Why Chainsaw Sharpening Matters
Proper chainsaw sharpening is essential for:
• Maintaining clean, efficient wood cutting
• Reducing strain on your saw
• Lowering fuel consumption
• Minimising vibration
• Improving cutting speed and productivity
A sharp chain cuts faster, runs smoother and reduces wear on your bar, sprocket and engine components.

145mm-22.23 hole centre 3.2mm thick

Always confirm disc diameter and arbor size before purchase.

- Tungsten carbide tips weld-fused onto every cutter, not hardened steel that rolls and dulls.
- Holds its edge up to 10 times longer between sharpening, so far fewer stops to sharpen.
- Eats dirty bark, sand and abrasive timber that blunts a standard chain in minutes.
- Australian family-run, flat $10 shipping, dispatched in 1 to 2 business days.
Can the tungsten carbide teeth be damaged?
Each tungsten carbide tip is weld-fused onto the cutter. Under normal cutting, the tungsten carbide is designed to last the life of the chain.
What damages the tungsten cutters is a blunt chain, over-forcing it into timber, or hitting steel, lead bullets, wire, rock or dirt, and that will wreck any chain.
Cut clean timber, keep the chain tensioned correctly, and keep the chain sharp. Used properly, the tungsten cutting teeth should outlast the drive links and the rest of the chain.

Why tungsten carbide?
Why tungsten carbide?
Tungsten carbide is one of the hardest cutting-tool materials going. We braze a tungsten carbide tip onto every cutter, so the edge holds up where a standard steel chain just rolls and dulls.
What that means on the saw: fewer stops, less sharpening, more wood through the bar per session. The chain body is German steel, high quality design for Australian hardwood.
10× longer edge life, what that actually means
10× longer edge life, what that actually means
A standard steel chain dulls after minimal work. A tungsten carbide chain stays sharp roughly 10× longer in the same conditions.
If you used to sharpen your chain after every fuel tank, now you can run a chain that lasts 10 times longer between sharpens.
Fits your saw?
Fits your saw?
Three specs to check:
Pitch, the spacing between drive links, stamped on your bar. 3/8" and .325" pitch are the most common for farm and forestry saws.
Gauge, the thickness of the drive link. Match your bar:
- .063" (1.6mm), suits most Stihl 3/8" setups (and .404 forestry saws).
- .058" (1.5mm), suits most Husqvarna 3/8" setups.
- .050" (1.3mm), low-profile chain for smaller / mid-range saws.
- .043" (1.1mm), low-profile chain for smaller saws.
Drive link count, total number of links. Depends on bar length.
Not sure? Use our Chain Finder, pick your saw model and it returns the exact pitch, gauge, and drive link count. Or send Aaron a photo of your bar stamping on 0431 183 421.
Sharpening, what you need to know
Sharpening, what you need to know
Tungsten carbide doesn't sharpen like standard steel chain. You'll sharpen these way less often, but when you do, use a diamond sharpening disc, a regular round file won't touch the carbide tip.
Signs it's time to sharpen: cuts are slowing down, you're applying more pressure than usual, or sawdust looks fine and powdery instead of chips.
For most users, expect 1–2 sharpenings a year of regular use, vs every few sessions for a standard chain.
Common questions
Common questions
How long does it last? Roughly 10× longer than standard steel chain in the same cutting conditions.
Can I sharpen it myself? Yes, but you need a diamond sharpening disc (not a regular round file).
Will it work on dirty timber? That's exactly what it's built for. Semi-chisel + carbide handles dirt, sand, and abrasive bark far better than full chisel chain.
Does it cut faster than standard chain? Standard chain is slightly faster on clean softwood. Carbide chain is faster on average in real cutting because it stays sharp, you spend the session cutting, not sharpening.
What kills it? Same things that kill any chain, dirt, rocks, fencing wire, nails in old logs, hitting steel. The chain is built for timber, not metal or stone.

Manufacturing defects: full replacement, just send a photo + order number. Reach out on 0431 183 421 or farmandacreco@gmail.com.
What's not covered: damage from hitting rocks, dirt, fencing wire, nails, or steel, that's wear-and-tear on any chain. Tungsten holds up better than standard, but it's not bulletproof against metal.

"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.

Great product
I am happy with the item
Started sharpening my chain cause it seemed dull. Tidied it up well, but found 4 chipped teeth! Not sure what happened if its operator error or faulty chain. Either way it's a mystery. Going to get another chain and pay CLOSE attention.
Thanks for the fair write-up Marzi. Four chipped teeth is worth a look rather than leaving it a mystery, so if you still have that chain, email us through the website and we will check it over.
One thing worth knowing for the next one. When you sharpen carbide, follow the tooth profile that is already there. Changing the angles or taking too much material off weakens the tooth and can show up as chipping later. Beyond that it is usually grit, wire or a stone under the log that does it.
