Because of the highly quality material, bridge saw blades are known for their durability and versatility. Furthermore, the wonderful blades prevent overheating and therefore contributing in the overall life span. If you want to achieve greater profits in the construction industry, you need to have some bridge saw blades.
Diamond blades
Diamond blades are mostly used in the semiconductor industry, gem industry and construction industry. The most common cutting materials of diamond blades include bricks, concrete, ceramics, glass, coal balls and asphalt. Although the diamond used in these saw blades is synthetic, the rigidity and toughness is exactly like natural diamond. It's because of the intrinsic value of diamond, these blades are the most expensive ones.Some blades can even cut through metal and thus increase their applications. If diamond saw blades go dull, you can increase the overall life expectancy by sharpening it.
Concrete cutting blades
Concrete cutting saw blades are among the most important blades used in the construction industry. In comparison to conventional saws, modern day concrete saws are very much effective. These blades are used for both - dry concrete sawing and wet concrete sawing. Segmented blades, turbo-rim blades, abrasive blades, masonry blades are included in the list of most common concrete cutting blades. Moreover, you can even cut some metals with concrete saw blades.
Early entry blades
The early entry blades are beautiful in design and offer long life cutting. These blades are available in two grades- basic and expert. Therefore, depending on your experience in the construction industry, one must choose a specific grade of early entry saw blade. Stainless steel and mild steel is mostly used in designing these saw blades. The early entry blades are available in different sizes and can be used in most of the manufacturing projects.

First understand what material you're cutting
Before choosing any blade for cutting asphalt, you should first understand and fully grasp the type of material to cut. Many blades are general purpose blades, and they can handle a ton of different materials. However, if your cutting need is mainly for one type of material, in this case, asphalt, it is then recommended to choose a blade optimized for this purpose.
Select asphalt cutting blade diameter
Blades for cutting road and many other blades have different widths that give different cutting power. The width of a blade determines the depth of your cut. Therefore, before choosing an asphalt cutting blade, you may need to decide how deep of a cut you wish to make.
Asphalt cutting blade device selection
When choosing the right asphalt cutting blade, it is not sufficient to only check the blade diameter; you must also know what type of cutting equipment you wish to use with the project. There are different types of saws or cutting machines with different cutting strengths.
Choice of wet and dry asphalt cutting blades
Diamond-cut asphalt blades are usually made of hard-bonded materials, so we use them to cut asphalt, which is softer than other surfaces such as concrete. They are better to use because they quickly release the grit in the pavement, making it easier to cut.
Cutting depth of asphalt cutting blade
The capacity of your blade determines the max depth of cut that your saw can achieve. If you have a large blade, you'll get a deeper cut. How deep do you want your blade to cut? It is essential to take note of as you select the asphalt blade you need.
Speed of asphalt cutting blade
Different jobs require different cutting speeds. The rotation speed can preserve or ruin it; therefore, in selecting an asphalt cutting blade, you need to know the right rate to use.
Get an asphalt cutting blade with a wide u-shaped slot
One way to differentiate blades from the other is by looking at the key slots or gullets. Gullets are spaces of air that separate the diamond segments. These slots are there to allow airflow, dissipate heat and remove slurry from the cut. It also helps in keeping the blade in good condition.
Take note of the hardness of the diamond asphalt blade
Because of the hardness of diamond, it will cut into almost every kind of material. However, your diamond asphalt blade's bond strength can either be soft, medium or hard. The bond strength of your blade determines how fast the diamonds are exposed.
Make a comparison of prices
An excellent way to decide on selecting the right blade for your saw is by comparing the asphalt blades' prices on the market. Different brands offer different rates, although they may be similar.
Tips for Using Asphalt Cutting Blade
01
Use protective gear
Before using your asphalt cutting blade, you need to get the correct protective equipment. Essential safety gear on construction sites consists of a blade guard, dust mask, protective eyewear, a helmet, ear defenders, work boots, safety gloves and high-visibility clothing.
02
Choose the right blade
Determine what material you're cutting and whether you want a rough or fine cut. Once you understand your specific application, choose a asphalt cutting blade that's right for the job.
03
Understand dry and wet cutting
Dry cutting with a blade that requires water can be dangerous, so it's essential to understand when you can cut materials dry. If in doubt, review the manufacturer's specification. Additionally, using a dry cutting technique can cause harmful silica dust to accumulate so make sure to always wear the correct mask protection.
04
Inspect and maintain your blades
Thoroughly inspect your saw and blades before you start to cut. When examining the blade, look for impairments such as cracks, chips, gouges, or missing tips. While it's normal to have some wear and tear, missing segments or damaged blades can slow down your work and become serious safety hazards.
Concrete Vs. Asphalt Cutting Blade: What's the Difference
Concrete diamond blade: These blades are typically designed with a harder bond matrix and a higher diamond concentration. The hardness of the bond helps the blade maintain its integrity when cutting through the abrasive nature of concrete.
Asphalt cutting blade: Asphalt blades have a softer bond matrix to allow for better cutting performance in the relatively softer and less abrasive asphalt material. They contain a lower concentration of diamonds.
Concrete diamond blade: These blades often use larger diamond grit sizes, which are more effective for grinding through the hard aggregates and abrasive materials present in concrete.
