Product: Heat-set insert driver tip for embedding threaded inserts into plastic parts. Note: 1 carton contains 7 pieces. Key benefits - Fast, repeatable installation of heat-set inserts into plastic parts, reducing effort and rework. - Brass construction and CNC fine turning provide reliable heat transfer and precise contact for straight, flush insert seating. - Interchangeable head design with internal thread and knurled joint lets you swap insert bodies after the tool has cooled for flexible use across sizes. - Compact embed depth and rounded head contact minimize damage to surrounding plastic and prevent insert tilting. Specifications and compatibility - Material: Brass, CNC fine-turned finish. - Compatibility: Fits standard 936-type universal soldering iron tips for convenient use with common soldering handles. - Supported insert sizes: M2, M2.5, M3, M4, M5, M6 (1/4 inch), M8. - Design features: Internal threaded head, hand-turnable knurled joint, detachable insert bodies for quick size changes. - Packaging: 7 pieces per carton. Performance and design highlights - Brass offers good thermal conductivity for fast, even heating and consistent embed results. - Face-to-face contact design reduces the risk of insert tilt and ensures accurate alignment during installation. - Short embedding distance and rounded head profile protect delicate plastic features and allow controlled insertion depth. - Compatible with common soldering tips to keep setup simple and practical for workshop or desktop use. Typical applications - Installing metal threads into 3D printed parts for secure fastener mounting in prototypes and functional prints. - Repairing or reinforcing threaded mounting points in hobby electronics enclosures, RC models, and consumer product prototypes. - Assembly of small plastic components that require durable metal threads for repeated fastening and maintenance. This brass heat-set insertion tip set is a practical tool for makers, technicians and engineers who need precise, repeatable embedding of threaded inserts into plastic components.
