Sharpen any chainsaw chain on the bar in 60 seconds without removing it, delivering a refreshed edge that cuts like new.
Inside, the burr uses electroplated industrial diamond grit bonded to a hardened steel shank to re-cut the tooth shape. It seats in the cutter’s gullet and faithfully traces the factory angle in a single short pass, capable of cutting through hardened chain steel without skating. Each tooth receives a 3–5 second treatment, so a standard 16-inch chain is effectively sharpened in about a minute.
It snaps into any standard drill with a 1/4" shank—cordless or corded—without needing a special base or clamps, and you don’t have to detach the chain. You guide the angle while the drill spins and the diamond burr does the cutting.
Three sizes cover most saws: 0.16" for 1/4" pitch pruning chains, 0.19" for.325" and 3/8" low-profile homeowner chains, and 0.22" for 3/8" full and.404" pro chains. These sizes fit popular brands like Stihl, Husqvarna, Echo, Ryobi, and Greenworks.
Why this approach outperforms a round file: a fixed-speed drill maintains steady power, the burr sits in the groove, and it simply traces the existing tooth profile. Each tooth is treated for 3–5 seconds, and a single pass can bring a chain back to factory sharpness in under a minute. Diamond grit lasts far longer than carbon steel files, so the same burr serves dozens of sharpenings.
Professional filers who once relied on hand tools found it transforms their workflow; homeowners who previously paid for shop sharpenings discover significant savings by sharpening between fuel stops. The setup pays for itself after sharpening just a couple of chains.
What a sharp chain feels like again: it throws clean, square chips across the work area rather than dust, and you can skip trips to the shop by doing it right at the tailgate. The diamond burr resists wear far longer than a traditional file, making it capable of many sharpenings.
Sharpen in three steps. Step 1: choose the burr size to match your chain pitch—0.19" for most homeowner saws, 0.22" for larger pro chains, 0.16" for pruning. Step 2: lock the burr in your drill chuck and rest the bar on a stable surface so the chain stays put. Step 3: run the burr along each tooth at the existing angle for 3–5 seconds, moving to the next tooth. Complete the full chain in under a minute.
Package includes 6 burrs total—2 of each size.
