CSJ Crown Drill Bit, 5D 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

Product Description

CSJ Crown Drill Bit (5D, 33.00–33.99mm) Engineered for high-efficiency machining, the CSJ Crown Drill Bit features an innovative front-locking body and an internal cooling system. Designed specifically for high-speed, deep-hole drilling, this indexable side-locking drill tip delivers exceptional stability, rapid chip evacuation, and superior hole accuracy in demanding industrial applications.

Product Introduction

The CSJ Crown Drill Bit is a next-generation indexing drilling solution engineered to bridge the gap between solid carbide drills and traditional indexable insert drills. With a drilling depth of 5D and a versatile diameter range of 33.00mm to 33.99mm, it offers a highly rigid structural design.

The advanced front-locking mechanism ensures quick and precise insert replacement directly on the machine, drastically reducing downtime. Equipped with dual internal cooling channels, it delivers coolant directly to the cutting edge, effectively reducing thermal stress and ensuring seamless chip evacuation during high-speed operations.

Product Functions & Benefits

• High-Speed Deep-Hole Penetration: The 5D depth capability allows for rapid, deep-hole drilling without compromising structural rigidity or centerline accuracy.

• Revolutionary Front-Locking System: Enables fast tip replacement without removing the tool body from the holder, maximizing machine uptime and operational efficiency.

• Advanced Internal Cooling: Dual internal coolant holes lower cutting zone temperatures, significantly extending tool life and preventing chip clogging.

• Cost-Efficient Indexable Design: Rather than replacing the entire drill body, users only need to replace or index the crown insert, drastically reducing tooling costs per hole.

• Excellent Surface Finish: High-rigidity body minimizes vibration, delivering superior hole tolerance and surface finish.

Application Scenarios

The CSJ Crown Drill Bit is optimized for heavy-duty CNC machining, gantry milling, and specialized drilling machines across various industries:

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

• Aerospace & Defense: Machining structural components and high-strength alloy parts.

• Energy & Power Generation: Deep-hole drilling for tube sheets in heat exchangers, wind turbine hubs, and oil/gas valves.

• Heavy Machinery Manufacturing: Ideal for manufacturing hydraulic cylinders, mold bases, and large-scale mechanical frameworks.
