Product Short Description

The CSJ Crown Drill Bit (4D, Ø25.00–25.99mm) is a high-performance indexable insert/side-locking drill designed for high-speed, deep-hole drilling. Featuring an advanced front-locking body design and internal cooling channels, it delivers exceptional precision, efficient chip evacuation, and extended tool life in demanding industrial applications.

Product Introduction

Engineered for maximum stability and efficiency, the CSJ Crown Drill Bit is a premier solution for high-speed deep-hole machining. This 4D length-to-diameter ratio drill features a robust front-locking body structure combined with a secure side-locking drill tip/indexable insert system, ensuring rigid clamping and minimal runout under heavy cutting loads.

Equipped with state-of-the-art internal cooling technology, the drill delivers coolant directly to the cutting edge, drastically reducing thermal stress and ensuring seamless chip evacuation. This eliminates the common bottlenecks of deep-hole drilling, allowing for continuous, high-speed operations without compromising surface finish or accuracy.

Key Benefits & Functions (Product Role)

High-Precision Deep-Hole Machining: The 4D reach allows for deep penetration while maintaining strict dimensional accuracy and straightness.
Superior Thermal Management: Dual internal cooling channels flush out heat instantly, preventing workpiece deformation and protecting the cutting edge.
Rigid Side-Locking Design: The combination of front-locking and side-locking mechanisms ensures zero insert movement, reducing vibration and preventing premature tool failure.
Cost-Efficient Indexable System: Instead of replacing the entire drill body, only the crown/insert tip needs to be replaced or indexed, drastically lowering tooling costs per hole.
Excellent Chip Control: Optimized flute geometry paired with internal coolant pressure forces chips out quickly, preventing chip clogging and tool breakage.

Application Scenarios

The CSJ Crown Drill Bit is widely utilized across heavy manufacturing industries where deep, precise holes are required:

Automotive Industry: Machining engine blocks, transmission shafts, and heavy-duty powertrain components.
Aerospace & Defense: Drilling structural components, landing gears, and specialized alloy parts.
Mold & Die Manufacturing: Creating deep core cooling channels and ejector pin holes in large mold bases.
Heavy Machinery & Energy: Processing tube sheets for heat exchangers, wind turbine components, and oil/gas drilling equipment.
Compatible Materials: Ideal for high-efficiency drilling in carbon steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
