Rock, demolition and frost
Rock chisel teeth carry extra material at the tip and last longest in abrasive ground. Pair them with side cutters so the bucket corners don't wear through first.

Excavator Bucket Teeth and Wear Parts: Match the Tooth System, Then Pick the Style
Replacement bucket teeth, adapters, tooth pins and retainers, side cutters, bucket pins, shims and hydraulic hammer chisels. Every tooth is listed by its part number and style, so you can match what is on your bucket today. Stocked in Miami, Florida and shipped nationwide.
What Wear Parts Does an Excavator Bucket Use
A bucket's cutting edge is protected by a row of adapters welded or bolted to the lip, and each adapter carries a replaceable bucket tooth held on by a tooth pin and a retainer. The tooth takes the wear so the adapter and the bucket lip don't. Side cutters protect the corners and widen the cut, and a side bar protector covers the bucket's side plates.
Where the bucket meets the machine, bucket pins and shims take up the slack that builds between the ears and the stick. JMA also stocks adapters and covers for rebuilding a worn lip, and hydraulic hammer chisels for breakers.
How to Match a Replacement Tooth
Start with the tooth system, not the bucket brand. Most teeth have a part number cast on the side; read it, or measure the adapter nose and pin hole and send us a photo. Caterpillar-style J-series teeth are numbered by size: 1U3202 is the J200 size, 1U3252 the J250, 1U3352 the J350 and 1U3452 the J450. Hensley-style X156 and ESCO-style V23 teeth only fit their own adapters, so a Cat-style tooth will not go on an ESCO-style nose.
| Style | Best for | Example part numbers |
|---|---|---|
| Standard | General digging and loading in mixed soil | 1U3202, 1U3252 |
| Rock chisel (RC) | Rock, frost and compacted ground; long wear life | 1U3202RC, 1U3452RC, 9W8452, 475-5473, 1000.3 |
| Single tiger (TL) | Hard clay and trenching; one sharp point penetrates | 1U3202TL, X156TL |
| Twin tiger (WT / WTL) | Trench corners, frozen ground and rock seams | 1U3202WT, 1U3252WT, 1U3352WT, 1U3452WTL, 135-9408, X156WTL |
| Flare (F) | Grading, loading and a clean, flat trench bottom | 1U3202F, 1U3252F, X156F |
| Long and penetration tip | Loose to medium material where fast penetration matters | X156L, 9N4352, 1U3209, 9W8459 |
| Ripper | Ripper shanks on dozers and ripper attachments | 4T5502, 9W2451 |
Cat-style part numbers are Caterpillar-style replacements; Hensley-style and ESCO-style teeth fit their own adapter systems only.
Once the system and size are known, pick the style for the ground you dig. The table shows the styles JMA stocks and the jobs they suit. Part numbers are examples from the current range; sizes that sell out are hidden until restocked, and US suppliers can get most others to us in 24–48 hours.
Replace teeth before they wear back to the adapter. A tooth worn short exposes the adapter nose, and a worn adapter means cutting it off and welding on a new one, which costs far more than a set of teeth.
Which Wear Part for Which Job
Trenching and hard clay
Single tiger and twin tiger teeth concentrate the machine's force on a point, so they bite into hard clay and cut clean trench corners. They wear faster than rock chisels, so keep a spare set on the truck.
Shop bucket teethGrading and final cleanup
Flare teeth are wide and flat, leaving a smoother surface and a cleaner trench bottom than pointed teeth. A common swap is rock chisel for digging, flare for finishing.
Shop bucket teethLoose pins and bucket slop
Worn bucket pins and missing shims let the bucket rattle on the stick and wear the bores oval. Replace pins in pairs and shim the gap before it becomes a machining job.
Shop bucket pinsRebuilding a worn lip
When a tooth has worn into the adapter, the adapter has to go too. Adapters and covers are stocked in Cat-style and ESCO-style patterns, with the matching pins and retainers.
Shop adaptersHydraulic hammer chisels
Blunt chisels break boulders and concrete, moil points split rock and pull the hammer into the work, and pile or grooved chisels suit driving and trench work. Hammer chisels run from 53 mm to 140 mm; match the diameter to your hammer.

Bucket Teeth and Wear Parts FAQ
Short answers on tooth types, sizes, replacement, adapters, warranty, returns and shipping.
The main styles are standard (general digging), rock chisel (rock and frost, longest wear), single tiger (one sharp point for hard clay and trenching), twin tiger (two points for trench corners and frozen ground), flare (wide and flat for grading and loading), long and penetration tip (loose material), and ripper teeth for ripper shanks. They come in tooth systems such as Caterpillar-style J-series, Hensley-style X156 and ESCO-style V23.
Read the part number cast on the side of the tooth or adapter. On Caterpillar-style J-series teeth the number gives the size: 1U3202 is J200, 1U3252 is J250, 1U3352 is J350 and 1U3452 is J450. If the number is worn off, measure the adapter nose and the pin hole and send us a photo; we match it before you order.
They are different locking systems. Each tooth only fits adapters of its own system, because the nose shape and pin arrangement differ. A Cat-style tooth will not fit an ESCO-style adapter. Match the system first, then choose the style.
Rock chisel teeth have a broad, heavy tip that resists wear in rock, frost and compacted ground. Tiger teeth have one (single tiger) or two (twin tiger) sharp points that penetrate harder material and cut corners, but they wear faster. Use tiger teeth to break in, rock chisels for long life.
Before the tooth wears back to the adapter. Once the adapter nose is exposed it wears quickly, and replacing an adapter means cutting it off and welding on a new one. Rounded, shortened or cracked teeth also make the machine work harder and burn more fuel.
Drive out the tooth pin with a pin punch, pull the old tooth off the adapter, clean the adapter nose, slide the new tooth on, fit a new retainer and drive the pin back through until it seats. Replace the pin and retainer each time; they are inexpensive and a worn retainer can let a tooth fall off.
Yes. JMA stocks Cat-style and ESCO-style adapters and covers, tooth pins, retainers, side cutters, a side bar protector, bucket shims and bucket pins. If a part is not in stock, US suppliers get it to us in 24–48 hours or we drop-ship it from a supplier near you.
No. Wear parts such as teeth, adapters, cutting edges, pins and bushings wear by design and carry no warranty. The attachment warranty (lifetime on structural welds, two years / 2,000 hours on manufacturing defects) covers the bucket itself.
No. Teeth, pins and similar consumables cannot be returned. Send us the part number or a photo before you order and we confirm the match.
Orders confirmed before 2 PM ET on a business day ship the same day from Miami, Florida. Parcel items (50 lb or less) go by FedEx or UPS, usually 5–7 business days; heavier attachments go by LTL freight, usually 7–10 business days, with a delivery appointment and signature. Liftgate service is available on request. Wear parts that are not on the shelf reach us from US suppliers in 24–48 hours, or ship directly from a supplier near you.
