CSJ Crown Drill Bit, 3D Drill Diameter Range 17.00-17.99mm, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

The CSJ Crown Drill Bit is a high-performance, indexable drilling solution engineered for high-speed, deep-hole machining. Featuring a specialized front-locking body paired with a secure side-locking drill tip, this tool ensures maximum stability, structural rigidity, and seamless insert replacement without removing the body from the holder. Equipped with internal cooling channels, it provides exceptional chip evacuation and thermal management, significantly extending tool life and delivering precision holes at a 3D drilling depth.

Technical Parameters

Key Applications & Uses

• High-Speed Deep-Hole Drilling: Ideal for operations requiring rapid, high-precision hole making up to a 3D depth without sacrificing surface finish.

• Excellent Chip Evacuation: The internal cooling system blasts coolant directly to the cutting edge, making it perfect for blind holes and sticky materials where chip packing is a risk.

• Versatile Material Machining: Suitable for high-efficiency drilling in steel, alloy steel, cast iron, and stainless steel components.

• Mass Production: The front-locking indexable design minimizes downtime for insert changes, making it highly effective for CNC machining centers and automated production lines.
