HM122 Portable Sawmill

Powered by a reliable 7.0 HP or 9.5 HP 4-cycle Kohler gas/petrol engine. The HM122 features a slant cylinder design, with a cast iron cylinder bore and an overhead valve for easy access. The Quad-Clean 4-stage air filtration system ensures only clean air enters the engine for maximum power and life of the engine. Attached to the engine is an industrial centrifugal clutch system for easy gas-and-go operation. Backed by a 3-year Kohler commercial warranty.

Our heavy-duty 4 post head design is reinforced with a back beam and welded top tubular crossbeam. The assembly is anchored between our precision laser-cut carriage side plates, to provide exceptional rigidity, and ensure smooth, accurate cuts.

Every one of our sawmills features a gas and go auto lube system. This means the throttle handle engages the engine RPM, saw blade and patented auto lube system simultaneously. This system makes the process of cutting lumber quick and efficient and reduces the number of steps required by the operator.

Our sawmills are equipped with a weather-resistant aluminum lubricant tank, ensuring long-lasting performance in the most adverse conditions. The tank's needle valve allows precise control over the flow to the auto lube valve, enabling fine-tuning as needed.

We’ve designed a unique constant-pressure U-bushing that facilitates a positive connection between the sawhead and the carriage posts while allowing the sawhead to move up and down smoothly. The U-bushings are constructed from glass-filled nylon, giving them a long service life.

The RapidChange® blade system is exclusive to Woodland Mills. RapidChange® is a tool-less approach for changing blades quickly that reduces the need for blade tracking adjustments between blade changes. Stacked Belleville washers act as a shock absorber for the blade while giving consistent blade tension in all temperatures, ensuring less stress on the blades.

The saw's carriage wheels have a dual race bearing. This provides the best connection between the rolling wheel and the track surface, to ensure stability from the wheels to the track to the sawhead. The radius profile in the groove and the square-topped tracks are designed to wear together to make a matched set over time. To keep the track free from debris, stainless steel wire sweepers clean the track while in use.

To reduce your assembly time, we carefully pre-assemble key components of the sawhead. Having the advantage of pre-assembled parts help you get up and running faster, saving you valuable time.

Two magnetic scales provide multiple preset board-thickness settings with built-in kerf allowances for consistent, accurate cuts ranging from 3/4" to 4" thick. The scales help you track blade height off the deck for precise board and cant sizing. Made from durable, UV-protected vinyl with strong magnetic backing for a secure hold and clear visibility in all conditions.

Our blade guards are built with durable, powder-coated metal for resilience and longevity. For added convenience during sawhead maintenance or blade changes, the guards are side hinged, allowing them to easily move out of the way and provide unobstructed access.

Our adjustable throttle assembly offers complete customization for individual needs. You can position both the throttle and push handle according to your preference based on track height, ensuring a comfortable operating experience.

Our mills are designed to cut logs up to 10' 5" (3.1 m) long using the standard track configuration. You can unlock unlimited length potential by adding optional 6' 5" (1.95 m) or 2' 6" (0.76 m) track extensions. These extensions come with an extra log clamp assembly, log support, and required bunks, allowing you to customize the cutting length to your specific requirements.

Tailor your sawmill to suit your specific needs and maximize efficiency with our optional accessories. Choose from a comprehensive lineup of equipment, including a lapsiding attachment for added versatility, and a selection of log handling tools. Every one of our accessories is designed to make your job easier and expand the capabilities of your equipment.

The HM122 uses rigid 2 3/8″ x 2.5″ (6 cm x 6 cm) L-rails with precision-machined tops to support smooth, accurate sawhead travel. These rails are cross supported with heavy-duty 2 3/8″ x 4 3/4″ (6 cm x 12 cm) rectangular log bunks. These cross supports ensure the weight of the log is dispersed over a large bearing surface to avoid marking the log with indentation and provide additional rigidity to the track system.

The track itself consists of two 6’ 5” (1.95 m) sections allowing for 10’ 5” (3.1 m) log lengths. Additional 6’ 5” (1.95 m) or 2' 6" (0.76 m) tracks can be attached to accommodate logs of any length.

The HM122 features a simple screw-style log clamp that securely holds the log in place during milling. It also comes with two short log supports and two longer ones to help keep logs steady and secure while milling. A set of short and long log supports is also included, giving you flexible height options based on your mounting height and the size of material you’re cutting. Together, these components provide stable, reliable log control for clean, consistent cuts.

Balanced using a high-speed machining process, our bandwheels ensure optimal consistency, minimizing vibrations and maximizing efficiency. Our bandwheels deliver cleaner, more accurate cuts with reduced blade deflection and increased durability.

The HM122 utilizes 1.25″ x 125″ x 0.042″ (32 mm x 3175 mm x 1.0 mm) hardened tipped blades which are available through Woodland Mills. Blade kerf is kept to a minimum at just 0.080″ (2 mm) to maximize the most amount of lumber per log.

The HM122 can cut 22" (55 cm) diameter logs and mill live edge boards up to 20” (51 cm) wide. Cut logs 10’ 4” (3.1 m) long with the standard track configuration, or unlock unlimited length potential with optional 6’ 5” (1.95 m) track extensions. The HM122 can skim veneers as thin as 1/16" (2 mm), and cut within 1" (25 mm) of the deck, ensuring you maximize your usable board foot output.
