CSJ Crown Drill Bit, 6D Drill Diameter Range 25.00-25.99, 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-efficiency indexable insert drill engineered for high-speed, deep-hole drilling applications. Featuring a robust front-locking body and integrated internal cooling channels, it ensures optimal chip evacuation, reduced thermal buildup, and exceptional hole accuracy within the 25.00mm to 25.99mm diameter range. Equipped with a secure side-locking drill tip, this tool delivers maximum stability and extended tool life under heavy-duty machining conditions.

Product Introduction

Designed for modern CNC machining environments that demand both speed and precision, the CSJ 6D Crown Drill Bit redefines deep-hole drilling efficiency.

Unlike traditional twist drills, its indexable insert system eliminates the need for regrinding—simply index or replace the side-locking drill tip to maintain peak cutting performance. The 6D depth capability allows it to drill holes up to six times its diameter without sacrificing structural rigidity. With advanced internal coolant delivery pointing directly at the cutting edge, it significantly lowers friction, prevents chip clogging, and ensures a superior surface finish.

Product Specifications (Parameters)

Key Functions & Product Benefits (Product Action)

• High-Speed Deep Drilling: The 6D length-to-diameter ratio enables rapid, deep-hole penetration while maintaining strict straightness and dimensional tolerances.

• Efficient Chip Evacuation: Dual internal cooling channels flush chips out of the hole instantly, preventing tool breakage and recutting of chips.

• Rigid Tool Clamping: The combination of a front-locking body and a side-locking tip minimizes vibration, ensuring high stability during high-feed operations.

• Cost-Efficient Maintenance: The indexable crown system reduces downtime; users can replace worn tips quickly without removing the entire drill body from the machine tool holder.

Application Scenarios

The CSJ 6D Crown Drill Bit is highly versatile and optimized for heavy industries requiring deep-hole accuracy:

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

• Aerospace & Defense: Drilling structural aircraft components, landing gear parts, and high-strength alloy frames.

• Oil & Gas / Energy: Machining tube sheets for heat exchangers, valves, flanges, and drilling thick steel plates.

• Die & Mold Manufacturing: Creating deep cooling fluid lines or ejector pin holes in large mold bases.

• Compatible Materials: Excellent performance i
