CSJ Crown Drill Bit, 6D Drill Diameter Range 14.0-14.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

High-performance CSJ Crown Drill Bit (6D) engineered for high-speed, deep-hole drilling. Featuring a 14.0–14.99mm diameter range, an advanced front-locking body, and internal cooling channels, this indexable insert / side-locking drill tip delivers exceptional chip evacuation, precision accuracy, and extended tool life in demanding industrial applications.

Product Introduction

The CSJ Crown Drill Bit represents the next generation of deep-hole drilling technology. Designed with a robust 6D length-to-diameter ratio, it effortlessly handles deep boring tasks while maintaining superior rigidity and minimal deflection.

Equipped with an innovative front-locking body mechanism and a side-locking drill tip, this indexable insert system allows for lightning-fast insert replacements directly on the machine, drastically reducing downtime. The integration of internal through-coolant holes ensures optimal cooling and lubrication directly at the cutting edge, effectively preventing heat buildup and ensuring flawless chip evacuation even at high cutting speeds.

Product Specifications (Parameters)

Product Functions & Key Benefits

• High-Speed Deep Boring: The 6D design enables deep-hole drilling up to six times the tool’s diameter without sacrificing precision or surface finish quality.

• Internal Cooling Technology: Delivers high-pressure coolant straight to the cutting zone, reducing thermal shock, extending tool life, and pushing chips out efficiently.

• Secure Double-Locking System: Combining a front-locking body with a side-locking tip ensures maximum stability under high-torque conditions, preventing insert displacement.

• Cost-Efficient Indexable Design: No need to regrind the entire tool; simply replace the crown drill tip when worn, saving tool costs and minimizing setup time.

Application Scenarios

The CSJ Crown Drill Bit is optimized for heavy-duty machining environments, including:

• Automotive Manufacturing: Drilling engine blocks, crankshafts, and powertrain components.

• Aerospace & Defense: Machining high-strength alloys and deep structural components.

• Heavy Machinery & Energy: Boring deep holes in wind turbine components, hydraulic cylinders, and valves.

• Die & Mold Making: Creating deep water cooling lines and ejector pin holes in mold bases.
