CSJ Crown Drill Bit, 6D Drill Diameter Range 11.00-11.49, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

The CSJ Crown Drill Bit (6D, $\varnothing$ 11.00–11.49 mm) is a high-performance 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 rigidity, efficient chip evacuation, and exceptional hole accuracy in demanding industrial applications.

Product Introduction

Unlock superior drilling efficiency with the CSJ Crown Drill Bit series. Designed specifically for high-speed deep-hole operations up to a 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 pressurized coolant straight to the cutting edge, effectively reducing thermal stress and ensuring smooth chip evacuation even in deep cavities.

Product Parameters

Product Functions & Benefits

• High-Speed Deep Drilling: Easily achieves stable 6D deep-hole drilling at high feed rates without sacrificing precision.

• Excellent Thermal Management: Dual internal cooling holes flush out heat instantly, prolonging tool life and preventing work-hardening of the workpiece.

• Rigid Front-Locking Design: The secure front-locking and side-locking mechanism eliminates vibration, delivering excellent surface finish and strict hole tolerance.

• Cost-Efficient Insert System: No need to replace the entire drill body; simply swap the indexable crown tip, significantly reducing tooling costs per hole.

Application Scenarios

This industrial-grade drill bit is ideal for heavy-duty manufacturing sectors requiring precise deep-hole machining:

• Automotive Industry: Drilling engine blocks, crankshafts, and transmission components.

• Aerospace & Defense: Machining high-strength alloys, landing gear components, and structural frames.

• Mold & Die Making: Creating deep coolant lines, ejector pin holes, and core cavities.

• General Engineering: High-efficiency batch drilling in steel, stainless steel, cast iron, and exotic alloys on CNC machining centers and lathe machines.
