哥伦比亚采购需求：有线工具、角磨机、电镐、锤钻、冲击钻、旋转锤

I'm interested in obtaining detailed specifications and pricing for a range of agricultural tools. Could you provide me with a comprehensive list of the available products, including their features and any relevant options? Additionally, if there are bulk purchase discounts or ongoing promotions, please include that info as well. I'm looking forward to reviewing the materials you send over so I can make an informed decision. Thanks!
