CSJ Crown Drill Bit, 4D Drill Diameter Range 24.00-24.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

The CSJ Crown Drill Bit (4D) is a high-performance, indexable front-locking drill body engineered for high-speed, deep-hole drilling. Featuring advanced internal cooling and a secure side-locking drill tip mechanism, it delivers exceptional stability, superior chip evacuation, and precision for hole diameters ranging from 24.00mm to 24.99mm.

Product Introduction

Engineered for demanding industrial machining, the CSJ Crown Drill Bit combines the cost-efficiency of indexable inserts with the rigid performance of solid carbide drills. Its 4D usable length allows for deep-hole drilling up to four times the drill’s diameter.

The innovative front-locking body coupled with a side-locking drill tip ensures rapid insert changes directly on the machine, drastically minimizing downtime. Equipped with dual internal cooling channels, this tool channels high-pressure coolant straight to the cutting edge, effectively reducing thermal stress and ensuring seamless chip evacuation in heavy-duty operations.

Product Parameters (Specifications)

Product Benefits & Functions (Product Role)

• High-Speed Deep Drilling: Optimized 4D geometry allows for high-feed rate drilling in deep holes without compromising structural rigidity.

• Superior Thermal Management: Internal cooling channels deliver coolant precisely to the cutting zone, extending tool life and preventing workpiece deformation.

• Maximum Rigidity & Accuracy: The dual front-locking and side-locking design eliminates micro-vibrations, ensuring excellent hole cylindricality and surface finish.

• Cost & Time Efficiency: No need to replace the entire drill body; simply swap the indexable crown tip. Fast replacement reduces setup times and overhead costs.
