CAT 320 Bucket Teeth
Wear Parts Australia supplies Australian-designed aftermarket bucket teeth and related GET for fleets running CAT 320-class excavators — match the tooth series on your bucket (often CAT-style J350 on many 20 t diggers, but not guaranteed), then choose chisel, twin tiger, rock or abrasion profiles for the ground you dig. Order online where listed, or call 1300 135 307 (Mon–Fri 7.30am–4.30pm) with part numbers or photos for a firm fitment call before you buy.
Fitment follows the series on the bucket — not the machine model alone. We do not claim that every CAT 320, 320 GC or Next Gen uses the same teeth. Confirm series markings or send photos and we will point you to the right CAT-style line.
What CAT 320 bucket teeth does WPA supply?
WPA stocks CAT-style J-series teeth, adapters and pins used on many Australian excavator buckets. These are Australian-designed aftermarket parts — not genuine Caterpillar OEM. Catalogue prices show online where listed; fleet sets are quoted.
Common CAT-style series on 20 t excavators (J350 and others — verify)
Many Australian ~20 t CAT excavator buckets run J350-class GET. That is often true — not always. Some buckets on 320-class machines use other J-series patterns (for example J250, J300 or J400 lines exist in the broader CAT-style catalogue). Always read the stamp on the tooth, adapter or pin before ordering.
- Often first check: CAT-style J350 teeth, twin-strap adapters (e.g. for common lip thicknesses) and matching pins/retainers.
- Also available: related CAT-style J-series lines — confirm which series your bucket actually carries.
- Never assume: “fits all CAT 320s.” Series and lip thickness vary by bucket build.
Profiles — chisel, twin tiger, rock chisel, abrasion, heavy duty
| Profile | Typical use |
|---|---|
| Standard chisel | General digging and earthmoving — balanced cutting and wear. |
| Twin tiger | Breaking compacted faces and improving initial penetration in tough ground. |
| Rock chisel | Harder digging / rock and quarry-style duty where a heavier penetration tip helps. |
| Abrasion / heavy duty | High-wear ground where tip life and durability matter more than a sharp penetration shape. |
Choose profile for the ground you dig after you confirm series. More selection detail sits in our bucket teeth & adapters guide and the rock bucket teeth application page.
How to confirm fitment before you order
Model alone is not enough. A CAT 320-class machine can carry different bucket builds and tooth systems. Use the checklist below — or call us with photos.
Read the series on the tooth / adapter / pin
- Clean the side of a current tooth and look for the series stamp (e.g. J350-style markings).
- Check the adapter nose and pin/retainer for matching series cues.
- Note lip thickness and adapter strap style if you are replacing adapters as well as tips.
- If markings are worn off, measure pocket/pin and photograph the bucket lip — do not guess from “320” alone.
What to photograph for a same-day ID
- Side view of a tooth showing any stamped numbers or letters.
- Adapter / nose from the side and front.
- Pin and retainer (removed if safe to do so).
- Full bucket lip showing tooth count and spacer layout.
Email photos or describe them when you call 1300 135 307. We confirm before you order — we will not invent a fit from model name alone.

When to choose XP® on a CAT 320
XP® (Extreme Performance) is for production digging where abrasion, impact and downtime cost more than the cheapest tip on the page. On a 320-class machine that is often rock, quarry, sandy abrasion or high-hour civil work — not light landscaping duty.
See Who XP® is for and the XP® Range overview. Confirm series first; XP® still has to match the adapter system on your bucket.

FAQ — CAT 320 bucket teeth
Do all CAT 320 excavators use the same bucket teeth?
No. Fitment follows the tooth/adapter series on the bucket, not the machine model alone. Confirm series markings or send photos before ordering. We do not claim “fits all CAT 320 / 320 GC / Next Gen” buckets.
What series do CAT 320 buckets usually run?
Many Australian 20 t CAT excavator buckets use CAT-style J350 GET, but some buckets run other series. Verify the part on the machine — we will not guess from model alone.
Can I buy aftermarket CAT 320 teeth from WPA?
Yes. WPA supplies Australian-designed CAT-style teeth, adapters and pins. Catalogue prices show where listed; fleet sets are quoted. These are aftermarket parts suited to CAT-style systems — not genuine Caterpillar OEM.
Should I replace adapters with the teeth?
Replace adapters when the nose is worn, cracked or the pin fit is loose. New teeth on worn adapters shorten life and risk lost tips. Browse adapters and pins in the same series.
