CSJ Crown Drill Bit,10D Drill Diameter Range 9.00-9.49, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

The CSJ 10D Crown Drill Bit with a front-locking body deliver high-speed, precision deep-hole drilling for diameters ranging from 9.00mm to 9.49mm. Engineered with an internal cooling system and side-locking replaceable drill tips, it optimizes chip evacuation, reduces thermal wear, and ensures high efficiency in demanding machining operations.

Product Overview

Designed for challenging high-speed deep-hole applications, the CSJ 10D Crown Drill combines structural stability with indexable versatility. Featuring a front-locking body mechanism and a side-locking drill tip, this tool enables fast tip replacements without removing the drill body from the machine spindle, drastically minimizing setup downtime. Its integrated internal cooling channels deliver high-pressure coolant directly to the cutting edge, breaking chips effectively and extending tool life under heavy continuous operations.
