CSJ Crown Drill Bit,10D Drill Diameter Range 20.00-20.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description High-performance CSJ Crown Drill Bit (10D) engineered for deep-hole drilling (20.00–20.99 mm range). Featuring a secure front-locking body, internal cooling, and indexable/side-locking tips, it delivers exceptional speed, heat dissipation, and long tool life in demanding metalworking applications.

Product Introduction The CSJ Crown Drill Bit with 10D drilling depth capability is designed for high-precision, heavy-duty deep-hole processing. Equipped with a robust front-locking system and side-locking drill tip options, this indexable drill ensures rapid tip indexing and maximum clamping stability under high torque. Its optimized internal coolant channels deliver lubricant directly to the cutting zone, efficiently evacuating chips and preventing heat buildup during high-speed operations.
