CSJ Crown Drill Bit, 6D Drill Diameter Range 19.00-19.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

High-performance CSJ Crown Drill Bit (6D) engineered for high-speed, deep-hole drilling. Featuring a front-locking body design, advanced internal cooling system, and an indexable/side-locking drill tip, it delivers exceptional stability, chip evacuation, and precision for hole diameters ranging from 19.00mm to 19.99mm.

Product Introduction

The CSJ Crown Drill Bit represents the next generation of indexable deep-hole drilling technology. Designed to handle demanding industrial applications, this 6D drill combines the rigidity of a solid carbide tool with the cost-effectiveness of an indexable insert system.

Its innovative front-locking body ensures maximum clamping rigidity, drastically reducing vibration even during high-speed operations. Coupled with internal cooling channels that deliver coolant directly to the cutting edge, this drill bit minimizes heat friction and ensures seamless chip evacuation, significantly extending tool life and improving surface finish.

Product Specifications (Parameters)

Key Benefits & Product Functions

• High-Speed Deep-Hole Efficiency: The 6D depth capability allows for rapid, continuous deep-hole drilling without the need for frequent pecking cycles.

• Superior Internal Cooling: Dual internal coolant holes flush out chips efficiently and lower cutting temperatures, preventing thermal cracking of the insert.

• Maximum Rigidity (Front-Locking): The robust front-locking structure stabilizes the crown insert under high torque, ensuring excellent hole straightness and strict dimensional tolerance.

• Cost-Effective Maintenance: The indexable side-locking tip allows for quick insert replacement directly on the machine, minimizing downtime and reducing overall tooling costs.
