Casing teeth & holders
Replaceable casing teeth and holders for casing shoes. Compare the actual WS39 and WS46 profiles, their separate seats and the complete retention arrangement.
Two tooth profiles. Separate matched seats.
The casing-tooth family covers the cutting elements mounted around the shoe. Choose the tooth and holder as a pair, then check their installed cutting projection and retention. WS39 and WS46 remain separate catalogue models.

WS39 Holder
106.8 × 94 × 31.3 mm listed holder envelope. Match the named tooth and its seat geometry; equal outer dimensions do not establish interchangeability.
Request this configurationWS46
112.5 × 68 × 41.5 mm catalogue envelope: 3 mm taller than WS39. The profile and retention arrangement remain model-specific.

WS46 Holder
106.8 × 94 × 31.3 mm listed holder envelope. Match the named tooth and its seat geometry; equal outer dimensions do not establish interchangeability.

| Element | What it does | What defines the selection |
|---|---|---|
| Tooth | Presents the carbide cutting profile to the ground | Tooth profile, mounted projection and wear pattern |
| Holder | Locates and supports the tooth on the shoe | Seat geometry, welding surface and shoe position |
| Retention | Keeps the replaceable tooth engaged | Pin/retainer configuration and full engagement |
| Shoe | Carries the cutting ring at the casing toe | Inner/outer cutting envelope and tube connection |
When replacing only part of a worn ring, compare new and remaining tooth projection around the shoe. A nominally correct individual tooth does not resolve unequal holder positions or a damaged shoe body.
Use the dimensions to identify the model, then confirm the fit against the order drawing.
