CSJ Crown Drill Bit, 5D Drill Diameter Range 38.00-38.99, 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 (5D, Ø38.00–38.99mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an innovative front-locking body, a side-locking drill tip, and integrated internal cooling, it delivers exceptional stability, efficient chip evacuation, and prolonged tool life in demanding industrial applications.

Product Introduction

Take your deep-hole drilling operations to the next level with the CSJ Crown Drill Bit. Designed for precision and speed, this 5D indexable drill bridges the gap between solid carbide drills and traditional indexable drilling systems.

Its advanced front-locking body coupled with a side-locking drill tip guarantees maximum clamping rigidity, minimizing runout and vibration even at high speeds. Equipped with internal cooling channels, it delivers coolant directly to the cutting edge, drastically reducing thermal stress and ensuring seamless chip evacuation. Perfect for heavy-duty manufacturing, this tool ensures lower cost-per-hole and maximum productivity.

Product Functions & Key Benefits

• High-Speed Deep Drilling: The 5D capability allows for efficient, deep-hole processing without sacrificing speed or accuracy.

• Superior Clamping Stability: The dual mechanism (front-locking body + side-locking tip) prevents insert movement under heavy cutting loads.

• Advanced Thermal Management: Internal cooling channels blast coolant right at the cutting zone, extending tool life and preventing material hardening.

• Cost-Efficient Indexable Design: No need to regrind the whole drill bit—simply replace or rotate the crown insert, drastically reducing downtime and tool costs.

• Excellent Chip Evacuation: Optimized flute geometry combined with internal coolant ensures chips are flushed out quickly, preventing clogging.

Application Applications

The CSJ Crown Drill Bit is highly versatile and widely used across heavy industries, including:

• Industries: Aerospace, Automotive manufacturing, Mold & Die making, Heavy Machinery, Oil & Gas, and Power Generation.

• Applicable Machines: CNC Machining Centers, High-Speed Drilling Machines, Lathes, and Boring Machines.

• Workpiece Materials: Ideal for drilling Carbon Steel, Alloy Steel, Stainless Steel, Cast Iron, and high-strength alloys.
