When to Replace a Diamond Saw Blade

Monitoring the blades on your diamond saws for wear and tear is important for ensuring your safety while working on stone cutting projects.

Diamond blades, unlike a woodworking saw blades, are more difficult to determine if a blade needs replacing. There are no tell-tale sign of chipped carbide teeth or wood burning to easily let you know that it’s time to replace the blade. Instead, as a diamond saw blade is used to cut materials, the diamonds that do the cutting wear down over time. Knowing the signs of a dull blade will help you decide when to replace your diamond saw blade.

The easiest way to figure out if your diamond blade is dulling is when it simply doesn’t do the job as well. The blade will cut slower than before, making it more difficult to make clean cuts as you would with a new stone blade. Visually, this will often look like the blade is becoming smooth. Closely inspect your blade (while the stone saw is not plugged in) to check to see if the diamonds have been smoothed over from wear. If the diamonds wear down, it’s time to buy a new blade.

In the same vein, if the diamond rim is completely worn down to bare steel, it is time to buy a new blade.

With aggressive use of a diamond saw blade, it is possible that individual segments of the blade have worn down. If your cutting teeth have chipped off or worn away completely, it will continue to degrade with use.

Diamond Tool Store recommends taking your time while making cuts to concrete or stone. Allowing the tool to do the work is important for extending the life of your diamond blade. When you press too hard against your workpiece, it does tend to wear blades down much faster than you otherwise need to.

Remember, safety is no accident. Using dulled blades can result in injury.

Title: Floor Grinder Buying Guide: What Floor Grinder is Best

Meta D: Diamond Tool Store understands that buying a floor grinder can be a large investment. Learn from our experts the best way to shop for floor grinders!

Floor Grinder Buying Guide

Buying concrete grinding and polishing equipment can be an incredibly daunting task. With so many different manufacturers offering so many variations of equipment, all promising that they have the best concrete floor grinder, how can someone possibly choose without having buyer’s remorse?

Unfortunately, there is no easy answer. With so many different brands and different applications, a floor grinder isn’t simply the same as buying a grinding pad. If a grinding pad brand lets you down, you simply stop buying from that brand. But with a floor grinder, there is a significant investment involved. Consider the following questions when shopping for a floor grinder:

What floor grinding equipment do you already have?

Considering what equipment you have available to you is important to determine what type of equipment you should buy in the future. It may sound counter-intuitive, but without an updated inventory of your equipment, you might be going into a large purchase blind. For example, if your dust collector (for dry grinding) is on the brink of needed replaced as well, it can help to buy both at once for a discount.

What capacity are the machines that you have already? If you are already very happy with your equipment, but are buying a machine to replace an older model, then the size and features you need are already figured out.

Are you buying to expand your capacity? If you’ve lost a few bids based on the number of man hours you needed because your existing floor grinders are too small to facilitate larger jobs, upgrading your machine size is a good way to help you be more competitive on larger jobs.

How are your current machines powered? The most common method of powering floor grinders is electric. However, there are propane and gasoline powered floor grinders that are on the market which can help keep you from wasting time wrangling electric cords and thus increasing the number of hours you need to complete a job. Even if you’re currently using an all electric setup, would it be a good idea to take this opportunity to transition to alternative power sources?

What size grinding projects do you already scheduled?

When buying new equipment, it is important to address financing. How are you going to pay for your new floor grinder? If you’ve already have a positive cash flow in place, with a sizable “rainy day fund” for equipment failure or upgrades, then this is much less of an issue. However, if you’re just starting out in starting a floor grinding business, determining what local demand is calling for can help determine which machine to buy. Are you going to be targeting home-owners who need their garage floors grinded and leveled? Does that shopping mall in town have a bidding process open for a massive restoration of their entire facility? The type and size of floor grinder you buy can be very dependent upon what types of jobs you already have lined up. If you’re just starting out, find a financial partner to help finance your purchase can be very useful.

Further, if you already have quite a few grinding jobs on your plate, perhaps instead of buying one super-capacity machine, buying two smaller machines would be helpful. Do you have employees that are just “idle hands” without more equipment, or are you a sole entrepreneur? All of these factors play a role in your decision.

Do you have access to experts?

Unfortunately, because there are so many variables for each business, it is impossible to give one-size fits all advice for every business. Reach out to your professional network. Was there someone who helped bring you into the concrete industry? Talk to your mentors and get their opinions.

We would recommend caution when talking to manufacturing representatives. Every sales rep has an incentive to tell you that their company creates the end-all-be-all concrete grinding machine. It’s much better to talk to people in the industry or experienced sales reps that sell multiple brands to give much better advice.
