We will continue to search out concrete tools and accessories to help our audience meet the upcoming OSHA Silica Dust standards, June 23, 2017. Cutting concrete outdoors with a gas cut-off saw and water hookup probably won’t change much however for indoor concrete cutting or dry cutting we will definitely see some new challenges. These new Core Cut C14 ($599) and C16 ($999) Concrete Saws are electric but offer serious power much closer to gas than we have seen in the past and can be used wet or dry. Many 14”+ electric saws currently don’t have water hookups or dust collectors and aftermarket attachments can be questionable. The new OSHA spec for dust collection require near HEPA filtration, automatic filter cleaning and 25 CFM per 1” of blade diameter in cutting. For a 14”saw that’s 350 CFM, you’re not going to find that at your local hardware store.

Everyone knows when you pour fresh concrete you need to build-in control joints so that if/when the concrete is stressed there is a controlled path for how the concrete will crack. This is the common practice but there are several ways which those concrete joints are installed. “Early Entry” saw cutting is method which refers to cutting while not fully cured or 2 – 10 hours after being poured. Husqvarna Soff-Cut is a well know name for Early Entry cutting but there a couple new kid in town from Diamond Products Core Cut with First-Cut Early Entry Saws. Of course they’ve got several reasons why their saws are best.

We’ve all hit an off-ramp going a little faster than you’re supposed to and been startled by the rumble strips. It really is the best way to alert drivers there is a change in the roadway ahead and you need to slow down. Have you ever wondered how those rumble strips get put there? Recently we had an opportunity to work with our friends at our regional DOT as well as Diamond Products who makes a nice converts kit for their most popular walk behind concrete saw Core Cut CC6571. The kit very easily turns the saw into a transverse rumble strip machine with a 4” width capacity.
The Core Cut CC6571D-36 large concrete saw from Diamond Products is a powerful, full sized self-propelled concrete saw that gives maximum large saw performance and output at the lowest price in its class. The very smooth running, liquid cooled, four cylinder Kubota diesel engine is very powerful yet has moderate fuel consumption, and can be used in a wide range of contractor and industrial applications. Easy to fit into a trailer with water tank and other necessary accessories. This unit definitely has the power needed for installing the 4” wide rumble strip.
Transverse rumble strips, also referred to as bar markings, are placed across the traffic lane to make sure motorists are alerted to hazards ahead, such as areas of pedestrian activity, bends in the road or intersections. They are typically useful where drivers have been travelling continuously at high speeds for a long period of time.
The 4” blade spacing kit (6010632A) can be added to the standard saw with very little additional work. The kit includes a wide guard to accommodate the four inch wide stack of blades and spacers. The (16) 12”x.250” blades and (15) spacers that go between each blade are added as shown below. Finally, the guard is installed. Now you are ready to install precision 4” transverse rumble strips.
The next step is to determine transverse rumble strip layout. Touch the diamond blade head to the roadway surface with the engine off and set the depth indicator to 0”. Now, start the engine and lower the diamond head down until the depth indicator reads the depth specified for your rumble strip. Set your depth stop on the saw so the head can go no deeper than the amount required for the rumble strip specification. Finally, begin your pass, making sure your travel speed is slow enough that the saw does not ride up and give you inconsistent depth.
The CC6571D-36 concrete saw has a transverse mounted Kubota diesel engine. It is rated at 66 horse power and its transverse mounting makes this saw the most maneuverable of other large saws. The engine is protected by an advanced cyclone air filter system for maximum engine life. The liquid cooled, four cylinder engine is a very smooth running power plant ever on such a large saw.
This saw includes a hydraulic raise and lower system for precise depth control and a dash mounted depth indicator for improved operator control. The saw features self-propelled operation with an Eaton transmission and two position handle bars for increased operator comfort.
The blade guard and blade can be mounted on either the right or left side for sawing in difficult to reach or tight areas. The saw is generally used with water, but may be used in dry applications with the correct type of blade. This Core Cut large saw has an oil bath blade shaft which means your operators won’t have to grease any grease fittings, leading to dramatically longer blade shaft bearing life. Finally, it has a belt tensioning system that is superior to any other large saw belt tensioning system, which means more power to your blades as well as longer belt life.
For any questions on walk behind concrete saws, the rumble strip kit or diamond blades in general contact the experts at Ohio Power Tool 800-242-4424. These guys have extensive training in cutting a wide variety of materials and applications.

When cutting concrete you’ve got some choices to make, first is are you going to cut wet or dry? In most situations wet cutting is the recommended choice because this will keep dust down and the blade from over heading. Of course wet cutting is messy business and slurry gets everywhere. In block or other less dense material dry cutting is a good option but you’ll create huge clouds of silica dust which is not safe to breath. To get a useable depth of around 5” you’ll need a larger saws with a 14” blade which are most commonly gas powered to get enough ass behind it. These are ok for working out in the open but never fails we constantly hear of people using these in poorly ventilated areas and breathe in dangerous levels of carbon monoxide fumes. Diamond Products new Core Cut Electric Saw C14 ($699) looks to address many of these concerns and possibly change the way many cut concrete. (more…)

When it comes to selecting the right walk behind concrete cutting saw there are a lot of important considerations including: costs (upfront, operating, repair), capacities/speed, reliability, features, maneuverability just to name a few. Below we’ve highlight a couple of what we think are very good options from a Small to X-Large size Walk Behind Saws for cutting concrete or asphalt. (more…)

Just announced at the 2013 World of Concrete, the Diamond Products Cut Core CC6566 (06/2016 * Note CC6566 is now CC6571 Tier4 Final) walk behind saw might not find a home in every garage in America but if you are in the market of a large walk behind saw it should definitely be on the short list of considerations. The goal of this new saw design was a clean, simple, trouble free design that would be tough as nails and put out the most power they could squeeze into the frame. The saw is big but still small enough to fit through a standard 36” door way, so fairly compact for a saw fitted with a 42” concrete diamond blade. Keeping the cost down on this saw was another very big driving force as well, not only in initial purchasing price, which starts at $25,000 but also to greatly reducing operating costs, expensive repairs and downtime.

As you may or may not know, I love the Dragon Saw. There is nothing about it that I do not think is great, and I routinely find myself coming up with reasons why I would need to Dragon Saw things (like opening cans, changing the cat’s litter, etc.). Unfortunately, my wife is less than happy when I use my Dragon Saw in the house. She says the exhaust fumes from my gas powered Dragon Saw give her a headache. I am not sure I am ready to buy a hydraulic power pack and switch to a hydraulic powered Dragon Saw, but my inability to use the Dragon Saw in areas where a gas powered saw would not work was starting to get to me. Luckily, Diamond Products saw the need for a Dragon Saw that could be operated safely without ventilation and without the need of a hydraulic power pack. Allow me to present the Diamond Products Electric Dragon Saw 46095. (more…)

When it comes to bridge replacements this is about as small of a project as they get, but it is a simple way to cover all the basics and we found it very interesting. We followed this crew as they competed each step of this work. We also talked with professionals on larger jobs and got some additional input for how this process would work on bigger job that might go the length of several football fields one hundred feet off the ground. Of course we will also take a look at several of the essential tools involved in this kind of operation, large or small. (more…)

There are several options to consider where you want to drill a hole into concrete, and for anything larger than 1-2” diameter you will probably want to consider using some form of a core drill bit. Of course, not all concrete core drill bits are created equal, and selecting the right core bit will depend greatly on the type of concrete material, depth, wet vs. dry and specific application. We will take a very quick look at the different types of core drills and core bits available. (more…)
