A high-performance sawmill that can be stored right in your garage.

Move it. Mill it. Stow it. The Frontier OS18 Sawmill is the first high-performance portable sawmill designed to be set up in minutes and stored right in your garage or workshop.

Built with Frontier’s commitment to quality and integrity for truly reliable operation, the OS18 is fully capable of cutting sizable 18” logs and boards up to 16” wide, in half the time and with two-thirds less waste than a chainsaw mill.

Designed with patented innovations, including the Auto-Locking Sawhead and EZ Blade Tension, you get more done, in less time, with less space. The detachable sawhead with moving kit and two-piece precision track system lets you easily wheel the sawmill around and allows for compact storage in a shed or garage. Customize your mill with optional leveling legs, log loading ramps, Auto Blade Lube system, and track extensions so you can cut logs of any length.

Designed with convenience in mind, the OS18 can be easily assembled, disassembled, moved, and stored. You can wheel the saw head to your desired location, similar to moving a dolly cart. The track sections easily detach and can even be hung up. With its ultra-compact storage footprint and the included moving kit, it's ready to roll to wherever and whenever you need it.

With an ultra narrow kerf blade, the OS18 cut width is 2/3 smaller and far less wasteful than a chainsaw mill, maximizing the yield from every log. Chainsaw mills are slow and not ideal for large production. They waste a lot of wood by turning into into sawdust due to their large kerf size.

The patented infinitely-adjustable auto-locking sawhead offers precise depth-of-cut control, simplifying your cutting process and saving time. One turn of the crank equals 1 inch of blade height adjustment.

The patented EZ Blade Tension systems allows for frustration-free blades changes by preserving critical band wheel alignment when you tension the blade. When blade tensioning is easy your band blade changes are fast, allowing for more time milling.

The detachable sawhead with moving kit and two-piece precision track system lets you easily wheel the sawmill around your property and allows for compact storage in a shed or garage. The track sections can be hung up and the detachable sawhead footprint is only 58" x 43"

The log chock ensures large logs remain secure during milling on the OS18 sawmill. Simply set the log chock on a cross-bunk, slide it firmly against the log, and clamp. Your standard Frontier OS18 sawmill comes with one log chock kit. Add an additional log chock kit to support longer logs.

The Log-dog/log-rest system securely holds a log on the sawmill log bed. The log-dog uses a screw-dog system to firmly hold logs or cants while cutting. The patented quick-set bar takes the guesswork out of clamping your cant low and clear of the blade’s path, so you can easily make your last cut. The sturdy log-rest allows for squared cuts and folds down for convenient storage when using the cant stops.


With every Frontier sawmill, you receive a one-year consumer warranty. We will repair or replace, at our discretion, any part returned to us and found to be defective through manufacturing within the first year of the original purchaser’s ownership (except consumable items like belts, blades, bearings & clutch). The engine is covered under warranty directly with the engine manufacturer (two years by Briggs and three years with by Kohler). We back that up with a 30-day money-back guarantee. If your Frontier doesn’t do everything we say, simply return it to us within 30 days and receive a refund (shipping not included)*.*Not including used blades, damaged parts or restocking fees.

The sawhead is pre-assembled at the factory, and thanks to the fully illustrated step-by-step manual with exploded illustrations, diagrams, and photographs, the rest can usually be put together in a single day or less. You'll only need a few basic tools, including combination and Allen wrenches, a ratchet with SAE and SI sockets, an adjustable wrench, a Phillips screwdriver, a drill, lubricating and engine oils, and a grease gun. Regardless of your skill level, Frontier Sawmills are designed to be user-friendly and easy to operate. We also provide toll-free support from the moment your Frontier Sawmill arrives, through your first cuts, and beyond.

You have the option to enhance your setup with available log loading systems designed for the Frontier OS18. This includes a log loading ramp package with spring-loaded rollback assist cleats to help roll logs up onto the mill bed. Additionally, a traditional ramp with grips is also available. A peavey is an indispensable tool for moving logs to the mill and is useful for gripping and leveraging logs during the loading process.

Standard, the OS18 band sawmill log bed is 10 feet long (3.29 m), which allows you to makes cuts up to 8 ft 1 in (2.4 m) in length. To saw longer material, you can add optional 5 ft (1.5 m) log deck extensions. You can add multiple extensions to cut logs of any length.

The Moving Kit for the OS18 includes two solid wheels and a sturdy handle grip that attach directly to the saw head. This kit is a standard feature and allows you to remove the saw head from the track and wheel it around, similar to using a dolly cart. The OS18 sawmill was designed with convenience in mind and can be easily assembled, disassembled, and stored. The track disconnects into two pieces, making it easy to move by hand and even hang on hooks. If desired, you can remove the Moving Kit wheels and handle to use the OS18 with the optional levelling legs at a more comfortable working height.
