CSJ Crown Drill Bit, 6D Drill Diameter Range 27.00-27.99, 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, Ø27.00–27.99mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an advanced front-locking body design and integrated internal cooling, this side-locking drill tip system ensures maximum stability, efficient chip evacuation, and exceptional hole accuracy in demanding industrial applications.

Product Introduction

The CSJ Crown Drill Bit series represents the next generation of deep-hole drilling technology. Designed with a 6D length-to-diameter ratio, this tool is built to handle deep boring operations without sacrificing precision.

Its innovative front-locking body coupled with a side-locking drill tip mechanism allows for quick, secure insert replacements directly on the machine, drastically minimizing downtime. Equipped with dual internal cooling channels, it delivers coolant directly to the cutting edge, reducing thermal stress and ensuring rapid chip evacuation. Whether you are machining tough alloys or high-volume steel components, the CSJ Crown Drill delivers the rigidity and speed required for modern CNC manufacturing.

Product Parameters

Product Functions & Key Benefits

• High-Speed Deep Boring: The rigid 6D structure supports high feed rates and high-speed rotation during deep-hole operations.

• Superior Thermal Management: Internal cooling channels force coolant right to the cutting zone, preventing overheating and extending tool life.

• Enhanced Chip Evacuation: The combination of pressurized internal coolant and optimized flute geometry flushes chips out smoothly, preventing clogging and workpiece scratching.

• High-Precision Clamping: The hybrid front- and side-locking system ensures zero insert movement, resulting in excellent hole concentricity and surface finish.

• Cost-Effective Maintenance: Instead of replacing the entire drill body, users only need to index or replace the crown drill tip, significantly reducing tooling costs.

Applications & Target Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty machining environments:

• Target Industries: Automotive manufacturing, aerospace engineering, heavy machinery, oil & gas equipment, and mold/die making.

• Common Workpieces: Engine blocks, large flanges, hydraulic cylinders, tube sheets, and structural steel frames.

• Applicable Machinery: CNC Machining Centers, Boring Mills, Gantry Milling Machines, and Specialized Deep-Hole Drilling Machines.

• Compatible Materials: Carbon steels, alloy steels, stainless steels, and cast iron.
