CSJ Crown Drill Bit, 4D Drill Diameter Range 21.00-21.99, 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 (4D, ∅21.00–21.99mm) is a high-performance indexable drilling solution engineered for high-speed, deep-hole applications. Featuring an advanced front-locking body and integrated internal cooling channels, this side-locking drill tip system ensures maximum stability, efficient chip evacuation, and exceptional hole accuracy in demanding industrial environments.

 Product Overview

Designed for high-efficiency machining, the CSJ Crown Drill Bit Bridges the gap between solid carbide drills and traditional indexable drills. Its innovative front-locking, side-locking crown tip design allows for quick tool changes directly on the machine, drastically reducing downtime.

Equipped with a 4D depth capability and thru-spindle internal cooling, it effectively lowers cutting temperatures and flushes out chips instantly, preventing tool wear and workpiece damage during high-speed operations. The robust body ensures excellent rigidity, reducing vibration and ensuring high-precision, straight deep-hole drilling.

Product Parameters

 Key Functions & Features

• High-Speed Deep-Hole Drilling: The 4D length-to-diameter ratio enables swift, deep penetration while maintaining excellent hole straightness and surface finish.

• Advanced Internal Cooling: Delivers high-pressure coolant directly to the cutting edge, significantly extending tool life and ensuring optimal chip evacuation.

• Secure Front & Side-Locking Mechanism: The combination of a front-locking body and a side-locking tip provides superior clamping rigidity, preventing insert movement under heavy cutting loads.

• Cost-Efficient Indexable System: No need to regrind the whole tool; simply replace the crown drill tip, reducing inventory costs and maximizing productivity.
