Simply the most efficient, light weight and reliable solution to mill almost anything, almost anywhere! Built from aluminium and stainless steel to last a lifetime in all weather, the Peterson WPF + DWS Combination is the ultimate portable sawmill solution.


Selective Milling

Not only are these mills worth their weight in gold alone.. combined, they offer the most versatile cutting options on the martket when run on the same track system – allowing you to mill dimensional timber and slabs from the same log – all without moving it!

Unbeatable Quality and Durability

Manufactured using high quality, hand polished stainless steel and aluminum, providing a virtually rust free sawmill. Using stronger, lighter materials also means the mills are robust in performance, and most importantly – have long-term durability in even the harshest conditions.

Stability and Accuracy in Every Cut

The Peterson Hi/Lo track set up comes standard with the WPF + DWS Combo and can be extended to any length.
The Hi/Lo set-up provides the optimum structural design, where the two opposite corners of the sawmill are braced, providing the best stability, accuracy and safety.

The Peterson Edge

With every Peterson Sawmill you get over 30 years of innovation, quality and high performing features

Accurate, Safe Sizing

All Peterson Portable Sawmills left/right sizing system is run by chain and sprocket, with a turning handle and lock. So that means it will only move when you unlock it, and you can position the sizing very accurately to within 1mm. No slippage, and top accuracy for every board.

Durable, Low Maintenance Blades

Our Peterson Blades last for 2-6 years with normal use and maintenance. However, some swing blade sawmill owners have been using the same blades for over 10 years! To decrease downtime, the Peterson blade can be sharpened while it is still on the mill; in less than 10 minutes, and without having to remove any guards.

Elevated Engines with Cyclonic Air Filters

We mount our sawmill engines higher than other manufacturers to ensure the air filter intake is further away from the sawdust output, helping prevent sawdust build up and overheating of the motor. Specifying Cyclonic Air Filters to separate clean air from debris and liquids also helps to improve the lifespan of your engine, with the added bonus that these filters last up to three times longer than standard duty filters.

Built to Last

All Peterson Sawmills are manufactured in our Rotorua, New Zealand factory and come standard with a 24-month return-to-factory warranty on the frame which includes all bed framing, track and carriage material manufactured by Petersons Global Sales Limited. We also offer an extended five-year frame warranty. This option can be included at time of purchase.
