CSJ Crown Drill Bit, 4D Drill Diameter Range 33.00⁓33.99, 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 high-performance, indexable front-locking 4D drill body designed for high-speed, deep-hole drilling. Engineered with internal cooling channels and a robust side-locking drill tip mechanism, it offers exceptional stability, precise chip evacuation, and a drilling diameter range of $\varnothing$ 33.00mm to 33.99mm.

Product Introduction

The CSJ Crown Drill Bit series represents the next generation of indexable deep-hole drilling technology. Featuring a advanced 4D depth-to-diameter ratio and an innovative front-locking body design, this tool ensures maximum rigidity and minimal runout during heavy-duty machining.

By integrating a side-locking drill tip/insert mechanism, tool changes are fast, secure, and require zero disassembly from the machine spindle. Equipped with optimized internal cooling holes, it delivers coolant directly to the cutting edge, drastically reducing thermal wear and ensuring seamless chip evacuation in deep cavities.

Product Parameters

Key Features & Benefits (Product Functions)

• High-Speed Deep-Hole Efficiency: The 4D ratio combined with high-speed indexing allows for rapid material removal in deep bores without compromising accuracy.

• Advanced Internal Cooling: Dual internal coolant channels lower cutting-zone temperatures, prolonging insert life and forcing chips out smoothly to prevent clogging.

• Front-Locking Stability: The front-locking mechanism provides superior clamping force, reducing vibration and ensuring excellent surface finish and hole linearity.

• Cost-Effective Indexable System: The side-locking insert tip allows operators to replace worn crowns quickly, reducing machine downtime and overall tooling costs.

Applications & Target Scenarios

This industrial-grade drill bit is ideal for heavy-duty manufacturing and precision engineering sectors, including:

• Industries: Automotive manufacturing, aerospace, oil & gas equipment, wind power components, and heavy mold/die making.

• Applicable Materials: Carbon steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.

• Machining Operations: High-speed deep-hole drilling, large-diameter boring, and batch production on CNC machining centers, milling machines, and boring mills.
