The M20169 Cummins NT N‑14 Chip Catcher Set of 6 is a precision shop accessory designed to make counterboring operations on Cummins and Caterpillar engines cleaner, safer, and more efficient. This set of six chip catchers is specifically sized for 5.5″ Cummins NT/N-14 bores and 5.4″ Caterpillar 3406 C15 bores, allowing technicians to capture metal chips and dust generated during counterbore machining—reducing engine contamination and cleanup time.
During heavy-duty diesel engine rebuilds—such as preparing a block for liner installation or sleeve fitting—counterboring creates metallic debris that can fall deep into cylinder holes, oil galleries, and coolant passages. Left uncontrolled, these chips can cause internal scoring, premature wear, and expensive rework. The M20169 chip catcher set fits standard counterbore tools and blocks this debris at the source, improving shop safety and protecting engine components.
This set is an essential addition for professional shops, fleet maintenance departments, and remanufacturing facilities that regularly perform Cummins NT/N-14 and Caterpillar 3406 engine service—helping maintain a clean working environment and ensuring more reliable engine restorations.
