CSJ Crown Drill Bit, 6D Drill Diameter Range 33.00-33.99, 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 (6D) is a high-performance, indexable deep-hole drilling solution designed for diameter ranges of 33.00mm to 33.99mm. Featuring an advanced front-locking body design and integrated internal cooling channels, this tool delivers exceptional stability, rapid chip evacuation, and prolonged tool life during high-speed machining operations.

Product Introduction

Engineered for demanding industrial applications, the CSJ Crown Drill Bit combines the precision of a solid carbide drill with the cost-efficiency of an indexable system. Its specialized 6D drilling depth capability allows for deep-hole processing up to six times the drill’s diameter without sacrificing accuracy.

The innovative front-locking body mechanism paired with a secure side-locking drill tip guarantees maximum rigidity, eliminating vibration even under high-torque conditions. Equipped with state-of-the-art internal cooling (through-coolant) channels, it delivers coolant directly to the cutting edge, drastically reducing thermal buildup and ensuring seamless chip evacuation.

Technical Parameters

Product Functions & Benefits

• High-Speed Deep-Hole Penetration: Achieves stable 6D deep-hole drilling at elevated feed rates and cutting speeds.

• Superior Thermal Management: Dual internal cooling channels flush out chips instantly and lower cutting zone temperatures to prevent premature insert wear.

• Rapid Tool Changes: The front-locking and side-locking design allows operators to replace the drill tip directly on the machine, significantly minimizing downtime.

• Exceptional Hole Quality: High structural rigidity prevents tool deflection, ensuring excellent hole cylindricity, surface finish, and dimensional tolerance.

• Cost Efficiency: Instead of replacing the entire drill body, only the crown insert needs swapping when worn, drastically reducing tooling costs per hole.

Application Scenarios

This heavy-duty drilling system is ideally suited for high-precision, high-efficiency machining across various industries, including:

• Automotive & Aerospace: Drilling deep fluid channels, engine blocks, and structural aircraft components.

• Heavy Machinery & Energy: Processing tube sheets in heat exchangers, wind turbine parts, and oil/gas valve bodies.

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

• Compatible Materials: Optimized for Medium-to-High Carbon Steels, Alloy Steels, Cast Iron, Stainless Steel, and High-Temperature Alloys.
