Chengdu Tool Research Institute Co., Ltd.

Chengdu Tool Research Institute Co., Ltd. is a long-established supplier, having been in business since 1993 — which suggests stability and experience in tool manufacturing. Their key products like cemented carbide and carbide drill bits are standard in machine tool industries, making them a credible option for industrial buyers. Unlike many new suppliers, their long history gives them a proven track record, which is especially valuable in technical and precision tool markets. However, none of their contact details — phone, work email, or business documents — have been verified, which raises a red flag for buyers concerned about legitimacy and responsiveness. Without verified communication channels, it's hard to confirm their availability or ability to respond to urgent inquiries. Buyers should request additional verification before placing large or time-sensitive orders. While the company's product range is solid, the lack of verification means trust must be built through direct outreach and due diligence.
