The New Laguna 20” Planer is best in class for many reasons. The ShearTecII Cutter Head is a 6 row system; most planers offer only 4 or less. This means the ShearTecII will last longer. 4 sided German carbide knives give a better finish, while deep gullets & thicker knives allow for better removal. Another benefit with our planers is the noise level ; customers cannot believe how ULTRA quiet they run!Digital readout is standard, something you usually have to pay extra for with other brands.Extensions are standard. Built -in wheel system also standard.
