How to Sharpen a Chainsaw With a Dremel

Save

Over time, the teeth on your chainsaw will get dull and no longer cut as well. You need to sharpen those teeth, or else you may find yourself needing to replace the chainsaw altogether. A Dremel sharpening kit can help you easily sharpen the chainsaw teeth, and it can be custom fit for whichever size teeth your chainsaw has.

Things You'll Need

  • Dremel sharpening kit with grinding wheels
  • Chainsaw
  • Select the grinding wheel for the Dremel tool that will work with your chainsaw's teeth. There are three cylindrical grinding wheels with the tool: The blue wheel measures 5/32 inch, the orange one measures 3/16 inch and the pink is 7/32 inch. Find out which wheel fits in the inside curves of the chainsaw teeth.

  • Assemble the Dremel tool by inserting the correct grinding wheel into the hole on the Dremel motor. You'll also need to hook up the cylindrical spacers depending on the wheel you're using; you don't need spacers for the blue wheel, but you need one spacer for the orange wheel and two for the pink.

  • Adjust the position on the tool's L-shaped guide using the included rectangle-shaped gauge. Insert the gauge within the guide and adjust its position until the gauge just touches the grinding wheel. Tighten the screws on the Dremel tool to secure the wheel.

  • Place the chainsaw in front of you with its motor to your right. This should put it in position for you to sharpen the teeth on the bar's far side. Power up the Dremel tool and wait for the grinding wheel to start spinning.

  • Insert the wheel into one tooth, lining up the guide's index line with the chainsaw bar; the index line runs along the guide's inside diagonal edge, meaning the wheel will be within the tooth at an angle. Apply light pressure on the tooth's cutting edge and stroke wheel in and out of the tooth a few times to sharpen it. Repeat this for all the teeth on this side of the bar.

  • Turn the saw over so the motor is on your left and use the wheel to sharpen the teeth on the bar's other side. This time, you need to use the guide's index line that nearly intersects with the guide's inside edge.
