Product Short Description

The CSJ Crown Drill Bit (5D) is a high-performance, indexable insert drilling tool designed for high-speed, deep-hole applications. Featuring a front-locking body design with integrated internal cooling channels, it delivers exceptional stability, chip evacuation, and precision for hole diameters ranging from 35.00mm to 35.99mm.

Product Introduction

Engineered for demanding industrial machining, the CSJ Crown Drill Bit (5D) combines the rigidity of a solid carbide drill with the cost-efficiency of an indexable system. Its advanced front-locking mechanism ensures rapid and secure insert changes directly on the machine, minimizing downtime. With a 5D drilling depth capacity (5 times the drill diameter) and a robust side-locking drill tip, this tool is optimized to withstand high torsional forces while maintaining superior hole accuracy and surface finish during high-speed operations.

Key Product Features & Functions

High-Speed Deep-Hole Drilling (5D): Enables stable drilling up to 5 times the tool diameter without compromising structural rigidity or hole straightness.
Internal Cooling System: Dual internal coolant holes deliver high-pressure fluid directly to the cutting edge, drastically reducing thermal buildup and ensuring seamless chip evacuation.
Front-Locking System: Allows users to replace the crown drill tip quickly without removing the entire drill body from the holder, maximizing productivity.
Side-Locking Drill Tip: Provides maximum gripping force and torque transmission, preventing insert movement under heavy chip loads.
Cost Efficiency: Only the worn crown tip needs replacement, significantly lowering tool management costs compared to solid carbide drills.

Application Scenarios

This versatile drilling system is widely used across heavy industries requiring high-precision, deep-hole manufacturing:

Automotive Industry: Machining engine blocks, crankshafts, and heavy-duty transmission components.
Aerospace & Defense: Drilling structural components, landing gears, and high-strength alloy parts.
Mold & Die Manufacturing: Creating deep core cooling channels and ejector pin holes in large mold bases.
Heavy Machinery & Energy: Processing wind turbine components, pressure vessels, and large hydraulic cylinders.
Compatible Materials: Optimally suited for Steel (P), Stainless Steel (M), Cast Iron (K), and High-Temperature Alloys (S).
