HM122 Portable Sawmill (2024)

The Woodland Mills HM122 Portable Sawmill is designed for hobby sawyers looking for an economical solution to mill lumber. The HM122 can cut 22” (55cm) diameter logs, producing boards up to 20” (51cm) wide and up to 10’ 4” (3.1m) in length. Constructed using a 4-post head design with a tubular back beam that provides the ultimate rigidity, ensuring smooth and accurate cuts. The head moves up and down along galvanized steel posts via an easy to turn hand crank system. Powered by a reliable 7.0 HP or 9.5 HP 4-cycle Kohler gas engine. The HM122 is loaded with new and innovative features like the automatic blade lubricant system that activates when the throttle is engaged and the RapidChange™ blade system for quick and tool-less blade changes. The highly reviewed HM122 continues to be the best-valued sawmill in its class.

The HM122 can cut 22″ (55cm) diameter logs and mill live edge boards at up to 20″ (51cm) wide. Cut logs 10’ 4” (3.1m) long with the standard track configuration or unlock unlimited length potential with optional 6’ 5” (1.95m) track extensions. It can also skim veneers as thin as 1/16″ (1.6mm). The HM122 will cut within 1″ (25mm) of the deck ensuring that you maximize your usable board foot output.

Powered by a reliable 7.0HP or 9.5HP 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.

The HM122 sawmill head rolls along a rigid 2 3/8″ x 2.5″ (6cm x 6cm) machined “L” channel which is cross supported with heavy-duty 2 3/8″ x 4 3/4″ (6cm x 12cm) rectangle 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 features an easy to use screw style log clamp to securely hold the log while milling and consists of two 6’ 5” (1.95m) sections allowing for 10’ 4” (3.1m) log lengths. Additional 6’ 5” (1.95m) tracks may be attached to accommodate logs of any length. The track comes with 12 levelling legs with up to 4” (10cm) of adjustment.

The throttle handle engages the engine RPM, saw blade and 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. The throttle handle position can also be adjusted for comfort depending on track height.

Exclusive to Woodland Mills is the RapidChange™ blade system. This is a tool-less approach for changing blades quickly and reduces the need for blade tracking adjustments between blade changes. A stack of Belleville washers act as a shock absorber for the blade while giving consistent blade tension in all temperatures ensuring less stress on your blades.

The HM122 utilizes 1.25″ x 125″ x 0.042″ (32mm x 3.175m x 1.0mm) hardened tipped blades which are available through Woodland Mills. Blade kerf is kept to a minimum at just .080″ (2mm) to maximize the most amount of lumber per log.
