CSJ Crown Drill Bit, 5D Drill Diameter Range 32.00-32.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

High-performance CSJ Crown Drill Bit (5D, Ø32.00–32.99mm) featuring an advanced front-locking body and internal cooling system. Engineered for high-speed, stable deep-hole drilling with indexable side-locking inserts. Deliver maximum chip evacuation and precision in heavy-duty industrial applications.

Product Introduction

The CSJ Crown Drill Bit represents the next generation of high-efficiency deep-hole drilling technology. Designed with a robust 5D aspect ratio, this tool handles depths up to five times its diameter with exceptional rigidity.

Its innovative front-locking mechanism paired with a side-locking drill tip guarantees secure insert seating, minimizing vibration and runout even under high-feed conditions. Equipped with precision internal cooling channels, it delivers coolant directly to the cutting edge, drastically reducing thermal stress, accelerating chip evacuation, and extending tool life. Whether you are running high-speed CNC machining or heavy-duty manual drilling, the CSJ Crown Drill delivers unmatched accuracy and throughput.

Product Parameters

Product Functions & Benefits

• High-Speed Deep Hole Penetration: Optimized 5D geometry allows for rapid, continuous drilling up to 5x diameter without the need for frequent pecking cycles.

• Superior Thermal Management: Dual internal coolant holes flush out heat instantly from the cutting zone, preventing work hardening and insert chipping.

• Ultimate Rigidity & Security: The combination of a front-locking body and side-locking tip ensures the insert remains perfectly stationary under intense axial and radial forces.

• Cost-Efficient Indexable Design: Easily replace worn crown tips or indexable inserts without changing the entire drill body, significantly reducing tooling costs per hole.

Applications & Scenarios

The CSJ Crown Drill Bit is highly versatile and ideally suited for modern manufacturing environments requiring deep, high-precision holes:

• Heavy Machinery & Automotive: Drilling engine blocks, transmission shafts, and heavy-duty chassis components.

• Mold & Die Industry: Creating deep coolant lines, core holes, and ejector pin holes in hardened mold steels.

• Energy & Power Generation: Machining tube sheets for heat exchangers, turbines, and wind power flanges.

• Aerospace & Oil/Gas: Drilling high-strength structural parts, manifolds, and valves made of tough alloys.

• Compatible Equipment: Ideal for CNC Machining Centers, Lathes with live tooling, Boring Machines, and Radial Drilling Machines with internal coolant capabilities.
