CSJ Crown Drill Bit, 4D Drill Diameter Range 14.00-14.99, 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 (4D) is a high-performance, indexable insert drilling solution engineered for precision high-speed deep-hole machining. Featuring a front-locking body design and advanced internal cooling channels, this side-locking drill tip system accommodates a diameter range of 14.00mm to 14.99mm, delivering exceptional chip evacuation and prolonged tool life in demanding environments.

Product Overview

The CSJ Crown Drill Bit series redefines deep-hole drilling efficiency. Built with a robust 4D depth-to-diameter ratio, this tool combines the rigidity of a solid carbide drill with the cost-effectiveness of an indexable insert system.

Its innovative front-locking body mechanism ensures maximum stability and quick insert replacement directly on the machine, minimizing downtime. Supported by a specialized side-locking drill tip, it eliminates micro-vibrations during high-speed rotations. Furthermore, the integrated internal cooling system delivers high-pressure coolant directly to the cutting edge, drastically reducing thermal stress and ensuring seamless chip flushing.

 Key Functions & Benefits

• High-Speed Deep-Hole Penetration: Achieves superior material removal rates (MRR) at a 4D depth without sacrificing hole straightness.

• Superior Thermal Management: Internal cooling channels lower cutting zone temperatures, preventing work hardening and extending tool longevity.

• Uncompromised Stability: The dual action of the front-locking body and side-locking tip prevents insert displacement under heavy axial and radial forces.

• Cost-Efficient Maintenance: Instead of replacing the entire drill body, users only need to swap the crown insert, significantly reducing tooling costs per hole.

Target Applications & Scenarios

This versatile tooling system is widely adopted across heavy manufacturing sectors, including Automotive, Aerospace, Mold & Die Making, and Heavy Machinery Production.

Common Machining Scenarios:

• Deep-Hole Boring: Ideal for creating engine blocks, hydraulic cylinders, and transmission shafts.

• High-Speed CNC Milling & Drilling: Optimized for modern CNC machining centers and high-speed lathes with thru-spindle coolant capabilities.

• Multi-Material Processing: Highly effective in drilling carbon steel, alloy steel, stainless steel, and cast iron.
