Granberg Chainsaw Sharpener G106B — Bar-Mounted File-N-Joint Guide for Consistent Angled Sharpening, Durable Metal Construction

The Granberg G106B File-N-Joint is a bar-mounted chainsaw sharpening guide that secures to your saw bar to produce consistent, correctly-angled file strokes for fast, repeatable tooth sharpening.

If you want cleaner, safer cuts and longer-lived chains without guessing angles, the Granberg G106B offers a simple, durable bar-mounted guide that keeps your round file aligned with the chain's factory bevels. It attaches to the chainsaw bar and indexes each tooth so sharpening is uniform from tooth to tooth, saving time and reducing wear from uneven filing. Built for field or shop use, the G106B is lightweight, metal-constructed, and designed to work with standard round files and common chain pitches.

How does the G106B keep each tooth sharpened the same way?

The G106B clamps to the bar and uses a keyed guide that indexes the file at the proper angle for every tooth, removing guesswork. With the guide fixed in place, you push the file across each cutter using the same motion and pressure, producing repeatable bevels.

• Bar-mounted fixture ensures consistent file angle across the entire chain
• Works with standard round files sized to your chain pitch
• Clamping hardware secures guide to avoid slippage during use
• Durable metal construction tolerates field conditions

What chain types and file sizes does it support?

The G106B is compatible with most common chainsaw chain pitches that use a round file — such as .325" and 3/8" where appropriate files are available. Confirm your chain pitch and cutter specifications, then select the matching round file to use with the guide for correct contact and results.

• Fits chains that accept round-file sharpening
• Use the round file size recommended by your chain manufacturer
• Not for carbide-tipped or specialty cutters that require different sharpening tools
• Simple compatibility check: match file diameter to cutter groove width

How easy is it to mount and use during a job?

Mounting takes just a few minutes: align the guide on the bar, secure the clamp, and set the file guide to the chain. Because the device is compact and attaches to the bar, you can sharpen in the field between cuts without removing the chain in many situations, speeding maintenance on the job site.

• Quick clamp-on installation with basic hand tools
• Portable and lightweight for mobile sharpening needs
• Allows consistent, rapid filing between cutting sessions
• No electricity or batteries — purely mechanical operation

What maintenance and safety practices should I follow?

Keep the guide clean and free of sawdust, periodically check the clamp for tightness, and replace worn components as needed. Always wear cut-resistant gloves and eye protection while filing, and follow your chainsaw manufacturer's safety guidelines when working with the bar mounted device.

• Wipe debris from guide after use and lightly oil moving parts
• Inspect clamp screws for tightness before each sharpening session
• Use recommended file size and maintain correct filing strokes
• Follow personal protective equipment (PPE) guidance for chainsaw work

Who is this for? The Granberg G106B File-N-Joint is ideal for loggers, arborists, property owners, and DIY users who prefer a simple, reliable mechanical guide for chainsaw maintenance. If you do routine cutting and want uniform tooth geometry without expensive electronic sharpeners, this bar-mounted system gives predictable results with minimal setup. It fits into toolkits for those who need to sharpen on-site or in a small shop and value consistent filing, durability, and straightforward operation.
