I have had my DeWalt thickness planner for several years and really like how well it works. I never liked the noise and time it took plane down hardwoods especially oak and frankly, neither did my neighbors. I purchased a new helical cutter head from findbuytools.com and it has exceeded my expectations. It arrived quickly, was relatively easy to install and the results have been amazing. It’s at least 50% quieter and 4x faster. I love this improvement and wish I had known about it sooner.
