I grabbed this too keep as a spare in truck. I've had this style 'Raker'/drag/depth gauge before. Personal favorite is the simple flat plate multi-gauge tool husky makes, but any gauge us better then none when your out on the job.. Im a full-time tree guy. can't beat the price of this gauge & flat file. The file is a good file, stays clean, removes saw'chain rakers in a pass or too. Another thing about this gauge, it's simple too use. Good easy instructions on back of package, so anybody on my crew can use it. (Now they just need too learn how too sharpen chain by hand with a round file). Good thing about this,any..raker gauge, it keeps both sides of the rakers even, depending height of actual tooth, since it set across the 2x cutting teeth "working edge' of teeth in front of and behind, the one your hitting. Your best too skip every other tooth, (keep too one side ie: right side, then switch too opposite side, ie: left side, you'll feel the file removing material smoother, easy,no squeek noise.. that said just changing angles of file or/and directly, 'against/with grain, will stop that noise too. check youtube #buckinbillyray & others for saw sharpening tips.. But it's a great lill' kit for giving a good pretty darn even precise gauge' over the rakers/drags. And it's fairly fast an easy too get a hang of. First day I had gauge. had a chain on a 562xp husky, starting too cut on angle. This gauge will help make sure it gets you back cutting strait, cutting-removing material all even, effeciecnt, smooth. Great tool for any saw owner. Set @ .25" is avg recommended height for rakers vs. cutting edge. I use too like them at more, ore less, depending saw power. Chain type, size.. tree species. Dry, wet. Etc. Most pro's adjust there chains with files accordingly. But this gauge set at .25" thou, is about perfect for regular 3/8"/.375 semi/full chisel chains. Only complaint about this style gauge, is the file slides across it, an after a few chains, the romoval of its own material will start too increase the amount of material your removing off if the rakers. But it's better then no gauge at all. And the file holds up fine.
