The Oregon 584408 18" SpeedCut chain saw bar and chain combo includes a 95TXL chain saw chain and chain saw bar. SpeedCut's narrow kerf design allows for faster cuts since less wood is displaced. Combining the narrow kerf 95TXL saw chain with the narrow kerf guide bar results in faster and better cutting for mid-size chain saws. The 95TXL chain saw chain has a reshaped cutting surface and narrow kerf design which means that you get a faster and easier cut. The chain saw chain has a sharper, more durable cutting edge. The chain is easier to sharpen since the cutting surface is matched to the file and there are more indicators to help you spot the recommended filing angles. Aerospace bonding technology makes the bar stiffer and stronger. A redesigned nose and harder bar rails make the chain saw bar last longer. LubriTec keeps guide bar rails, chain drive link and chain rivet joints oiled for less wear and faster life. This combo works with certain Craftsman, Husqvarna, Jonsered, McCulloch, Solo and Troy-Bilt chain saw models. Check the fit guide to see if this chain saw bar and chain combo works with your saw.
