Circular Saw Blade Sharpener: The Best 2023 Options

FACTS CHECKED BY  NICOLE PAV 

Working with a blunt circular saw poses two problems- the blunt blades give a rougher finish, and the saw motor works harder, which makes it burn out sooner.

A circular saw blade sharpener sharpens the saw blades much faster than a file and saves you tons of money you would use on professional sharpening.

Moreover, a saw blade sharpener holds the circular saw blade at an accurate grind angle to allow consistent sharpening on each tooth, thus maintaining the proper tooth configuration.

The question is, which is the best circular saw blade sharpener?

To cut to the chase, here are the top 3 saw blade sharpeners we recommend based on quality, power, and precision.

Types of Circular Saw Blade Sharpeners

This post has shed light on a specific type of circular saw blade sharpener to save time and energy. However, different types of sharpeners are suited for different situations and budgets.

Manual

Manual sharpeners are operated by hand, and they are the cheapest option. Though they get the job done, they are not the best in accuracy and speed.

Semi-supported

A semi-supported sharpener comes with a bench for support. It is firmly secured on the bench and can sharpen different circular blades, but you must manually change the grinding wheels.

Electrical

Finally, electrical sharpeners are the most popular thanks to their accuracy, speed, and ease of use.

They have fully automated features to control the process, and the edges tend to hold much longer. An electric sharpener is a way to go if you use some of the best circular saw blades.

Factors to Consider When Choosing the Best Circular Saw Blade Sharpener

When shopping for a saw blade sharpener, here are important considerations.

Motor block tilt

A sharpener needs to tilt to give the proper angle as it grinds each tooth. It helps maintain proper configuration and eliminate unevenness. The best sharpeners offer a tilt angle of 25 degrees.

The maximum saw blade size.

The average circular saw blade is 6.5-12 inches in diameter, though you can find 16-inch jobsite options. The best sharpener for you is one that can handle the blade size you have, preferably up to 10 inches.

Saw blade support

A semi-supported sharpening machine solves all the support issues. But if you use a manual or electric sharpener, you need extra support to hold down the blade during sharpening. It is where a saw blade support comes in, even if you have screwed in the saw blade to the sharpener.

Grinding and polishing disks

With high-end sharpening tools, you will see a Diamond or Emory surface. These are grinding wheels used to grind against the saw tooth blade. The diamond wheel is for course removal, while the Emory wheel ensures finer edges.
