Product Overview
This pin rock chisel tooth is cut for general rock and trenching work on 20-25 ton machines. The chisel profile concentrates digging force on a narrow edge, so it penetrates hard ground instead of riding on top of it.
The tooth is cast, heat treated and machined in our own foundry. Part number 1U3352RC is cast on the tooth body, so the number on the part matches the number on this page and on the packing list.

Fitment Notes
Fits adapters that take a 40 mm pin on the 20-25 ton class. Send the adapter nose dimension if you are unsure.
- Machine class: 20-25 ton
- Pin diameter: pin and retainer supplied
- Jobs: rock chisel
- Matching adapter, pin and retainer available in the same order
Casting Process
The tooth starts as a sand mould and ends as a machined part under the same roof. Eight stations, one batch number, so the 1U3352RC you receive behaves like the sample we quoted.
1. Pattern and mould
A hardened pattern forms the sand cavity. Resin bonded sand is rammed in a flask and the cavity is inspected at the start of every shift.
2. Melting and analysis
Clean billet is melted in a medium frequency induction furnace, then a spectro sample is pulled and the alloy corrected before tapping.
3. Pouring
Metal is poured between 1550 and 1600 degrees C with the heavy section fed first so the working tip stays sound.
4. Knock out and blast
The casting is shaken out, riser and gate cut away, then shot blasted to a clean grey surface.
5. Quench and temper
Batches are quenched and tempered to HRC 48-52, giving a hard tip over a tough mounting body.
6. Machining
Pin bore and mounting faces are cut on CNC centres to plus or minus 0.1 mm.
7. Inspection
Hardness, dimensions and sample impact tests are recorded against the batch number.
8. Packing
Teeth are oiled, bagged or cased, then photographed before the container is sealed.
Why This Tooth
Alloy Steel Billet, Not Scrap Melt
We melt clean billet and returned risers with a known analysis instead of mixed scrap, so carbon and chromium stay inside a narrow band from heat to heat.
Pin Bore Machined After Heat Treatment
Machining happens after quenching, not before, so the bore does not distort and the pin still slides in by hand months later.
One Order Covers A Mixed Fleet
Because the range follows the common mounting dimensions, a single purchase order can cover machines of several makes working on the same site.
Adapter Compatibility Checked
Before shipping we match the tooth to the adapter nose dimension you are running, which avoids the classic problem of a tooth that fits the pin but not the lip.
Surface Cleaned By Shot Blast
Shot blasting removes sand burn and scale, which makes the casting easy to inspect and gives paint something to grip.
Fast Answer On Fitment
Send a photo of the old tooth and the adapter nose and we will confirm the number the same working day.
Where It Is Used
Typical use is foundation excavation, utility trenching and quarry face clean up. On mixed ground the chisel point keeps a sharper edge than a wide tooth and loads the bucket faster.

Questions Buyers Ask
Q: Can it run in wet clay?
A: Yes, but clay packs between the teeth. A wide tooth is usually a better choice for pure clay, the chisel is at its best in rock and compacted ground.
Q: How often should it be checked?
A: Check tightness after the first four hours and then every fifty hours. A loose tooth wears the adapter nose, which costs far more than a new pin.
Q: Do you supply the matching pin?
A: Every tooth ships with a new pin and retainer. Reusing an old lock is the usual reason a fresh tooth comes off.
Fitting And Care
Clean the adapter nose before fitting and replace the pin with the tooth. Weld repair on a worn point destroys the hardness and is not recommended.
- Clean the adapter nose and socket before fitting, remove dirt, rust and burrs.
- Fit a new pin and retainer with every new tooth.
- Check tightness after four hours, then every fifty hours.
- Replace at about 30 percent tip wear to protect the adapter.
