Now you might be thinking, “ But wait, how is this different from using a power grinder?“. You can also sharpen your hedge trimmer blades using a Dremel rotary tool. How to Sharpen a Hedge Trimmer Using Dremel To finish all you need to do is continue with that same process on each tooth all the way down the bar. Repeat this process for the opposite side. The grinder will work much faster than the file, so be careful not to take too much off the tooth. You need to be careful to maintain that same angle while you grind. Step 3Īgain, the same surfaces will need to be ground but now we will use a grinder instead of a file. With that secured, you can begin to grind. Start by clamping the bar of the hedge trimmer to a bench vice just so it doesn’t move around while you are grinding. Of course, whenever you use a power tool you will want to be wearing the appropriate safety gear – hearing protection and eye protection. Either way, here is how I’d do it: Step 1 The video above also covers this method, so you can check it out if you are more of a visual type. The reason for this is that it’s very easy to grind off too much material from the blade, greatly lowering its lifespan. However, I wouldn’t recommend it to beginners. This method is great if you are experienced with the power grinder, as it’s much faster than using a mill file.

You can draw the cutting edges against a sheet of paper to test for sharpness. Once you are done filing, wipe down each blade with a wet rag. The material may lose strength if you file away more than this. The blades have a wear threshold of 5mm, so ensure you don’t file away too much of the blade. Sharpen all the sides of each blade on each side. Continue this until the edge looks shiny. You can easily find this in your equipment’s instruction manual. Step 4Įnsure you maintain the specified sharpening angle. ![]() ![]() The file is designed to work this way to guarantee an optimum cutting edge. Push the mill file toward the cutting edge and not back and forth. Ensure you keep the file at the same angle as the cutting edge. Run the mill file down each cutting edge. Remove the bolts that hold the blades together and clamp them into a bench vice. How to Sharpen a Hedge Trimmer With a Mill File Step 1 And if it’s a double-sided blade, we have the same surfaces on the back so there are a total of four/six surfaces that need to be sharpened per tooth. With the blades aligned, you can see on each blade that there are two or three (depending on the type of the blade) different surfaces you need to sharpen. The handle on the screwdriver will keep you from damaging the blades and they will move the blade to that distance to align them perfectly. Put it between the blades and use it as a pry bar. To get that fine bit of alignment, you can take the handle of an old screwdriver. Simply press the two blades together and you can get them pretty close to being right in alignment that way. I found the easiest way to align the blades is to start by hand. You are dealing with sharp blades so it is smart to put on some good gloves to protect your hands as you align these blades and do the sharpening.
