The CSJ Crown Drill Bit (6D, Ø29.00-29.99mm) is a high-performance indexable insert drilling solution engineered for high-speed, deep-hole applications. Featuring an advanced front-locking body and an internal cooling system, this side-locking drill tip ensures exceptional chip evacuation, maximum rigidity, and superior hole accuracy in demanding industrial environments.
The CSJ Crown Drill Bit represents the next generation of deep-hole drilling technology. Designed with a robust 6D length-to-diameter ratio, it excels at drilling depths up to six times its diameter while maintaining impeccable straightness.
At its core is a sophisticated front-locking body mechanism paired with a secure side-locking drill tip. This dual-assurance design allows for rapid insert replacement directly on the machine, drastically reducing downtime. Equipped with dual internal cooling channels, the tool delivers high-pressure coolant straight to the cutting edge. This effectively lowers thermal stress, prevents chip packing, and significantly extends tool life during high-speed operations.

High-Efficiency Deep Drilling: The 6D capability allows for rapid, single-pass deep-hole drilling without the need for frequent pecking cycles.
Advanced Thermal Management: Internal cooling channels blast coolant directly at the cutting zone, reducing heat buildup and ensuring smooth chip evacuation.
Maximum Rigidity & Stability: The front-locking mechanism combined with the side-locking tip minimizes vibration, ensuring high-precision hole concentricity and excellent surface finish.
Cost-Effective Indexable Design: Eliminates the need for regrinding. When the crown/insert wears out, simply swap the tip to restore brand-new cutting performance instantly.
Automotive & Aerospace: Manufacturing of engine blocks, transmission shafts, and heavy-duty structural components.
Heavy Machinery & Mold Making: Drilling deep core fluid lines and ejector pin holes in large injection molds.
Energy & Power Generation: Processing of tube sheets, flanges, and high-pressure piping components.
Optimized for high-speed machining across a wide spectrum of materials, including:
Carbon Steel & Alloy Steel
Stainless Steel (SUS)
Cast Iron (GG/GGG)
High-Temperature Superalloys
