WoodlandPRO TimberMAX bar and chain combinations are the perfect match for semi-professional and professional users running chainsaws with 3/8" pitch saw chain. TimberMAX chainsaws bars have a wide contour, making them stout enough for professional use, yet the lightness of the core makes them easier on your back. We match these bars with a loop of fast cutting WoodlandPRO 30RC chisel chain. WoodlandPRO 30RC is our best selling chainsaw chain, and for good reason. The razor sharp chisel cutters cut most woods like a hot knife through butter, and it's easy to sharpen with a 7/32" file or 3/16" grinding wheel once it gets dull.
