One drawback of this model is that the left and right sharpening angles are not even, which can stop your chainsaw from cutting well, making it seem blunt or making the cut crooked.


The consistency of sharpening angles is the main drawcard of all electric bench mounted chainsaw sharpeners. So much so that you’ll want to sharpen your chains frequently to make your chainsaw a cut above the rest in terms of efficiency. This model has a stronger motor than the Oregon 410-120 grinder, allowing you to use it more often without wearing out your machine.

Like the Oregon 410-120, there is a bit of a learning curve to set up and operate your machine. If you are a beginner, it might be easier to go for a manual sharpening method like the Stihl 2-in-1 Easy File or a Backridge File Kit.


  • Stronger motor for more frequent use
  • Easy to set up
  • Fast and accurate sharpening
  • Raker grinder included


  • Slight learning curve
  • Uneven right and left sharpening angles
