CSJ Crown Drill Bit, 5D Drill Diameter Range 12.00-12.99, 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 (5D, Ø12.00–12.99mm) is a high-performance indexable drilling tool engineered for high-speed, deep-hole operations. Featuring an advanced front-locking body and integrated internal cooling, this side-locking drill tip system ensures maximum stability, efficient chip evacuation, and exceptional hole accuracy in demanding industrial applications.

Product Introduction

Unlock next-level machining efficiency with the CSJ Crown Drill Bit. Designed specifically for 5D deep-hole drilling within a precise 12.00mm to 12.99mm diameter range, this tool combines the economic benefits of an indexable insert drill with the rigid performance of solid carbide.

Its innovative front-locking design allows for quick, seamless drill tip replacements directly on the machine, drastically minimizing downtime. Enhanced with a robust side-locking mechanism and internal coolant thru-holes, it effectively manages heat and evacuates chips, ensuring pristine surface finishes and extended tool life even under high-speed parameters.

Technical Parameters

Key Functions & Benefits (Product Action)

• High-Speed Deep-Hole Penetration: Effortlessly achieves stable 5D deep-hole drilling at high feed rates without sacrificing accuracy.

• Internal Coolant Delivery: Directs coolant straight to the cutting edge to reduce thermal shock, minimize friction, and forcefully flush out chips.

• Rigid Front & Side Locking: The specialized front-locking body coupled with a side-locking tip prevents deflection and vibration, ensuring tight hole tolerances.
