How Do Diamond Blades Work?

SCIENCE! and Technology Articles on Desert Diamond Industries' BlogSo you have a diamond blade, it cuts stuff, and it cuts it well. That’s good enough for most people. Are you one of those rare and troublesome folk, though, who’s wondered how it works? If you are, then this article was written for you.

We’ve tackled this topic before, but we want to focus on it a bit more today. First, let’s talk about how most diamond blades work.

How Most Diamond Blades Work: Most diamond blades have cutting segments that are made up of diamond grit suspended in some kind of metal matrix or “bond”. Some of these diamonds are on the surface, but most are buried within the cutting segment’s bond.

It’s important to remember two things about these surface diamonds. First, they grind instead of cut, an important distinction that we’ll get back to in a moment. Second, they do all the cutting work on your blade. All the bond does is hold these surface diamonds in place, while the diamonds buried within the bond do, well, nothing.

Now, diamonds are one of the hardest substances on Earth (they lost the top spot in 2009 to two other materials), but even they’ll wear down and stop cutting on a diamond blade.

This is where the bond comes into play. Ideally, the bond will wear away just fast enough to shed worn surface diamonds and expose fresh, sharp diamonds buried deeper in the cutting segment. This means that you shouldn’t notice any change in your cutting speed as your blade wears down.

Problems with Most Diamond Blades: Of course, nothing happens “ideally”. Your blade bond won’t exactly match the materials that you cut. It will either be too soft or too hard.

If your bond is too soft, your blade will wear down faster than normal. This means that you’ll have to replace your blade more often, which in turn means that you’ll spend more than you should on replacement diamond blades.

If your bond is too hard, on the other hand, the surface diamonds – the diamonds that do all of your blade’s cutting – will wear down faster than the bond. This can lead to your blade “glazing over”, where the surface diamonds wear down completely before they can be shed. When this happens, your blade will cut slower and then refuse to cut.

Worn and glazed blades are both dangerous, and for similar reasons.

Soft-bonded blades can have their cutting segments “undercut” in abrasive materials, like asphalt, green concrete, and sandstone, especially if they don’t have undercut protection. Glazed blades, on the other hand, hammer the material instead of cutting it, which increases friction and overheats the welds holding the cutting segments. Undercutting and overheating can both break cutting segments off the blade, injuring or even killing the saw operator.

To avoid broken segments, you should, as a rule of thumb, choose harder bonds when cutting softer materials and softer bonds when cutting harder materials. This isn’t a perfect rule, though, and could force you to change blades whenever you change the material that you’re cutting.

Advantages of Vacuum-Brazed Blades: Vacuum-brazed blades like the Ductile Iron Safety Blade and Fire Rescue Safety Blade avoid these problems because they have their diamonds vacuum-brazed onto the surfaces of their cutting segments. None of the diamonds are buried inside a bond. Instead, they’re all on the surface, ready to cut.

This means that you don’t have to match up the bond of a vacuum-brazed blade to the hardness of your material. Vacuum-brazed blades cut almost everything, including metals, asphalt, stone, and concrete, and are more versatile than other diamond blades.

FOR IMMEDIATE RELEASE

LAS VEGAS, NV, Aug. 22, 2013 – Desert Diamond Industries, the largest supplier of diamond blades to water departments in North America, will exhibit their diamond blades at the Tri-State Seminar On-The-River, to be held by the Arizona Water Association, California Water Environment Association and Nevada Water Environment Association in Las Vegas, NV. They will be at Booth 1222 in the South Point Hotel Casino and Spa from Sept. 24 to Sept. 26 (download a convention program and map in PDF format).

Desert Diamond Industries will exhibit their full line of Safety Blades, including the Ductile Iron Ring Saw Safety Blade and the Ductile Iron Safety Blade, as well as a wide range of concrete and asphalt blades, Husqvarna cut-off saws and ICS chain saws.

Nicholas Mione, owner of Desert Diamond Industries, said that the Tri-State Seminar would give his company a chance to meet face-to-face with its West Coast customers. He added that many of these water companies didn’t attend the ACE13 conference in Denver, CO, the last water industry convention that Desert Diamond Industries attended.

“It’s going to give us an opportunity to network and meet with our West Coast clients and promote the latest innovations to the water industry,” Mione said.

Founded in Las Vegas, NV in 2008 by Nicholas Mione and Gionni Mione, Desert Diamond Industries is now the largest supplier of diamond blades to governmental agencies in the United States and Canada. Up to 90 percent of water and underground utilities, fire departments and foundries in these two countries use Desert Diamond Industries’ signature Ductile Iron Safety Blade and Fire Rescue Safety Blade.

Gionni Mione, President of Desert Diamond Industries – “Our Plans Are Growing”

Gionni Mione, President of Desert Diamond Industries

Gionni Mione, President of Desert Diamond Industries

Gionni Mione, 24, is president and part-owner of Desert Diamond Industries and has lived in Las Vegas, NV for most of his life. In this lightly edited interview, he answered questions about Desert Diamond Industries, its products and its future.

First of all, what would you say your role is at Desert Diamond Industries, in your own words?

At first, my primary roles included working in business, sales, client services, purchasing, product development, logistics… I was involved in almost every area to some degree. As working systems developed within (Desert Diamond Industries), I started working on setting up more advanced systems such as the warranty and client service department. However, my main area of expertise lies in the acquisition of new clients and identifying clients who can best benefit from the products we design and distribute.

Why did you become a part-owner of Desert Diamond Industries?

