CSJ Crown Drill Bit, 6D Drill Diameter Range 18.00-18.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

The CSJ Crown Drill Bit (6D) is a high-performance indexable insert drill engineered for high-speed, deep-hole machining. Featuring an advanced front-locking body, a versatile 18.00–18.99mm diameter range, and integrated internal cooling, this side-locking drill tip system ensures exceptional chip evacuation, maximum tool rigidity, and superior hole accuracy in demanding industrial applications.

Product Overview

The CSJ Crown Drill Bit series redefines efficiency in deep-hole drilling technology. Built for heavy-duty manufacturing, its 6D length-to-diameter ratio allows for deep penetration without sacrificing stability.

The innovative front-locking body coupled with a side-locking drill tip ensures rapid, secure insert replacement directly on the machine, drastically minimizing downtime. Equipped with dual internal coolant channels, it delivers pressurized coolant straight to the cutting edge, effectively reducing thermal stress and ensuring seamless chip flushing.

Product Parameters

Key Features & Benefits (Product Action)

• High-Speed Deep-Hole Efficiency: The 6D capability allows for high-feed drilling in deep cavities while maintaining strict dimensional tolerances.

• Advanced Internal Cooling: Dual internal coolant holes lower cutting temperatures at the contact zone, drastically extending tool and insert life.

• Rigid Front & Side Locking: The hybrid front-locking body and side-locking tip eliminate micro-vibrations, preventing tool deflection and ensuring excellent surface finish.

• Cost-Effective Indexable Design: No need to regrind the entire drill; simply swap out the precision crown insert to maintain a brand-new cutting edge, reducing tooling costs.
