Remember when sharpening your saw chains didn't take forever? Get your grind on with the WEN Chainsaw Sharpening Guide for Rotary Tools. This handy accessory transforms your WEN or Dremel rotary tool into a chain-sharpening station, perfect for resuscitating dull saw chains from your chainsaw or pole saw. With optional sharpening angles of 25, 30, or 35 degrees, as well as three diamond-grit grinding bits, you'll be able to tackle a wide range of saw chains (1/4, 3/8, 3/8 low profile, and 0.325-inch pitches). Compatible with most WEN and Dremel rotary tools, as well as the majority of rotary tools on the market with an M19-2.0 accessory attachment thread. This kit includes the sharpeningguide, three grinding bits (5/32, 7/32, and 3/16-inch diameters, all with standard 1/8-inch shanks), and two 3/8-inch wrenches. Remember when you spent more time cutting firewood than sharpening your saw chain? Remember WEN.
