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 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.
