WoodlandPRO PowerMAX bar and chain combinations are designed for professional users running chainsaws with 3/8" pitch saw chain. PowerMAX replaceable sprocket nose chainsaws bars are machined from a solid piece of heat treated silicon manganese alloy steel, making them incredibly rigid and wear resistant. 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.