Asphalt cutting blade: Asphalt blades use smaller diamond grit sizes to help maintain the blade's sharpness and cutting efficiency when working with softer asphalt.
Concrete diamond blade: Concrete blades are designed for slower cutting speeds because concrete is a harder and more abrasive material. Slower cutting helps maintain blade life and prevents overheating.
Asphalt cutting blade: Asphalt blades are optimized for faster cutting speeds since asphalt is a softer material. The softer bond matrix and smaller diamond grit sizes allow for quicker cuts.
Concrete diamond blade: When cutting concrete, the blade typically experiences slower wear and has a longer lifespan due to its harder bond and larger diamonds.
Asphalt cutting blade: When cutting asphalt, the blade may wear more quickly because of the softer bond and smaller diamonds. Frequent dressing or sharpening may be required to maintain cutting efficiency.
Concrete diamond blade: Water cooling is often recommended when using concrete diamond blades to dissipate heat and reduce blade wear.
Asphalt cutting blade: While water cooling can also be used with asphalt blades, it is not as critical due to the lower heat generated during cutting.
Tips for Cutting Asphalt With a Asphalt Cutting Blade
Safety first
Before diving into asphalt cutting, prioritize safety. Wear appropriate personal protective equipment (ppe) such as safety glasses, ear protection, gloves, and a dust mask. Make sure the cutting area is clear of obstacles, and establish a safe working zone to prevent accidents.
Choose the right equipment
Selecting the right cutting equipment is essential for a successful asphalt cutting project. Diamond blade saws are widely regarded as the best choice for cutting asphalt due to their durability and ability to maintain sharpness through abrasive materials. Ensure that the saw is equipped with a water cooling system to control dust and minimize overheating.
Inspect and prepare the asphalt surface
Before making any cuts, inspect the asphalt surface for any potential hazards or obstacles. Clear the area of debris, and mark the cutting lines with chalk or a temporary paint marker. This step ensures precision and helps prevent any accidental damage to surrounding structures or utilities.
Control dust emission
Cutting asphalt generates a significant amount of dust, which can be harmful if inhaled and can reduce visibility on the job site. To control dust emissions, use a wet cutting method by incorporating water into the cutting process. Many asphalt saws come equipped with a water supply system to keep the blade cool and control dust. This not only enhances safety but also improves the efficiency of the cutting process.
Optimize cutting techniques
Achieving precise and straight cuts requires proper technique. Start the cut with a shallow depth and gradually increase it until the desired depth is reached. Move the saw at a consistent speed to ensure a smooth cut. Additionally, consider making multiple passes for thicker asphalt, adjusting the blade depth accordingly.
Regular maintenance of equipment
To ensure the longevity and efficiency of your cutting equipment, perform regular maintenance. Keep the saw blade sharp, check for any wear or damage, and lubricate moving parts as needed. Regular maintenance not only extends the life of your equipment but also ensures optimal performance during every cutting operation.
Proper waste disposal
Once the cutting is complete, proper disposal of asphalt waste is crucial. Collect and dispose of the cut pieces in accordance with local regulations and environmental guidelines. Recycling asphalt is a sustainable option and may be available in your area.
How to Dress or Sharpen a Asphalt Cutting Blade？
Step 1: Safety first
Before beginning the dressing or sharpening process, it's important to take safety precautions. You'll need to wear safety goggles, earplugs, and a dust mask to protect your eyes, ears, and lungs from debris and dust.
Step 2: Removing the blade
The first step in the dressing or sharpening process is removing the blade from the saw. To do this, you'll need to follow the asphalt cutting blade manufacturer‘s instructions for your specific saw. In most cases, you'll need to unplug the saw, remove the blade guard, and loosen the blade's retaining bolt or nut.
Step 3: Cleaning the blade
Before dressing or sharpening the diamond saw blade, you'll need to clean it thoroughly. You can do this by soaking the blade in a solution of warm water and dish soap for 15 to 20 minutes. After soaking, use a soft-bristled brush to scrub the blade gently, removing any debris or build-up.
Step 4: Dressing the blade
Be sure to use a light touch when dressing the blade. Applying too much pressure can cause the dressing stone to wear down the blade's diamonds, reducing its lifespan. Dress the blade until you've removed all of the build-up and the diamonds are exposed.
Step 5: Sharpening the blade
To sharpen the blade, you'll need a sharpening stone or file. These are abrasive tools used to restore the blade's cutting edge. To use the sharpening stone, hold it at a 45-degree angle to the blade's surface and move it back and forth across the blade's cutting edge, applying even pressure.
Step 6: Checking the blade's condition
After dressing or sharpening the blade, it's important to check its condition before reattaching it to the saw. Inspect the blade for any cracks or damage that could affect its performance or safety. If you notice any damage, it's best to replace the blade.
Step 7: Reattaching the blade
Once you've checked the blade's condition, it's time to reattach it to the saw. Follow the manufacturer's instructions for your specific saw, being careful to tighten the retaining bolt or nut securely.
Step 8: Testing the blade
Before using the saw, it's important to test the blade to ensure that it's cutting properly. You can do this by making a test cut on a scrap piece of material. If the blade is cutting smoothly and efficiently, you're good to go. If you notice any issues with the cut, you may need to repeat the dressing or sharpening process.
