Efficiently Tackle Urine Scale and Debris Handcrafted for precision and efficiency, the Medium Duty: Mini Chain Knocker is tailored for plumbing professionals tackling smaller diameter pipes ranging from 40mm (1 ⁹⁄₁₆”) to 50mm (2″). Its agile design ensures thorough descaling, efficiently breaking down urine scale to maintain clear and flowing pipes. To navigate through tight bends in smaller pipes like 50mm (2″), the risk of chain getting snagged is usually higher. To avoid this, we recommend keeping the drill spinning during retraction. This allows the chain to bounce off bends and eventually safely to your toolkit. The retrieval process is also on point with these chains. Keeping the drill spinning during retraction allows the chain to "bounce" off bends, avoiding snags and ensuring a smooth withdrawal. How does it perform compared to other chain knocker options? While it navigates with unparalleled flexibility in tight spaces, it trades off some descaling speed compared to its 1-Chained and 2-Chained counterparts. The Mini Chain is an excellent choice when working with very small diameter pipes and/or you need very small chain to clear way for the bigger ones. For those needing a balance between flexibility and speed, consider the 1-Chained or 2-Chained options. If you mostly have straight and bigger in diameter lines with barely any bends we highly recommend the 3-Chained option to speed things up. Ideal for hard materials like Cast Iron, Galvanized Steel, and Vitrified Clay Pipes, this Mini Chain is crafted for heavy-duty use. Always ensure the pipe condition can handle its rigorous capabilities. For delicate operations in PVC or similar materials, explore lighter duty options to prevent damage. Available in following sizes: 50mm (2″) for flex shaft thicknesses of 6mm (¼″) and 8mm (⁵⁄₁₆″) If you're looking for even smaller chain, we recommend checking out the Heavy Duty Mini Chain or Light Duty Mini Chain. What other Mini Chain choices do I have? Heavy Duty Mini Chains: Great chhoice for small diameter hard metal pipes when you are looking for maximum durability and slightly less descaling power. Light Duty Mini Chains: For PVC pipes, the Light Duty is your best bet. It is engineered without hard metal tips, making it the safest option for delicate materials, while still providing effective descaling action.
