CSJ Crown Drill Bit, 4D Drill Diameter Range 8.50-8.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

The CSJ Crown Drill Bit (4D) is a high-performance, indexable insert drill body designed for high-speed, deep-hole drilling applications. Featuring an advanced front-locking mechanism for rapid tip replacement and internal cooling channels for superior chip evacuation and heat reduction, this tool ensures exceptional stability, precision, and extended tool life in demanding machining environments.

Specifications

Applications & Use Cases

• High-Speed Deep-Hole Drilling: Engineered specifically for efficient 4D depth drilling without compromising surface finish or dimensional accuracy.

• Diverse Material Machining: Ideal for drilling steel, alloy steel, cast iron, and other challenging metals in CNC machining centers, lathe machines, and boring mills.

• High-Efficiency Production: Perfect for manufacturing setups requiring minimal downtime, as the front-locking system allows for quick insert changes directly on the machine.

Key Product Highlights (Bullet Points for Listings)

• Optimal Chip Evacuation: Dual internal coolant holes deliver high-pressure fluid directly to the cutting edge, reducing thermal stress and flushing chips efficiently.

• Rigid 4D Construction: Offers the perfect balance of reach and structural rigidity to minimize deflection during high-speed operations.

• Cost-Effective Indexable Design: No need to regrind; simply replace or index the crown drill tip to maintain peak cutting performance.
