The archive groups asserted targets as non-ferrous metals, non-metallic materials, and composites. Those lists are not current compatibility evidence. This matrix shows what would have to be identified before any exact blade-and-material statement could be evaluated.
Archived grouping, not a suitability answer
The old text names examples within each broad group, yet it binds none of them to a current blade model, bond, grit, geometry, machine, workpiece condition, test method, or acceptance record. Material names therefore remain unqualified source entries.
Qualification matrix for a reviewable statement
| Evidence axis | Identity required | Limit of the archive |
|---|---|---|
| Blade | Exact current product record and declared construction | No model, bond, grit, geometry, or current datasheet is bound |
| Machine | Identified machine documentation and compatibility record | No machine or approved configuration accompanies the list |
| Material | Exact material designation, condition, form, and relevant properties | Broad groups and examples do not establish equivalence |
| Test | Dated method, conditions, specimen identity, observations, and acceptance | No test record or measured result is supplied |
| Claim | Scope limited to the exact identities supported by that record | No general suitability, speed, quality, stability, or life conclusion |
Why the material groups remain separate evidence questions
Non-ferrous and non-metallic entries
A family label does not state grade, composition, reinforcement, hardness, form, coating, internal features, or condition. Without those identities and a matched test, the list cannot answer the title as a present recommendation.
Composite entries and the asbestos boundary
The archive includes asbestos among composite examples. This page does not promote cutting it and supplies no handling, containment, legal, industrial-hygiene, or disposal guidance. Such matters require specialist governance outside this article.
Answer supported by the available record
The historical material groups can be retained as questions for qualification, but they cannot resolve compatibility. The current title keeps its exact question mark because the body deliberately remains an evidence matrix rather than converting the archive into an answer.
