CSJ Crown Drill Bit, 4D Drill Diameter Range 19.00-19.99, 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 is a high-performance, 4D indexable insert drill featuring a front-locking body and internal cooling. Engineered for high-speed, deep-hole drilling, it combines a precision side-locking drill tip with a 19.00–19.99 mm diameter range to deliver exceptional stability, efficient chip evacuation, and prolonged tool life in demanding machining environments.

Product Introduction

The CSJ Crown Drill Bit (4D Series) represents the next generation of high-efficiency hole-making technology. Designed specifically for deep-hole operations, this tool features an advanced Front-Locking Body paired with a secure Side-Locking Drill Tip mechanism. This dual-assurance design guarantees maximum rigidity and minimizes runout even under extreme cutting forces.

Equipped with specialized Internal Cooling channels, the drill delivers high-pressure coolant directly to the cutting edge. This effectively lowers cutting temperatures, reduces thermal deformation, and forces chips out of deep holes seamlessly. Whether you are running high-speed CNC machining or heavy-duty drilling, the CSJ Crown Drill delivers the speed, accuracy, and cost-per-hole economy your production line demands.

Product Parameters

Product Functions & Features

• High-Speed Deep-Hole Penetration: Optimized 4D length-to-diameter ratio allows for rapid, deep-hole drilling without sacrificing structural integrity.

• Dual-Locking Stability: The combination of a front-locking body and side-locking tip ensures the insert stays perfectly seated, preventing micro-vibrations and improving surface finish.

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

• Cost-Efficient Indexable Design: Easily replace or rotate the drill tip/inserts without discarding the entire drill body, significantly reducing tooling overhead.

• Excellent Chip Evacuation: Wide, polished flutes work in tandem with internal coolant to evacuate chips effortlessly, preventing catastrophic tool breakage.
