Circular sawmills allow lumber to be cut quickly and accurately. Portable sawmills are also used to produce specialty timber products. The popularity of circular sawmills has been on the decline since the invention of the Wood-Mizer portable band sawmill in 1982.
Circular sawmills provide operators with income by allowing them to saw lumber for customers as a mobile service. The thin blades of circular sawmills produce higher lumber yields that can benefit salvage logging operations. Circular sawmills also produce the large timbers required for post-and-beam framing techniques. Portable sawmills can be transported to a work location to produce lumber on site.
