Here is a professional, high-converting product listing tailored for your CSJ Crown Drill Bit.

Short Description

The CSJ Crown Drill Bit (6D, Ø22.00–22.99mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an innovative front-locking body with internal cooling and a secure side-locking drill tip, it delivers exceptional stability, chip evacuation, and precision in heavy-duty machining.

Product Introduction

Take your deep-hole drilling operations to the next level with the CSJ Crown Drill Bit. Designed for demanding industrial applications, this 6D length-to-diameter ratio drill body accommodates a diameter range of 22.00mm to 22.99mm.

At its core is an advanced front-locking system combined with a side-locking drill tip, ensuring zero slippage and maximum rigidity under high torque. Equipped with dual internal cooling channels, it delivers coolant directly to the cutting edge to reduce thermal stress and seamlessly flush out chips. Whether you are using it as an indexable insert drill or a modular spade-style drill, this tool guarantees excellent hole accuracy, reduced downtime, and an extended tool life.

Product Parameters

Key Functions & Benefits (Product Action)

• High-Speed Deep-Hole Penetration: The 6D reach allows for deep precision drilling without sacrificing speed or risking deflection.

• Dual-Locking Stability: The combination of front-locking and side-locking mechanisms completely eliminates tip micro-vibrations, ensuring perfect concentricity.

• Advanced Thermal Management: Internal cooling channels lower cutting zone temperatures, preventing work hardening of the workpiece and protecting the insert edges.

• Cost-Efficient Indexable Design: No need to replace the entire drill body; simply swap or index the crown insert tip when worn, significantly lowering tooling costs per hole.

Application Scenarios

This industrial-grade drill bit is highly versatile and optimized for heavy machinery, automotive, and energy sectors.

• Machinery & Heavy Equipment: Drilling deep structural holes in tube sheets, large flanges, and heavy frames.

• Automotive & Aerospace: High-speed processing of engine blocks, drive shafts, and landing gear components.

• Oil, Gas & Energy: Deep-hole machining for piping systems, valves, and pressure vessels.
