Product Overview
The standard rock profile on pin, aimed at 20-22 ton machines doing ordinary excavation, road works and site preparation. It is the everyday tooth of the range, not a speciality part.
The tooth is cast, heat treated and machined in our own foundry. Part number PC200TV is cast on the tooth body, so the number on the part matches the number on this page and on the packing list.

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 PC200TV 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
Consistent Wall Thickness
Resin bonded sand moulds and a fixed pattern give even wall thickness, so weight per piece does not drift between shipments.
Tolerance Held On CNC Centres
Pin bore, mounting faces and the tip profile are cut on CNC centres within plus or minus 0.1 mm, batch after batch.
Small Trial Orders Accepted
A trial order of 20 pieces is enough to run a comparison on your own site before you commit to a container.
Hardness Verified Every Batch
A hardness test is run on every production batch and the reading is written on the packing list, so you can compare it with the sample you approved.
Wear Rate Measured In The Field
We track wear on return samples from quarry customers and adjust the alloy when a size wears faster than the rest of the range.
Packed For Sea Freight
Teeth are oiled, bagged and cased so they arrive without rust bloom even after six weeks on the water.

About The Supplier
We have been supplying excavator spare parts since 2013 to customers in more than forty countries. The product range covers ground engaging tools, buckets, hydraulic components, undercarriage parts and engine parts for machines from three to ninety tons.
Where It Is Used
Road construction, building site bulk earthworks and general trenching. Where ground conditions vary through the day, a standard profile is the safest compromise between penetration and wear life.
Questions Buyers Ask
Q: How does it compare with a chisel?
A: It penetrates a little less but wears longer on abrasive soil. If your ground is a mix of soil and loose rock, the standard profile is the practical pick.
Q: Can I mix it with other profiles?
A: Yes, many customers run chisel teeth in the centre and standard teeth on the outside of the lip. Tell us the layout and we will pack accordingly.
Q: What is the packing?
A: Bagged or wooden cased as you prefer, oiled against rust for sea freight.

Fitting And Care
Rotate teeth between positions when you notice uneven wear. Moving the centre teeth to the outside spreads wear across the set and buys extra hours.
- 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.
