There are many different approaches to cutting and removing concrete. Ring saws are one option because they are easy to handle, but they also have many limitations. If you need thicker materials cut and want something done with precision, a diamond wire saw is a better option.

Diamond wire saws are used to remove reinforced or large concrete structures by segmenting. Wire saws can cut through nearly any material because diamonds are among the hardest materials in the world.
In short, a diamond wire saw is a saw which rotates loops of wire cable onto which are threaded metal beads crusted with diamond chips. The entirety of the cable and the beads is then protected from corrosion by an elastomeric compound covering. The cable is made of multiple strands of high-tensile steel wire.
How Do Diamond Wire Saws Work?
If you&#;ve ever used a bandsaw or reciprocating saw, a wire saw operates using the same basic principles. The diamond wire is arranged around the material that requires cutting. It can also be threaded through a core hole. Then, the wire saw is rotated at speed, using the abrasion of the diamonds on the wires to cut through the concrete or other materials.
Diamond wire cutting produces a significant amount of heat, which means cooling is essential. Many diamond wire saws use &#;wet cutting,&#; meaning there is a flow of water to provide cooling.
What Are the Benefits of Using Diamond Wire Saws?
Using the strength of diamonds to cut through thick, dense, and hard materials like concrete and metal is incredibly useful. Here are some of the main benefits of diamond wire saws.
They Can Cut Any Size
Diamond wire saws have the ability to cut through any thickness or size of concrete and steel. The power and precision of these tools mean that they can tackle major projects like columns, beams, sections of bridges, dams, and other structures. Once cut, the sides of the material are smooth, making them easier and safer for workers to handle.
They Are Incredibly Accurate
Diamond wire sawing is incredibly accurate. Trained professionals can deliver precise results even in the most extreme conditions, such as underwater or in tight spaces. Diamond wire saws are also very effective at cutting awkward corners and odd shapes. The flexibility of the wire allows technicians to complete work to precise specifications.
They Are Highly Efficient
Time is money when it comes to construction and demolition projects. Diamond wire cutting does the job with incredible accuracy and speed. Other cutting techniques don&#;t come close to measuring up. Because it is so efficient, there are less wasted materials at the end of the process and fewer work hours required to get the job done correctly.
They Are a Safe Option
Removing concrete and steel isn&#;t a safe activity by any means, but using diamond wire sawing is one of the safest options for workers. It&#;s fumeless, less vibrational, and quieter than other sawing options. With that said, only trained professionals should use diamond wire saws.
What Are the Different Applications for Diamond Wire Saws?
Diamond wire saws were initially used to cut stones in quarries. Over the years, their uses have expanded substantially. A diamond wire saw can cut through concrete (including reinforced concrete), steel, stone, granite, and brick. Some of the most common applications for wire sawing include the following.
Precision concrete demolition projects
Cutting through concrete structures, such as dams, bridges, columns, beams, and factory floors
Dismantling
nuclear power plants
Cutting through openings with limited access
Angular cuts on horizontal and vertical structures
Precision cuts on restricted, sensitive, or confined areas
Cutting through heavy rebar or embedded steel
Subsea cutting of, pipelines, and other underwater concrete or metal structures

Concrete wire sawing gives the most precise cuts on ridges, beams and piers when it comes to making openings in thick walls or removing large concrete structures. Concrete wire sawing can also be referred to as diamond wire cutting. Fine Cut&#;s operators are able to cut through steel and heavily reinforced concrete.
Wire sawing is an innovative method of cutting mass concrete structures and has opened up endless opportunities for the construction industry. Originating from an ancient technology used in stone quarries, modern concrete wire sawing of reinforced concrete came to the forefront in the early &#;s.
The diamond wire of the wire saw consists of an inner cable usually about a quarter of an inch in diameter. Fitted on this cable are beads with diamond grit , which are the cutting or chipping tools of the technology that have springs in between them to provide flexibility of the wire and projection of the inner cable. Some wires are coated with vulcanized rubber to provide protection for the spring and the inner cable. It also helps prevent the diamond beads from bunching or flying off the cable if it were jammed.
The diamond cable is threaded through core holes, providing access for the wire to go through the concrete structure and the direction of the cutting plane. The ends of the diamond wire are hydraulically pressed together utilizing a joint press, creating a continuous loop. To begin cutting, the diamond wire saw then tensions the wire and the wire is spun at about 60 miles per hour. The tension and rotation of the wire create a tremendous cutting force, enabling the wire to cut easily through the structure. This diamond wire can also be placed around the outer perimeter of an object where no core holes are required.

Fine Cut Concrete Drilling and Sawing, LLC first launched as a one truck operation in March . Jim Ralston &#;s vision began after he mentored with and worked alongside some of the biggest names known in concrete cutting. He set out to make a dream come true with only a handful of customers. Fine Cut established a foundation based on loyalty and integrity. That foundation grew into a reputable company that now serves the entire Kansas City metro area, surrounding cities and local communities. A dedicated work ethic and determination drove the business toward its continued success.
In , Clay Kohler expanded on Fine Cut &#;s potential by aggressively remodeling the company&#;s vision and long-term goals. With Jim&#;s knowledge of concrete drilling and sawing and Clay&#;s understanding of managing a business the two joined efforts in making Fine Cut Concrete Drilling and Sawing, LLC a viable company for contractors and homeowners to rely on.
