The tooth and seat, shown together.
The cutting tooth is the replaceable wear element; its holder establishes the seating position on the casing shoe. The WS39 illustration shows the cutting profile and dimensioned views of the tooth body. Its holder has a different width and section, so tooth dimensions alone do not describe the installed assembly.

WS39
Distinct catalogue casing-tooth profile; WS39 and WS46 have different listed heights and different visible cutting/pin layouts.

WS39 Holder
The two tooth models have separately identified holders, even though their nominal dimensions match.
Request this configurationWS39 and WS46 are separate profiles.
| Component | Height | Width | Thickness | Selection difference |
|---|---|---|---|---|
| WS39 tooth | 109.5 | 68 | 41.5 | WS39 cutting / retention profile |
| WS46 tooth | 112.5 | 68 | 41.5 | Different height and illustrated profile |
| WS39 holder | 106.8 | 94 | 31.3 | Named holder for WS39 |
| WS46 holder | 106.8 | 94 | 31.3 | Separate named holder despite similar listed dimensions |
Similar widths and thicknesses do not establish interchangeability. The seat profile, pin engagement and mounted projection must match the shoe arrangement.
Distinguish tooth wear from a seating problem.
At the cutting end
Photograph the carbide edges and the supporting steel. Compare leading-edge wear, missing carbide and body erosion across teeth from different positions on the shoe. The location of the wear is more informative than a single overall photograph.
At the holder and retainer
Clean the seat before judging fit. Check whether the tooth sits fully home, whether the pin is correctly engaged and whether the holder or surrounding welds are worn. New teeth should be compared against the actual installed holder, including its service condition.
PRODUCT & PROJECT ENQUIRY
Identify the tooth and its complete fitting.
Include WS39, the tooth and holder quantities, photographs of the pin and seat, and the casing-shoe reference. We can then distinguish a tooth-only replenishment from a complete fitting requirement.
