Mechanical engineering tools can sell online. Most people just market them the wrong way. Engineers, technicians, students, and workshop owners search daily for precision tools like digital calipers, torque wrench sets, laser distance meters, and welding holders. These are solution products. Not impulse buys. That means repeat customers and long term value. You do not need inventory to start. With dropshipping, your supplier ships directly to your customer. I recommend starting with Shopify. It is simple, professional, and built for global selling. If you started today, which tool would you sell first?
