The Granberg MKIV's frame is milled from aircraft-grade aluminum, which resists flexing even when cutting full-width slabs from large logs. The result is a consistently flat surface that requires minimal planing afterward. This level of rigidity is rare among consumer chainsaw mills and directly translates to better lumber quality with less wasted material.
Cutting performance is most noticeable when the mill is matched to a powerful saw (50cc or larger) – the frame's rigidity translates into smooth kerfs and minimal blade binding. Less capable saws will bog down, so matching the mill to an appropriate power source is essential. Users running it with the right saw report uniform thickness across the entire board, even in dense hardwoods.
This mill is best suited for frequent millers and professionals who process multiple logs per session. Its 18-lb frame requires a 50cc+ chainsaw for best results, and the heavy build means it is not practical for small saws or quick, occasional cuts. If you mill infrequently or work with small-diameter logs, the smaller Granberg G777 may be a better fit.
The aluminum frame itself shows no signs of wear even after hundreds of slabs, though the zinc-plated steel guide bars are less forgiving under extreme loads. Occasional replacements are possible for high-volume operators. At a premium price, the MKIV costs more than many competitors, but the US-made materials and precise fit mean fewer adjustments and longer service life for serious millers.
Consider using a cant hook or log roller to minimize lifting strain – the mill's weight adds to the effort of positioning.
Bottom line: For millers with a powerful saw who demand consistent, flat slabs, the Granberg MKIV is the tool that delivers without compromise.
