A 7D U drill is a high-speed indexable insert drill designed for drilling depths up to 7 times the drill's nominal diameter, offering efficient chip evacuation and precise deep-hole drilling.
Made from premium alloy steel, this CNC U drill is capable of processing a wide range of materials including structural steels, alloy steels, stainless steels, and cast iron.
Yes, this drill features internal cooling channels designed to deliver coolant directly to the cutting edges, which helps reduce heat buildup and facilitates smooth chip flushing during deep-hole operations.
U drills offer significantly higher feed rates, eliminate the need for center drilling or pilot holes, and allow easy replacement of carbide inserts rather than resharpening the entire tool.
To ensure safe chip evacuation at 7D depths, it is highly recommended to use adequate coolant pressure (preferably internal coolant) and ensure consistent machine rigidity.
