Circular Saw Blade Sharpeners Buying Guide

You might be asking yourself what a circular saw blade sharpener is? Simply put, it is a power tool that holds a circular saw blade in place while a rotating grinding wheel is moved across the exposed saw tooth surface in order to grind it. The finished tooth surface will cut more effectively than it did when it was dull.

advantages of having a circular saw blade sharpener

First off, you will provide an accurate grind angle. These sharpeners are designed to be set at an angle. This will also allow you to repeat that angle for a consistent sharpening on each saw blade tooth and keep the proper tooth configuration.

Secondly, you will be able to sharpen the circular saw blade more quickly than with a file by hand. It may take a moment to set the sharpener up, but it will allow you address each tooth quickly after.

Next, a circular saw blade sharpener will shine when doing more than one blade. Once you have the angle and size of the saw blade set you will move quickly through multiple blades. I recall watching my late grandfather sharpen his saw blades by hand and I can say these machines will do the job faster.

Finally, you will save money in the long run since you won’t have to pay someone else to sharpen your blades or, worse yet, buy a new circular saw blade each time your old one becomes dull.

Who would benefit most from having a circular saw blade sharpener?

Instead of just answering with “everyone,” let’s take a look at who might not be interested in a sharpener. These may not be necessary for your shop if you are a hand tools only woodworker, although some woodworkers use a sharpener on various types of saw blades and drill or router bits. There are also those, who I believe are mistaken, that believe that a used circular saw blade cannot be sharpened effectively once it becomes dull.

Anyone outside of the two groups mentioned above would benefit from this type of accessory.

The goal of resharpening your circular saw blades is to reuse them, saving you money. Buying one of these machines may not seem to be saving you money at first, but once you sharpen just a few circular saw blades, the blade sharpener will have paid for itself (especially if you tend to use more expensive circular saw blades).

If you work in construction or manufacturing you will notice savings quickly. If you have a home workshop it may take a bit longer unless you dull blades quickly by making batches of projects or many pieces of furniture.

Things To Look For in circular saw blade sharpeners

When shopping for this type of tool, there are some important considerations you must keep in mind.

Motor block tilt

The sharpener will need to tilt in order to produce the proper angle as it grinds the tooth. This will help you to maintain the configuration. Most products will offer tilt angles of 25-degrees, so if you find one with less then look elsewhere.

The maximum saw blade size

Circular saw blades can range on average from 6.5-inches to 12-inches, with some blades going up to 16-inches. While most personal workshops use the smaller blades, you can encounter many of the larger ones on the Jobsite. Look for a unit that can handle blades up to 10-inches, or larger if you use a chop or miter saw with larger blades.

Saw blade support

The saw blade will be attached with a tightening screw to the sharpener. With most models, there will be a small extension rod that provides extra support. Other designs will make use of a table surface.

Select extra support that you can afford, but keep in mind that this added rigidity will help to keep the blade in position as the grinding wheel moves across the tooth.

Grinding and polishing disks

These products make use of disks to grind against the saw tooth blade. They will come in either a Diamond or Emory surface. The Diamond wheels tend to be for course removal of a lot of material (and carbide teeth) while the Emory wheel provides a finer edge to the tooth (and for steel teeth).

You can also make use of a polishing wheel to remove rough edges and to clean pitch build-up instead of using a hand brush with your preferred cleaner.
