Product Short Description

The CSJ Crown Drill Bit (6D, Ø9.00–9.49mm) is a premium indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an advanced front-locking body and integrated internal cooling, this side-locking drill tip system ensures maximum stability, exceptional chip evacuation, and superior hole accuracy in demanding industrial applications.

Product Introduction

Take your deep-hole drilling efficiency to the next level with the CSJ Crown Drill Bit. Designed with a robust 6D depth-to-diameter ratio, this tool bridges the gap between solid carbide drills and traditional indexable drills.

Its innovative front-locking body paired with a side-locking drill tip allows for quick, seamless insert replacements directly on the machine, drastically minimizing downtime. Equipped with dual internal cooling channels, it delivers high-pressure coolant straight to the cutting edge, effectively reducing thermal stress and ensuring smooth chip evacuation during high-speed operations.

Product Functions & Key Benefits

High-Speed Deep-Hole Penetration: The 6D reach allows for deep-hole drilling while maintaining rigid stability and high feed rates.
Superior Thermal Management: Internal cooling channels blast coolant directly at the cutting zone, extending tool life and preventing work-hardening of the material.
Rigid Clamping & High Accuracy: The unique combination of a front-locking body and side-locking tip eliminates deflection, ensuring excellent hole straightness and surface finish.
Cost-Efficient Indexable Design: No need to regrind the whole tool—simply swap out the crown insert when worn out, significantly lowering your cost-per-hole.

Application Scenarios

This high-performance drill bit is ideal for heavy-duty manufacturing sectors requiring precise deep-hole machining, including:

Automotive Industry: Drilling engine blocks, crankshafts, and transmission components.
Aerospace & Defense: Precision machining of high-strength alloy structures and landing gear parts.
Mold & Die Making: Creating deep water cooling lines and ejector pin holes in molds.
General Engineering: Perfect for CNC machining centers, multitasking machines, and specialized deep-hole drilling equipment handling steel, stainless steel, cast iron, and exotic alloys.
