CSJ Crown Drill Bit, 6D Drill Diameter Range 32.00-32.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

The CSJ Crown Drill Bit is a high-performance indexable insert drill engineered for precision deep-hole machining. Featuring a robust front-locking mechanism and an advanced internal cooling system, this 6D tool body ensures maximum stability, rapid chip evacuation, and exceptional tool life during high-speed drilling operations.

Product Introduction

The CSJ Crown Drill Bit represents the next generation of indexable drilling technology. Designed with a high-rigidity 6D body, it is specifically built to handle deep-hole applications where structural stability and accuracy are non-negotiable.

The innovative front-locking body secures the exchangeable side-locking drill tip firmly in place, allowing for quick, seamless insert changes directly on the machine—minimizing downtime. Combined with precise internal cooling channels, the tool delivers coolant exactly where it is needed most, drastically reducing thermal stress on the cutting edge and facilitating smooth, continuous chip evacuation.

Product Parameters

Product Functions (Product Benefits)

• Efficient Deep-Hole Machining: The 6D depth capability allows for deep, straight holes without the need for multiple peck-drilling cycles.

• Superior Thermal Management: Dual internal cooling channels direct high-pressure coolant straight to the cutting zone, suppressing heat generation and protecting the workpiece.

• Exceptional Rigid Clamping: The combination of a front-locking body and side-locking drill tip eliminates vibration, ensuring tight hole tolerances and excellent surface finish.

• Cost-Efficient Maintenance: Instead of replacing the entire drill body, you only replace the worn-out carbide crown tip, significantly reducing tooling costs per hole.

Application Scenarios

The CSJ Crown Drill Bit is optimized for heavy-duty manufacturing and CNC machining centers across various demanding industries:

• Heavy Machinery & Automotive: Drilling engine blocks, hydraulic cylinders, and drivetrain components.

• Mold & Die Manufacturing: Creating deep water cooling lines and ejector pin holes in large mold bases.

• Energy & Power Generation: Machining tube sheets, heat exchangers, and wind turbine structural flanges.

• Materials Compatibility: Highly effective for high-speed drilling in carbon steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
