How it works

Your request goes to the selected supplier, and optionally up to 3 others with a fit.
Suppliers quote price, stock and lead time to you. You decide; no checkout here.

Offers from suppliers that ship within or into Australia. AUD is the basis for any illustrative numbers. No Boretrade warehouse — the supplier ships.
Planned after Australia. US suppliers can already appear as ship-from origins on sample offers.
Planned after the US. Canadian surplus brokers appear in the sample data for cross-border sourcing.
FAQ
No. Enter the specification, quantity, destination and a work email. The selected supplier quotes you directly.
No live prices. Offers are quote-only because freight, quantity and exact specification change the price. Where an illustrative figure is used it is marked and in AUD.
No. There is no Boretrade warehouse. Suppliers confirm stock and lead time on every quote.
Not necessarily. DTH shanks, pin connections and cutter mountings must match exactly; nominal size alone does not confirm fit. Ask for technical help if unsure.
