CSJ Crown Drill Bit, 6D Drill Diameter Range 20.00-20.99, 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 (6D) is a high-performance, indexable deep-hole drilling solution engineered for precision and speed. Featuring an advanced front-locking body, internal cooling, and a side-locking drill tip, this tool delivers exceptional chip evacuation and extended tool life for hole diameters ranging from 20.00mm to 20.99mm.

Product Introduction

Engineered for demanding industrial applications, the CSJ Crown Drill Bit redefines efficiency in high-speed, deep-hole drilling. This 6D-length indexable insert drill combines the structural rigidity of a solid carbide drill with the cost-effectiveness of a modular system.

Equipped with a secure front-locking body and a stable side-locking drill tip mechanism, it ensures maximum clamping force and minimal runout under high torque. The integrated internal cooling system delivers coolant directly to the cutting edge, drastically reducing thermal wear and guaranteeing smooth chip evacuation even at extreme drilling depths.

Product Parameters

Product Key Functions

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

• Superior Thermal Management: Dual internal coolant holes flush out heat instantly, protecting both the workpiece and the drill tip from thermal deformation.

• Maximum Clamping Stability: The dual-action locking system (front-locking body + side-locking tip) eliminates micro-vibrations, ensuring high dimensional accuracy and excellent surface finish.

• Cost-Efficient Maintenance: The indexable crown tip design allows operators to replace only the worn drill tip rather than the entire drill body, significantly lowering tooling costs.

Application Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty manufacturing environments, including:

• Automotive Industry: Drilling engine blocks, crankshafts, and heavy powertrain components.

• Aerospace & Defense: Precision machining of high-strength alloy structural components.

• Mold & Die Making: Creating deep coolant channels and ejector pin holes in complex mold bases.

• Heavy Machinery: Production of hydraulic cylinders, oil & gas drilling equipment, and large-scale mechanical frames.

• Compatible Materials: Optimized for carbon steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
