A reliable supplier is found by checking process, QC and communication - not just the price list. Walk away from any diamond tooling vendors that shows these red flags: 1) no verifiable certification documents numbers, 2) vague bond/grit stage specifications, 3) no manufacturing plant address or proof, 4) refuses assess samples or video of production, 5) price far below market with no quality explanation, 6) no defined QC or guarantee terms, 7) pressure for full payment before any documentation. Sourcing diamond tooling from China is safe when you buy from audited producers — the risk comes from trading companies and ghost manufacturing plants that cannot prove what they sell.
