CSJ Crown Drill Bit,10D Drill Diameter Range 17.00-17.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description The CSJ Crown Drill Bit (10D) is a high-performance indexable drilling tool engineered for deep-hole applications. Featuring a front-locking body, side-locking drill tip, and internal cooling channel design, it delivers exceptional chip evacuation, high-speed stability, and extended tool life for hole diameters ranging from 17.00mm to 17.99mm.

Product Introduction Designed for demanding industrial deep-hole machining, the CSJ 10D Crown Drill Bit combines rigid structural integrity with precision cutting performance. Its innovative front-locking system and side-locking drill tip allow for rapid tip replacement directly on the machine, drastically reducing setup times and machine downtime. Integrated internal cooling channels feed coolant directly to the cutting zone, effectively reducing thermal load, dissipating heat, and ensuring smooth chip removal during high-speed 10D deep-hole drilling operations.
