BAUER Type Trench Cutter Teeth SB42JR / SB42JF: replace tooth view

A trench cutter tooth is a small part with an expensive failure mode. If it does not seat correctly in the wheel pocket, the symptom shows up later — movement in the pocket, uneven wear, unplanned wheel downtime. So we filmed the BAUER type trench cutter teeth SB42JR / SB42JF rotating on the inspection plate rather than shooting one hero photo: the whole geometry, in one pass.

What the 360° view shows

Three areas a buyer normally has to ask about:

- Shank and mounting face. How the tooth seats in the cutter wheel pocket.
- Taper and cutting tip. The wear-critical geometry, seen from the working side.
- Full side profile. The face a catalogue photo leaves out.

It does not replace a dimensional report, but it answers the first question faster: is this the shape I am already running?

Where these teeth are used

SB42JR and SB42JF are replaceable cutter teeth mounted on the cutting wheels of BAUER-type diaphragm wall trench cutters, also described as hydromill or hydrofraise teeth. They cut through sand, gravel, cobbles and weathered rock in diaphragm wall and cut-off wall construction.

Choosing the right tooth without a part number

Both models belong to the same tooth family. If you already know the reference, quote it and we produce to that drawing. If you do not — the normal case here, since the number is usually gone from the pocket before the tooth is worn out — we work from the part instead: send the worn tooth, a photo of it, or a drawing. We read the seat, the taper and the wear pattern, cut the tooling and produce the replacement. Close to 20 years of forging and machining on wear parts is what makes that routine rather than a special case.
