Step 01
Packet received
We list missing drawing, grade, quantity, destination, and inspection fields. Unknowns stay labeled unknown rather than filled with typical shop defaults.
Supplier matching workflow
Align each drill bit manufacturer on one RFQ
The matching desk restates a 4140 through-hole packet so every candidate drill bit manufacturer prices the same oil-hole, grind and inspection lines. Coolant-fed and solid-carbide routes stay on separate cells until the buyer writes which one governs. We do not swap your datums, coating notes, or FAI pack for a catalog default.
Quote lines to align
Each factory should price the same inclusions and exclusions
Drill-bit replies often diverge because shops bury flute-grind NRE, PVD coating batches, CMM programming, or diamond-segment braze inside a unit price. The list below is how we force those lines onto the page. Tooling amortization, coating minimums, and inspection hours are not interchangeable even when the diameter looks simple.
Sourcing sequence
Four intake gates before we treat quotes as comparable
The desk does not publish a shop-floor headcount. These gates exist so a missing coolant-through diameter or an unsigned 4140 hardness note cannot hide inside a friendly unit price.
Step 02
Process questions sent
Candidate shops receive the same questions on grind access, heat treat or sinter partners, coating vendors, and which reports ship with the lot.
Step 03
Scope normalized
Responses are lined up by inclusion, exclusion, currency, Incoterm, and validity. We do not invent a market discount to close a gap.
Scope questions
Costs that need a separate confirmation line
Coolant-fed or solid carbide on this 4140 hole?
Coolant-fed carbide can evacuate chips in a deep 4140 through hole, but the oil-hole diameter, collar and holder must match the machine. Solid carbide is simpler to grind and regrind, yet it can wander if pecks, web thinning and point angle stay unnamed. Ask each plant to price one route only, then write the other as an optional alternate.
Who owns special process work?
PVD coating, steam temper, or diamond-segment sinter may sit at a sub-tier. The quote should name that party or mark the process as buyer-furnished.
What does FAI include?
A ballooned drawing, CMM report, material certificate, and CoC are different deliverables. If PPAP is required, list the elements; a generic quality sentence is not a PPAP pack. Hole-location Cpk is a plant measurement on the buyer workpiece, not a number this desk can invent.
When is MOQ a process limit?
Some lots are driven by carbide rod remnant, coating batch size, or sinter furnace load. Ask for the driver instead of treating MOQ as a marketing number.
Send the drill bit manufacturer packet we should match
Include revision, grade, GD&T, quantity split, destination, and which reports must travel with the lot. Plant wholesale replies are then stacked on that shared 4140 scope; no savings percentage is published.
