Sharing the same magnesium alloy crankcase and packed into the same compact frame as the 455CSX, the 515CSX offers a longer 20 oregon guide bar and even more powerful 50.9cc engine. Despite its power, the 515CSX is surprisingly easy to handle, thanks to its optimised balance, weight saving features and ergonomic soft grip handles. Perfect for homeowners, landowners and farmers looking for a reliable powerful saw.
