CSJ Crown Drill Bit, 6D Drill Diameter Range 34.00-34.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

The CSJ Crown Drill Bit is a premium 6D indexable insert drill engineered for high-speed, deep-hole drilling operations. Featuring a front-locking body design and integrated internal cooling channels, this high-performance tool delivers exceptional chip evacuation, superior hole accuracy, and extended tool life. With a versatile drill diameter range of 34.00mm to 34.99mm and a secure side-locking drill tip, it is built to handle the most demanding heavy-duty machining tasks with ease.

Product Introduction

Designed for precision and endurance, the CSJ Crown Drill Bit series represents the next generation of indexable deep-hole drilling technology. The 6D length-to-diameter ratio allows for deep penetration without sacrificing rigidity. By utilizing a front-locking body structure, insert replacement is quick and seamless, drastically reducing machine downtime. The true powerhouse feature is its internal cooling system, which forces high-pressure coolant directly to the cutting edge, minimizing thermal deformation and ensuring smooth chip flushing. Paired with a robust side-locking drill tip system, this tool guarantees maximum stability under heavy torque and high-feed conditions.

Product Parameters

Product Functions (Product Action)

• High-Efficiency Deep Drilling: Seamlessly drills holes up to 6 times the tool’s diameter in a single pass without the need for peck drilling.

• Advanced Thermal Regulation: The dual internal coolant holes deliver precise fluid flow to lower cutting zone temperatures, preventing work-hardening of the material.

• Rapid Chip Evacuation: Specially designed chip flutes combined with high-pressure coolant push chips out out of deep cavities instantly, eliminating chip packing and tool breakage.

• High-Rigidity Locking: The combination of front-locking and side-locking mechanisms eliminates micro-vibrations, ensuring excellent surface finish and strict hole tolerance.

Application Scenarios

This industrial-grade drill bit is ideal for heavy manufacturing sectors requiring high-speed, repeatable deep-hole processing:

• Heavy Machinery & Energy: Drilling large-diameter tube sheets, heat exchangers, and turbine components.

• Automotive & Aerospace: Machining engine blocks, structural frames, and heavy-duty drivetrain components.

• Mold & Die Industry: Creating deep coolant lines and core pins in large injection molds.

• General Engineering: Efficiently processing structural steels, alloy steels, stainless steels, and cast iron in high-volume CNC machining centers.
