CSJ Crown Drill Bit,10D Drill Diameter Range 10.50-10.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

High-performance CSJ Crown Drill Bit featuring a 10D drilling depth capacity (Ø10.50–10.99 mm). Engineered with a front-locking body and internal cooling channels, it delivers exceptional stability, chip evacuation, and speed for deep-hole machining.

Product Description

The CSJ Crown Drill Bit is a state-of-the-art indexable drilling system designed for demanding high-speed, deep-hole applications. Utilizing a secure front-locking mechanisms with a side-locking drill tip, this tool guarantees maximum rigidity and seamless insert changes without removing the tool body from the holder. Its optimized internal cooling passage flushes chips efficiently directly from the cutting zone, extending tool life, reducing heat friction, and ensuring superior hole accuracy across tough materials.

Product Parameters

Product Function
