Frequently Asked Questions

Should I purchase industrial machinery from a tool shop or reseller, or from an industrial machinery specialist?

Tool shops and general resellers may offer a wide product range, but often lack the specialised knowledge to properly assess applications or provide ongoing technical support. An industrial machinery specialist ensures the right machine is selected and fully supported long after purchase. In most cases, buying directly from the importer or specialist also results in a lower purchase cost, as additional reseller margins are not added.

What after-sales support and warranty do you provide?
