To get a comparable quote for diamond tools from a China manufacturer, send one RFQ that pins down four things: exact specifications (size, bond/grit, welding type, mounting), quantities per SKU, destination port and Incoterm, and target-market certifications. Reputable factories such as JOY TECH reply within 1-3 working days with FOB pricing, sample terms, MOQ and lead time. Expect indicative FOB bands of $0.8-$3.5 per piece for grinding shoes, $15-$90 per piece for 350 mm laser-welded blades, and $10-$60 per piece for wet core bits at order quantities of 100+ pieces.
| Incoterm | The price includes | Best when |
|---|---|---|
| FOB (Xiamen port) | Factory price + inland trucking + export clearance; you book and pay ocean freight | You have a forwarder and want the factory price transparent |
| CIF (your destination port) | FOB + ocean freight + insurance to your port | You want one landed estimate; duties are still yours |
| DDP (your door) | All freight, duties and customs clearance | Small trial orders; price is higher but fully predictable |
A blade quoted at $38 FOB Xiamen can still be cheaper than one at $42 CIF Rotterdam - always compare the same Incoterm, and ask whether the quote is FOB before judging price.
For a first order, agree three things in writing: a first-article sample approval, outgoing QC (dimensional check, runout and balance for blades, visual weld inspection), and a rejection/replacement clause for defective units. If you want eyes on the container, third-party inspection firms (SGS, BV, or your own QC agent) are welcome at most factories with a few days notice. Keep the spec sheet, proforma invoice and approved sample linked together - that is what makes any quality claim fast to resolve.
A $28 blade and a $42 blade may look identical on paper but differ in bond grade, segment height, core steel (65Mn vs a higher alloy), welding method (brazed vs laser) and balance quality. When comparing quotes, ask every factory to confirm the same five specs - bond code, segment height, core steel grade, welding type and batch QC records - then compare. Two quotes that match on those five points are actually comparable; the cheaper of those wins.
A: Typically 1-3 working days for standard stock items, 3-7 days for custom spec or formula questions. Anything same-day usually means the factory guessed your spec rather than engineering it.
A: Samples are usually charged at cost price plus courier; professional factories credit the sample fee to your first bulk order. "Free" samples are usually padded back into a higher unit price later.
A: As an indicative band: 50-100 pieces per SKU on stock tooling, 200-500 pieces per SKU with your logo. Send quantities you can actually buy - factories tune the price to your real numbers.
A: Yes. Factories that carry a full line (grinding, cutting, drilling, polishing) can mix SKUs in one container, which also raises the discount level of the whole order.
A good quote is the factory answer to a good RFQ: exact specs, per-SKU quantities, Incoterm and certifications spelled out up front. Send JOY TECH your tool list - for example the Diamond Trapezoid Grinding Disc (JOY-TP-R3), a Concrete and Asphalt Saw Blade (Laser Welded) - JOY-CA-LW and Diamond Core Drill Bit (Wet) - JOY-DCB-W - with your machine models and destination port, and you get FOB pricing, sample terms and MOQs in one comparable reply.
