CSJ Crown Drill Bit, 3D Drill Diameter Range 12.00-12.99mm, 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 insert drill engineered for high-speed, deep-hole drilling applications. Featuring an advanced front-locking body paired with a secure side-locking drill tip, this tool ensures exceptional stability, minimal vibration, and precise hole accuracy. Equipped with a state-of-the-art internal cooling system, it effectively dissipates heat and evacuates chips directly from the cutting zone, significantly extending tool life and maximizing machining efficiency.

Technical Parameters

Applications & Uses

The CSJ Crown Drill Bit is designed for heavy-duty industrial machining where precision and speed are critical.

• High-Speed Deep-Hole Drilling: Optimized for cutting deep holes up to 3 times the diameter (3D) without sacrificing accuracy or surface finish.

• Versatile Metalworking: Ideal for drilling a wide range of materials, including carbon steel, alloy steel, stainless steel, and cast iron.

• CNC & Automated Machining: Perfectly suited for CNC machining centers, lathe operations, and high-efficiency production lines.

• Intermittent & Solid Cutting: The dual-locking mechanism handles high torsional forces, making it reliable for cross-hole drilling and interrupted cuts.
