Sharpening chains can sometimes feel like harder work than the cutting itself. That’s exactly why we developed the RCS28 PRO Chainsaw Sharpener. It’s built to make chain sharpening quick, simple and virtually hands-off — ideal if you’re getting through multiple chains in a single day.
The RCS28 PRO Chainsaw Sharpener is a fully automatic sharpener. Once you’ve set it up to suit your chain, the mechanical actuating head automatically alternates between left- and right-hand cutters, as well as the depth gauges (rakers). There’s no need to remove the chain or manually swing the grinding head during the process. It’s a true one-touch solution that sharpens your chain from start to finish. When needed, simply follow up with the dedicated depth gauge grinding cycle.
With a sharpening cycle that takes just a few minutes, the RCS28 PRO quickly brings tired chains back to life, delivering consistent, accurate results on every cutter.
Powered by a 12V battery for maximum portability, the RCS28 PRO Chainsaw Sharpener keeps your chains sharp wherever the job takes you. Whether you’re cutting firewood, clearing tracks, managing property, or working on tough job sites, the RCS28 PRO delivers reliable, factory-level sharpening performance — anywhere in Australia.
