How Do You Choose the Best Sharpener for Circular Saw Blades?
A quality circular saw blade sharpener can help you extend the life of your
expensive blades. But with so many sharpeners on the market, you can hesitate when picking the proper one. Here are a few factors I’ve listed you should consider when you shop for a circular saw blade grinder tool:
1. Construction Material
One of the most important factors I suggest you consider is the construction material of the sharpener. The four most common materials are steel, carbide, CBN (cubic boron nitride), and aluminum. Each construction material has its strengths and limitations.
Steel is the most affordable option, but it will require more frequent sharpening than carbide or CBN. Carbide is more durable than steel, but it is also more expensive.
CBN is the most expensive option, but it will stay sharp longer than either steel or carbide. Aluminum is the lightest option, but it is also the least durable. You can find some good middle-of-the-road options made from steel or aluminum.
2. Motor Power and RPM
An electric motor’s power determines how much force is applied to the blades when sharpening. A higher-power blade sharpener will remove material more quickly but can also damage the blades if not used carefully. So, I advise a lower-power sharpener for most home projects, which will do the job.
The RPM, or revolutions per minute, measures how fast the abrasive wheel spins. As the RPM increases, the blades will be sharpened faster. RPMs that are too high can cause the blades to overheat and warp.
3. Grinding Wheel Size
To determine the correct grinding wheel size for your saw blade, start by measuring the diameter of the blade. Consult the manufacturer’s instructions to find the recommended grinding wheel size for that particular model of saw blade.
If you cannot find the manufacturer’s recommendations, let me tell you a good rule of thumb is to choose a grinding wheel slightly smaller than the diameter of the blade. For example, if you are sharpening a 10-inch saw blade, you would use a 9-inch grinding wheel.
Using a grinding wheel that is too large can cause overheating and damage to your saw blade, so it is important to choose the right size.
4. Cooling System
My analysis found two cooling systems for these sharpeners: air-cooled and water-cooled. The air-cooled system will use a fan to cool the motor and blades, while the water-cooled system will use a water pump to circulate water around the motor and blades.
There are benefits and drawbacks to both types of cooling systems, so you will need to decide which one is best for your needs. Air-cooled sharpeners are generally more expensive than water-cooled sharpeners but do not require as much maintenance.
Water-cooled sharpeners are less expensive up front, but they may require more maintenance over time. Either way, you will need to ensure that you get a sharpener with a good cooling system so that your blades will stay sharp and last longer.
5. Fewer Vibrations
Before you buy a circular saw blade sharpener, I recommend you consider how much vibration dampening it has. The less vibration your sharpener produces, the easier it will be to use, and the less wear and tear it will do to both your saw blades and your circular saw.
Manufacturers achieve this goal in a few different ways, so it’s worth researching to find the model that will work best for you.
One common solution is using rubber feet to isolate the sharpener from its resting surface. This can effectively reduce vibrations, but it also has the potential to make the sharpener less stable, so be sure to read reviews carefully before making your final decision.
Another option is to use a weighted base, which helps keep the sharpener steady. This can be a great choice if you have a particularly powerful saw or plan on using your sharpener for extended periods.
6. Blade Adjustable Angle
The adjustable angle of a circular saw blade sharpener is another crucial thing to look for when buying one. I believe this is important because it will determine how sharp your blades can get and how often you need to sharpen them.
If you have a lot of different size blades, you will want to ensure the sharpener you choose can accommodate all of them. Also, if you do many different cuts, you’ll want to ensure the angle can be adjusted to suit each type.
7. Portable Design
A big consideration with a blade sharpener is portability. You may need it portable in the shop or on the job site. Some sharpeners are small and compact enough to fit in your toolbox, while others may be too bulky. If you plan on taking your sharpener to different worksites, choose one that will be easy to transport.
A heavier unit may be more difficult to transport but will likely be more durable. Make sure you pick the right model for your needs to protect your blades. You can find a good portable circular saw blade sharpener from our list above.
When should I sharpen a circular saw blade?
To keep your circular saw blade in top working condition, I recommend sharpening it regularly. However, figuring out when to do so can be a bit of a challenge. As a saw operator, you must check the blade every few uses for signs of warping or damage.
A dull or warped blade cuts poorly and can be incredibly dangerous, increasing the risk of kickback or other saw-related accidents. As you examine your blade, watch for warping, chipping, or other signs of damage, and don’t hesitate to invest in a new blade if necessary.
How many times can I sharpen a circular saw blade?
According to my evaluation, a circular saw blade can be sharpened 2 to 3 times, depending on your blade type. Professional quality blades with a standard-width carbide tip typically last longer and can be sharpened more times than a thin kerf blade.
Don’t be tempted to keep sharpening your blade beyond the recommended number of times, as it can become too thin and ineffective. However, it’s worth noting that sharpening a dull blade is much cheaper than purchasing a new one, costing only a third of the price.
Can I sharpen old circular saw blades?
Yes, you can sharpen old circular saw blades. It is a common practice among woodworkers and DIY enthusiasts alike. However, remember that the frequency of sharpening your blades will depend on how often you use them and the material you’re cutting.
Keep your blades sharp when needed so your saw runs better. So, if you have some old saw blades lying around and want to give them new life, don’t hesitate to sharpen them and put them back to work.
Upgrade Your Woodworking Game with a Circular Saw Blade Sharpener
If you’re a woodworking enthusiast, a circular saw blade sharpener is a must-have tool. Besides extending the life of your saw blades, it improves the quality of cuts and keeps you safe. You don’t have to spend a fortune to get a premium-quality sharpener; you can find reliable models at affordable prices.
However, you should invest in a sharpener that suits your needs and budget, offers multiple sharpening options, and delivers consistent results. I’ve reviewed some of the top models on the market and given expert recommendations to choose the suitable one.
All the products I have discussed above are of the highest quality, but the VEVOR carbide-tipped saw blade sharpener tops them all. Its powerful operating motor and water-cooled structure caught my attention, a feature that sets it apart from the competition.
