Supplier QMS certificates
ISO 9001, AS9100D, IATF 16949 and ISO 13485 are requested from the named site. A logo wall would imply ownership we do not have.
Buyer sends drawing, grade, quantity and destination. Missing items stay listed, not guessed.
We turn the packet into a factory-facing RFQ with include/exclude language.
Candidate shops answer process, inspection and document scope. Claims stay unverified until files arrive.
You receive a comparison table. Award and payment stay with the buyer and the chosen supplier.
Drill Bit Suppliers Sourcing exists so a manufacturing engineer can keep one 4140 through-hole revision in front of several candidate shops. We rewrite the brief into include and exclude language, then we ask each shop to answer grind route, oil-hole access, inspection hours and document scope. Replies stay plant statements; they do not become a desk-owned discount or a spindle-count story.
When a shop mentions ISO 9001 or AS9100D, we treat the statement as a file to request for the named site and the named revision. The same rule applies to coating records, carbide rod certificates and CMM report format. Hole-location Cpk is requested from the plant against the buyer fixture, never typed here as a site KPI. If the buyer already has a preferred shop, say so; a second quote is still useful only when it uses the same diameter table and the same quantity layers.
No founding year is listed because brand_config does not contain one. No customer count is listed because that asset is also absent. The desk publishes the method, not a plant tour.

ISO 9001, AS9100D, IATF 16949 and ISO 13485 are requested from the named site. A logo wall would imply ownership we do not have.

Spindle count, Cpk and DPPM are factory measurements. They appear only after a supplier writes them against your revision.

No testimonial file exists in brand_config, so this page uses process facts instead of invented names.
If you already have one shop and only need a second same-basis quote for a 4140 through-hole lot, say so in the brief. Preference for high-end, mid-range or budget sources is a buyer filter, not a rating we have audited.
