CSJ Crown Drill Bit, 6D Drill Diameter Range 21.00-21.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

The CSJ Crown Drill Bit is a high-performance, indexable 6D deep-hole drilling solution designed for precision and speed. Featuring an advanced front-locking body, a secure side-locking drill tip, and integrated internal cooling, this tool ensures maximum stability, efficient chip evacuation, and extended tool life in high-speed operations.

Product Introduction

Engineered for demanding industrial applications, the CSJ Crown Drill Bit (6D) redefines high-speed, deep-hole drilling efficiency. It features an innovative front-locking body mechanism paired with a side-locking drill tip, delivering unparalleled clamping rigidity and minimal runout under high-load conditions.

With its specialized internal cooling system, the drill delivers coolant directly to the cutting edge, drastically reducing thermal buildup and ensuring seamless chip evacuation. The indexable insert design eliminates the need for regrinding, allowing for rapid tip replacement, minimized downtime, and highly cost-effective manufacturing workflows.

Product Parameters

Key Functions & Benefits (Product Action)

• High-Speed Deep-Hole Penetration: The 6D depth capability allows for deep-hole drilling while maintaining exceptional straightness and surface finish.

• Dual-Lock Stability: The synergy between the front-locking body and side-locking tip prevents insert movement, eliminating vibration and reducing the risk of tool breakage.

• Superior Thermal Management: Dual internal coolant holes flush out chips instantaneously and keep the cutting zone cool, preventing work hardening of the workpiece.

• Cost Efficiency: The indexable crown tip system allows operators to change worn cutting edges quickly without replacing the entire drill body.

Application Scenarios

The CSJ Crown Drill Bit is highly versatile and ideally suited for heavy-duty machining in the following sectors:

• Automotive Manufacturing: Drilling engine blocks, crankshafts, and heavy-duty chassis components.

• Aerospace & Defense: Precision deep-hole processing of high-strength alloys and titanium components.

• Mold & Die Industry: Machining complex ejector pin holes and deep water cooling channels.

• Energy & Power: Drilling tube sheets, heat exchangers, and heavy wind turbine flanges.

• Suitable Materials: Carbon steel, alloy steel, stainless steel, cast iron, and high-temperature superalloys.
