Diamond chainsaw file — for sharpening carbide chains a normal file won't touch.
Carbide-tipped chains hold an edge for ages, but when they finally dull a standard steel file won't cut them — the carbide is harder than the file. That's what a diamond file is for. The diamond grit grinds the carbide back to a clean edge, so you get more life out of an expensive chain instead of binning it.
Handy to keep in the kit if you run carbide chain for dirty, abrasive or storm-damaged timber where a normal chain blunts fast.
Pick the size to match your chain:
- 4mm — smaller pitch chains .325 and 3/8LP .043-050
- 5mm — larger pitch chains 3/8
Not sure which one you need? Send us a photo of your chain or the markings on your bar and we'll point you the right way.

"Unreal family business. Seeing a small family go out and have a go gets my vote every day."
"I couldn't be happier with the service and products I've received from Farm & Acre Co. I've purchased both cattle ear tags and chainsaw chains, and the quality of everything has been outstanding. Their customer service is second to none—friendly, knowledgeable, and genuinely helpful from start to finish. Pricing is extremely competitive, especially considering the quality of the products, and the turnaround time was impressively fast. My order arrived quickly and exactly as promised. It's rare these days to find a business that delivers the best service, best products, and great value all at once, but Farm & Acre Co does exactly that. In my opinion, they're one of the best farm supply businesses in Australia, and I wouldn't hesitate to recommend them to anyone in the rural or agricultural industry."
