concrete, asphalt and metal. They use a composite resin grinding wheel or diamond blade for cutting in various construction applications.

Typically available in 12- or 14-inch sizes, cutting machines can be operated with a two-stroke gas engine, hydraulic power unit, air compressor or electric motor. The choice of power supply depends on the application. According to Tom Carroll of CS Unitec, power saws are popular with some operators because they are light, less noisy and easier to use than other types of cutting machines. However, they are not as powerful and may take longer to complete a job.

Hydraulic saws, on the other hand, have the highest power-to-weight ratio. They are convenient because most contractors have a hydraulic power unit on hand, but they are more expensive and less tolerant than a pneumatic saw, for example. Air saws are also convenient, as air compressors are ubiquitous on job sites. The operation is simple and has fewer potential risks, says Carroll.

If the blade gets stuck, the air pressure is simply released, he says, adding that there is no risk of fluid leakage either. Air saws are also lightweight and easy to maintain. The most popular among the various types of cutting machines are gas-driven units. These tools offer the advantages of portability and familiarity, but require more maintenance.

In addition to power requirements and maintenance, there is also the question of weight versus performance. Operators appreciate a lighter saw because they are easier to use, but there is a trade-off. It depends on what the operator really wants, says Axt. If the saw is lighter, it will cut shallow with more passes, so it may take longer.

A heavier saw, on the other hand, will cut deeper and faster, but it is heavier, which can make it difficult for some operators to handle. He continues: “For some, time is money.”. Others prefer to save wear and tear on the operator. There are several things that operators should keep in mind when using a cutting machine.

The end user must read, understand and follow the instructions and warnings in the instruction manual, says Steve Parmentier, Strategic Account Manager at Stihl Inc. It points out that end users must also have all appropriate personal protective equipment as described in the instruction manual. A diamond chainsaw is a tool designed as a woodcutting chainsaw with a motorized head, guide bar and chain, which is driven by a sprocket from the powerhead around the guide bar, explains Bill Bray, ICS vice president of sales and marketing, Blount Inc. As the name suggests, the chain of a diamond chainsaw incorporates diamond segments that are laser welded to the chain instead of the typical cutting teeth of a wood saw.

Diamond segments, as in a traditional circular diamond blade, essentially create a grinding action that wears away concrete, brick or other aggregate material. This grinding action creates a very safe cutting operation without the recoil that is associated with a wooden chain. Diamond chainsaws offer several advantages over circular blade cutting machines, says Bray. The chainsaw is designed to dip the tip first into the material and has the ability to cut more than twice as deep as a 14-inch circular blade.

The smaller ICS gas saw allows a 10-inch deep cut and, depending on the saw model, there are gas saws that can cut a total depth of 16 inches, says Bray. A gas saw with a cutting depth of 12 inches is the most common on job sites. There are hydraulic diamond chainsaws that can cut to a depth of 25 inches. A 14-inch circular blade on a cut-off saw is designed for a maximum depth of just under five inches.

When selecting a diamond chainsaw, the most important thing is to consider whether you need to cut openings larger than five inches. If the answer is yes, then a diamond chainsaw is the right tool, says Bray. Most start with a gas-powered two-stroke engine, offering portability and a lower initial investment. ICS recommends a minimum 80cc engine that can use a guide bar that is 12 or 14 inches deep of cut.

If you have significant cutting needs, you may want to consider a hydraulic or pneumatic diamond chainsaw, which has more power and can use guide bars for openings up to 25 inches. Contractors who cut concrete should use engineering controls, such as water or ventilation, to limit worker exposure to silica dust. Respirators should be provided if engineering controls cannot adequately limit exposure. When cutting concrete, wet cutting is recommended to help control dust.

Water retains dust and reduces the amount of airborne dust created by cutting concrete. Another option is a dust collection system. Dust control methods should be used when cutting concrete, not only because it is required by OSHA, but because it keeps workers safe and healthy. When choosing the right saw for your concrete cutting job, be sure to also install dust control systems.

Cutting concrete is a daily necessity in construction projects, it is the process of controlled sawing, drilling and removing broken concrete for remodeling and construction. However, before you start working with the concrete cutting saw, it is a good idea to make small test cuts to check if it frays. There are many (if not all) occasions when the work of cutting concrete is above the capacity of a do-it-yourself homemade handyman. Diamond Discs Often, the concrete cutter will use a saw that has a diamond blade to cut the concrete and any reinforcement inside the concrete.

When you hire a professional concrete cutter for your next project, be sure to verify that it meets all necessary safety and environmental regulations, use only the best cutting equipment, and equip your staff with an appropriate range of safety equipment and equipment. It is important to ensure that your concrete cutter has the on-site capability and machinery to perform a variety of concrete cutting methods, as the right cutting solution for the job may not be entirely clear until the concrete cutter is on site. If you need a clean cut, a professional concrete cutter is the only way to ensure the quality of work. Broken concrete must be moved away from the site, either to a yard as a backfill or disposed of in a landfill.

Your concrete cutter must be accredited to this standard to ensure that it has been accredited to carry out its work safely. Issued by the International Organization for Standardization (ISO), this ensures that the concrete cutting service provided consistently meets the requirements of customers and is also constantly improved. When cutting with a concrete saw, try to cut to a depth of a quarter or even a third of the thickness of the concrete slab. Cutting concrete is a specialized skill and to perform quality work reliably and safely can only be achieved when certain criteria described above are met.

Before you start cutting the concrete slab with a saw, you must first select where these cuts will be made in the concrete. Core drilling is mainly used to make wiring path, plumbing, anchor bolts and electrical cables into concrete. An alternate and thin cut is strongly recommended to let air flow around the handheld concrete saw blades to reduce the overflow. Cost of Concrete Cutting The cost of having a concrete cutting service, go out and cut the wall or slab you need is not as expensive as you might think.
