If you have ever wished you could sharpen your chainsaw’s chain at a different angle than 0 degrees, then this article will teach you how to sharpen chainsaw chains at fifteen, twenty, or thirty degrees. This article isn’t intended to be a complete guide to sharpening saw chains, but instead to provide you with useful information. You’ll find that there are many factors to consider when choosing the proper angle for sharpening chainsaws.
15 degree angle
There are three main types of sharpening angles for chainsaws: flat, fifteen, and twenty-five degrees. These recommended angles are just starting points, and most users can find success using them. Choosing the best angle for your chainsaw depends on the type of wood you plan to cut, though. For red oak, you may want to optimize the chain’s angle for cutting, and Christmas trees are a good example. For general wood-cutting applications, pick the standard angles.
0 degree angle
Before sharpening your chainsaw chain, you should engage the brake on the saw. Then, flip the saw in your vise to work on the other side. Place the file guide between the two rivets on the chain. This guide should have arrows pointing to the nose of the bar. Also, use a flat file or raker gauge to measure the height of the chainsaw’s teeth. Then, mount a round file in the file guide and hold it at a 30 or 35 degree angle to the bar. If you’re using a table vise, you can stabilize the saw and walk around to the other side of the chainsaw while sharpening the chain.
25 degree angle
When sharpening a chainsaw chain, it is best to start by measuring the teeth on each tooth of the chain at the front and back. Then, you can file down each tooth to its proper depth. File down each tooth to its proper depth at least once every three to four sharpenings. Make sure to wear protective gloves when sharpening a chainsaw, and to hold the saw safely.
30 degree angle
The best way to sharpen a chainsaw chain is to follow the rules for proper filing. The proper angle should be at least 30 degrees from the guide rail. The angle must be more when the chainsaw is used on hard wood. A filing gauge or sharpening grid is a great aid for keeping the angle correct. The file should be gripped only while moving forward and lifted slightly when reversing the motion.
40 degree angle
The recommended angle to sharpen a chainsaw chain is often marked on the tooth by a small line that helps with hand filing. If this guide isn’t visible, start by filing the chain at a 30-degree angle and slowly increase it to 40 degrees. Once you’ve reached the desired angle, pull the chainsaw from the log and continue the cutting process using the same downward motion. If you need to sharpen your chainsaw chain on a regular basis, however, you can use the recommended angle.
