It is the third sawmill in the Sawmax series and is called "Sawmax 02L" because it is a long version of the Sawmax 02. Both share the same components any sawmill has, but the L variant is unique for its ability to process wood with a length of up to 18.9 units.
Like its predecessor, the Sawmax 02L supports a maximum Plank Cross Section of X3 Y2.6 and can easily process logs up to 2.6 units in width (though it can process logs sightly bigger than that by using glitches like angle forcing to push the log inside, or up to 3 units in width if the player chops them into smaller chunks and inserts these chunks sideways into the sawmill).
The Sawmax 02L is fairly large in boxed form. It has the same color as the Sawmax 02, boxed and unboxed, but is longer than the Sawmax 02. It takes up as much space as a Val's All-Purpose Hauler's spawner.
Its box has a decal of the sawmill on its largest sides, and text spelling out "SAWMILL" on its top and bottom sides. The decal on the box, however, does not have green puffs and aura emitting inside it, unlike its unboxed form.
The Sawmax 02L was first discovered in the Roblox group called Beyond The Limits. It was added to the group models on June 1st, 2016. It was first thought to be released along with the Chop Saw, however, when the Chop Saw was released, there was no new sawmill to be found in the game.
On July 27th, 2017, the sawmill was secretly added in a morning update when Defaultio was repairing lost save slots. Its addition was not mentioned in the Changelog, however, was noted when he fixed the sawmill.