In the beginning, Nick and I sat down and discussed the opportunity to get involved in designing and distributing safer and more reliable saw blades to government agencies and municipalities.  We knew that saw blade kickback and diamond segment loss was a big problem in the water industry. With the innovation of the Safety Blade, I knew it was something I could feel good about making the public aware of, so I committed whole-heartedly to the vision Nick started, and in turn, we are able to help thousands of people stay safer and more efficient in the field with the Safety Blade.

What was Desert Diamond Industries like when it first started out?

It was great in the beginning. We were pioneers back then. None of our potential clients had heard about the technology we were using to make the Safety Blade, so it was something that was fresh and new to them initially. Once we were able to get a single saw blade out to a client for their review, it was an earned client every single time. That’s when we knew we were on to something. Once the smaller companies/municipalities started telling us their experiences, we knew it was time to go for some larger accounts. That’s when we launched our Dream 100 campaign to earn the 100 largest municipal accounts.

Has Desert Diamond Industries grown since then?

Yes, since then we’ve expanded to distribute the Safety Blade not to only government agencies, but also the federal government, including the DOD, FEMA, naval air stations, and many civil engineering departments. We’ve developed other products with the same manufacturing technology as the Safety Blade to help welders with grinding needs. Our entire vacuum-brazed product series is designed for cutting and grinding any type of metallic, ferrous or non-ferrous application. We’re currently introducing the benefits of the Safety Blade product line to fire departments and USAR teams across the world.

Two more questions. Did you use saw blades in any professional capacity before becoming a part-owner of Desert Diamond Industries?

No. Nick had some experience using saw blades, so we had a very basic understanding of how they work. We had lots of ideas on how to build better saw blades and solve many of the problems associated with durability, performance, and safety. We knew we had to start with the highest quality materials, then test the blades we created against blades made with lower quality material to get an understanding of what makes a saw blade safer or better performing over another.

One more question. What are your future plans for Desert Diamond Industries?

Our plans are growing along with ourselves. My plans include building a network for products that are safer for clients, starting with the Safety Blade, and basically becoming a company that offers a lot more than just a product that can help save lives. We want to get involved with the community as far as getting rid of the toxic building materials that they use across the world, and we definitely want to make sure that we use something way more environmentally friendly in the future, and even though it may put us out of business, doing these things is something that’s going to benefit the entire world. So that’s what we’re after.

Brotherhood Instructors, LLC on the Fire Rescue Safety Blade (Again)

Firefighting Articles from Desert Diamond IndustriesKevin Legacy, co-owner of firefighter trainers and our partners Brotherhood Instructors, LLC, sent us a review of the Fire Rescue Safety Blade yesterday. It was so good that we decided to reproduce a lightly-edited version here:

Since September of 2009, Brotherhood Instructors, LLC has been using the (Fire Rescue Safety Blade) on our power saws. Working in the fire service and in construction throughout the years, myself and the staff of 50+ instructors employed with us at (Brotherhood Instructors) have had the opportunity to use many different types of power saw blades, whether it is teaching a student to use a power saw for the first time or responding to an emergency on the fire apparatus. It gives me great peace of mind knowing the Safety Blade is on the equipment myself and my students will be using.

As a co-owner of Brotherhood Instructors, our number one concern is the safety of the fire service and law enforcement professionals who work for and attend classes with our training company. I have seen abrasive blades have catastrophic failures causing injury to rescue personnel and civilians. I have witnessed shrapnel flying off a segmented diamond blade. I am proud to say that since we have been using the Desert Diamond Safety Blade on our power saws, there have been no injuries to staff or students due to a blade failure. During fire and rescue operations, power saws are used in situations that they were not primarily designed for. We pass on techniques that prepare our students for many different situations where a power saw may be used to affect a rescue or gain access to a fire or emergency. As with any type of hands-on training, we do have accidents when using the power saws. Saws being dropped or twisted while cutting and pieces of locks or material stuck in the blade guard are amongst the mishaps we have experienced, none of which have caused the one-piece, ruggedly designed Safety Blade to fail. The statement “Your Safety… Our Priority!!” that Desert Diamond uses has proven itself time and time again during our classes.

The way the blade is constructed also makes it very easy to use. The diamonds are adhered to the main cutting surface in a way that makes it wider than the rest of the blade, which makes for quick cuts and reduces the risk of binding and slowing the saw. The abrasives on the sides keep the blade cutting even when the operator fails to hold the saw perfectly straight, greatly reducing kickback. The way the blade is vented keeps the blade cutting nicely instead of overheating and melting through material like other blades seem to do. We put these blades through a tremendous amount of use in our classes. That being said, each Safety Blade lasts us well over a year. For us, that is a huge yearly savings in equipment costs.

A couple years ago, I was very pleased to learn the Special Operations Units of my primary job were getting the Safety Blade. We put it on our forcible entry saw and it lasted two years before we had to get a new one. Nowadays, a very common sight at a taxpayer fire or any prolonged forcible entry operation where power saws are used is a bunch of saws out of service on the sidewalk waiting for replacement abrasive blades. Meanwhile, the firefighters lucky enough to have the Safety Blade are still cutting away. In my area, we tell firefighters in the surrounding units, if we are on scene in a capacity where we are not using saws, that they can use the unit with the Safety Blade from our apparatus instead of using multiple abrasive blades or saws to complete one task.

On scene at a fire/rescue operation or training a couple hundred students on power saw operations, the Safety Blade exceeds all expectations of any blade in its class. Operator and personal safety, ease of use, cost effectiveness, and great customer service along with an unbeatable warranty – what more could you ask for?
