Product Functions & Benefits

High-Speed Deep-Hole Drilling: Easily achieves a 4D drilling depth with stable performance and minimal deflection.
Internal Cooling Technology: The specialized through-coolant channels flush out chips instantly and lower cutting temperatures, preventing premature insert wear.
Rigid Locking System: The combination of a front-locking body and a side-locking tip provides maximum structural integrity, ensuring high repeatability and excellent surface finish.
Cost-Efficient Indexable Design: Eliminates the need for regrinding. Simply index or replace the crown tip to maintain optimal cutting edge sharpness, reducing downtime.

Target Applications & Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty manufacturing sectors, including:

Automotive & Aerospace: Drilling engine blocks, transmission components, and structural frames.
Mold & Die Manufacturing: Creating deep core cooling channels and guide pin holes with strict tolerances.
