Granberg G555B Edging Mill for 16–36" Chainsaw Bars with 12 ft V-rail — Aluminum guide, Zinc-plated hardware

The Granberg G555B Edging Mill is a portable vertical chainsaw guide that converts a chainsaw into a mill for straight, squared cuts on logs using 16–36" bars and included 12 foot V-rail.

Turn a compatible chainsaw into a reliable milling setup with the Granberg G555B. Built from aircraft-grade aluminum extrusion and zinc-plated steel, this edging mill attaches to solid-steel bars from 16 to 36 inches to guide vertical cuts and help you produce dimensioned lumber, squared timbers, or clean milling faces. The package includes 12 feet of V-rail, fastening hardware, a polycarbonate safety guard, and access to Granberg’s support resources.

How does the G555B help produce straight, even vertical cuts?

The G555B locks your chainsaw bar into a fixed plane alongside a V-rail, keeping the chain tracking true while you move the tool along the log. This fixed guide reduces wandering and human error, so each pass removes a consistent thickness and delivers repeatable results.

• Uses a 12-foot V-rail to stabilize the mill across the log surface
• Works with 16"–36" solid-steel chainsaw bars for broad cut options
• Polycarbonate guard improves visibility and adds protection

What chainsaw and bar requirements do I need to use it safely?

To operate the G555B you must use a chainsaw equipped with a solid-steel bar (laminate bars are not compatible). Granberg recommends at least a 50cc engine to power milling tasks; there is no specified maximum engine size, but proper handling and chain tensioning are essential for safe operation.

• Requires a solid-steel chainsaw bar, 16" to 36" in length
• Recommended minimum chainsaw size: roughly 50cc for milling loads
• Ensure correct chain tension, sharp cutters, and routine maintenance

What materials and build features increase durability and accuracy?

The G555B’s main beam is machined from USA-made aerospace-grade aluminum extrusion for straightness and low weight, while zinc-plated steel components resist corrosion and wear. The included hardware and forming nails let you fasten rails and set-up points to timber for repeatable, accurate passes.

• Aerospace aluminum extrusion keeps the guide rigid yet lightweight
• Zinc-plated steel parts withstand outdoor exposure and repeated use
• Includes wood screws and forming nails to secure the V-rail precisely

How do I set it up and where can I get help if I’m unsure?

Granberg supplies the V-rail, fastening hardware, and a polycarbonate guard so you can assemble and place the guide quickly. For step-by-step instruction and troubleshooting, Granberg provides how-to videos and customer support from experienced users who can advise on setup, milling technique, and safety precautions.

• Packaged with 12 ft of V-rail, screws, and forming nails for installation
• Polycarbonate guard included to protect the operator and enhance visibility
• Granberg customer support and instructional videos available online

Who this is for: The Granberg G555B is designed for loggers, arborists, homestead builders, and serious hobbyist woodworkers who want a portable solution to square logs and cut dimensional lumber without a dedicated sawmill. It’s ideal when you need on-site milling, want to salvage timber, or prefer to process wood with equipment you already own, provided you use a compatible solid-steel bar and follow safe milling practices.
