DeWalt chainsaws suffer from common problems, despite being a reputable brand. The DeWalt line of chainsaws has its strengths and weaknesses, with some models being highly recommended, such as the 60V MAX 20 Brushless cordless chainsaw, while others, like the 20V MAX XR chainsaw, are best avoided.
Most DeWalt chainsaw issues are related to oil, stemming from design flaws. Currently, DeWalt offers entirely electric models, including a few corded models, like the DeWalt 18-inch corded chainsaw, but the majority are battery-operated.
