CSJ Crown Drill Bit, 3D Drill Diameter Range 9.50-9.99mm, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

The CSJ Crown Drill Bit (9.50–9.99mm Range) is a high-performance, indexable insert drill engineered for high-speed, deep-hole drilling operations. Featuring an advanced front-locking body design and integrated internal cooling (thru-coolant) pathways, it ensures exceptional chip evacuation, reduced thermal wear, and superior hole accuracy. Equipped with a secure side-locking drill tip mechanism, this tool delivers the rigid stability and rapid cycle times required for demanding industrial manufacturing.

Technical Parameters

Applications & Uses

• High-Speed Deep-Hole Drilling: Optimized for high-RPM CNC machining centers, milling machines, and specialized drilling rigs where cycle-time reduction is critical.

• Precision Bore Machining: Ideal for applications demanding tight dimensional tolerances and excellent surface finishes within the $9.50\text{ mm}$ to $9.99\text{ mm}$ range.

• Excellent Chip Evacuation: The combination of the 3D flute geometry and internal cooling makes it perfect for blind holes and deep cavity pocketing without chip packing.

• Versatile Material Processing: Suitable for high-efficiency drilling across a wide range of industrial materials, including:

  • Carbon steel and alloy steels

  • Stainless steel (e.g., 304/316)

  • Cast iron

  • High-temperature alloys and non-ferrous metals
