Dremel Chainsaw Sharpening Instructions


Dremel rotary tools have many attachments for grinding, cutting and polishing items. The Dremel chainsaw sharpening attachment kit allows do-it-yourself sharpening of your chainsaw blades. You should always keep your chainsaw blades sharp. Dull blades will seize, pulling the chain off the bar. Dull blades can also bounce off wood instead of biting into it, kicking the chainsaw back and possibly injuring you.

Things You'll Need

  • Measuring tape
  • Screwdriver
  • Work gloves
  • Safety glasses
  • Dremel chainsaw sharpening attachment
  • Place the chainsaw on a flat, level surface like a table or a workbench.

  • Measure the distance between the center of one chain rivet to the center of the third consecutive rivet with a measuring tape. Divide this number by two to determine the pitch of your chain.

  • Screw the guide and spacers for the chain pitch to the guide ring on the sharpening attachment. Place the correct number of spacers on the ring with the screw holes aligned in the spacers and guide ring. For a 3/8-inch pitch use both spacers; for a 0.325-inch pitch use one spacer; use no spacers for a 1/4-inch pitch. Set the guide plate on top of the spacers. Insert the two screws in the saw sharpening kit into the two holes on top of the guide plate and through the spacers and guide ring. Tighten the screws clockwise with a screwdriver.

  • Insert the correct sharpening stone into the Dremel tool with 1/4-inch of the shank of the stone between the stone and the chuck head. Use the pink stone for a 3/8-inch pitch, the orange stone for a 0.325-inch pitch and the blue stone for a 1/4-inch pitch.Tighten the chuck cap with the Dremel wrench in a clockwise direction.

  • Insert the end of the Dremel tool into the round ring of the guide ring. Screw the sharpening guide onto the Dremel tool in a clockwise direction. Put work gloves and safety glasses on. Stand to one side of the chain. Turn the Dremel tool on and set the guide flat against the chain side. Insert the grinding stone into one tooth and make three to four passes over the tooth to sharpen it. Count the passes and sharpen each tooth the same amount. Continue sharpening all the teeth on this side of the chain; turn the chair by hand to advance it. Repeat procedure on the opposite side of the chain.

Tips & Warnings

  • Most chainsaw bars have their pitch printed on them, but the printing can become hard to read if the chainsaw has been used for more than a few hours.
  • An adjustable wrench will tighten the chuck cap on a Dremel tool if you have misplaced the wrench that was included with the tool.
  • Dremel chainsaw sharpening kits include instructions on assembly of the guide and the appropriate color-coded grinding stones for each size pitch of your chainsaw chain.
