I do professional knife, and tool sharpening as a side hustle. I had never sharpened circular saw blades beforeI but after watching a few YouTube videos of others using this tool, I saw a opportunity to add saw blade sharpening to my services and be able to make the tool pay for itself in a short period. I already contacted a few local carpenters and they are excited to hear the don't have to send blades out for a week or two to get them sharpened. The tool did arrive with some minor damage to the metal cap on the motor housing that I was able to easily fix, no damage to the motor. The cup washer that holds down the saw blade was about 1/8 too short to contact the saw blade. Added a couple rubber feet to the washer and I think it's even better now. The radial runout on the diamond sharpening disc was measured at 0.020 (twenty thousandths) which I felt was a little excessive. It does seem to have gotten better with a little use. Although in a different time zone, the customer care dept was very responsive to my emails, it took about 18 hours to respond. Take lot of pictures of the box before and after opening, contents of the box, and any damage you find. You will also need to have pictures of the labels on the box, so don't throw it away. Very important to give the saw blade a good soaking in laundry detergent or some Simple Green Purple cleaning solution BEFORE you start to sharpen to remove all the pine pitch and sap on the blade teeth. The pitch and sap will clog up the diamond blade very quickly if you don't. Watch some of the YouTube videos on how to set the tool up for blade sharpening. Another tip is to buy yourself a digital angle gauge to check the level of the motor (see photo), blade, and blade platform, they should all be the same, or very close. I took a 10\", 60 tooth blade that was just burning into wood when you tired to cut with it, it would smoke as soon as it got into the wood. Spent about 15-20 minutes getting the blade set up and

Bit fiddly to set up as the adjustment screws are underneath, where they need to be, however once set quickly sharpens blades. Replacing socket head bolts with regular hex head bolts will help as it will allow the spanner to come in from the side

Heavy cast iron but cheap plastic knobs. Overall it is good for the money. Not perfect nor bad.

Great little machine, looked up you tube for a demo on how to use it, once you get use to using it, it does a great job and saves going to the saw doctor to get your blades done

As usual, fast delivery from VEVOR. Successfully sharpen my old 305mm mitre circular saw. Cuts like new. No more purchases of new blades or searching for a saw sharpening services.

While it works well, they don’t give any instructions for use or assembly. Any reasonably competent DIY’er can figure it out but it’s frustrating.

In my experience, the Circular Saw Blade Sharpener has some issues that may affect its overall performance.One major issue is the inaccurate diamond grinding wheel bushing, which can cause the grinding wheel to wobble by 5 to 8 thousands. This can result in an uneven grind on the circular saw blade, which can affect its cutting performance.Additionally, the circular saw blade bushing can be either under or over-sized, which can also cause an inaccurate grind. If the bushing is too thick, the clamping washer may not reach and clamp the saw blades properly, leading to further inaccuracies.Another issue is the play in the aluminum slide, which can cause the circular saw blade to wobble during the sharpening process. This can also result in an inaccurate grind.Overall, while the Circular Saw Blade Sharpener may be a cost-effective option for some users, it may not be suitable for those who require precise and accurate sharpening. It is important to note that these issues may be addressed by proper maintenance and adjustments, but users should be aware of the potential challenges before purchasing this product.

I was intending to make a sharpening jig until I saw this advertised. Awesome product for the money. Provides accurate results

This thing is fantastic, only fault is that the instructions are a bit hopeless. Set up was a bit difficult, but once I got used to it, it was not too bad. The result is perfect and it has more than paid for itself with the blades I have sharpened so far. Very Happy

The saw blade sharpener works well, once you figure out the instructions, which are somewhat obscure. Fortunately we have YouTube and a bunch of people who have gone on to work out how to use the machine. I spent 20 minutes watching a 'how to' video and then sharpened about 8 blades, from 165mm to 250mm diameter in short order. Most were for ripping but a couple were crosscut blades. The machine was easy to set up and sharpening proceeded smoothly. The only issue I have is that all the bosses are metric, so I had to make one for a 5/8 inch hole. Even with this ommision I am very happy with this tool and I would recommend it to anyone.
