CSJ Crown Drill Bit, 5D Drill Diameter Range 9.50-9.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

Engineered for maximum efficiency, the CSJ Crown Drill Bit features an advanced front-locking body and high-pressure internal cooling. Designed for 5D high-speed, deep-hole drilling, this indexable insert tool with a side-locking drill tip delivers exceptional stability, rapid chip evacuation, and superior hole accuracy in demanding industrial applications.

 Product Overview

The CSJ Crown Drill Bit (5D) represents the next generation of precision high-speed drilling technology. By combining a rigid front-locking body mechanism with a secure side-locking drill tip, this tool eliminates vibration and ensures precise tool runout control during deep-hole operations.

Equipped with integrated internal cooling channels, it delivers coolant directly to the cutting edge. This drastically lowers thermal stress, extends insert lifespan, and facilitates seamless chip evacuation. Its indexable crown-style insert design allows for quick tip replacements without removing the drill body from the machine, minimizing downtime and maximizing productivity.

 Key Functions & Features

• Advanced Internal Cooling: Through-body coolant holes deliver high-pressure fluid directly to the cutting zone, reducing heat friction and preventing chip clogging.

• Dual-Locking Stability: The front-locking design combined with a side-locking tip guarantees high rigidity, preventing deflection even at high feed rates.

• Cost-Efficient Indexable Design: Easily swap out worn crown tips without replacing the entire drill body, significantly reducing tooling costs per hole.

• Exceptional Deep-Hole Performance: Optimized 5D flute geometry ensures smooth chip evacuation, preventing chip pack and tool breakage during deep penetration.

 Target Applications & Scenarios
