$322.0000

Product Overview

Short Description

The CSJ Crown Drill Bit is a high-performance, 6D indexable insert drill engineered for high-speed, deep-hole drilling. Featuring a precise front-locking body, a versatile side-locking drill tip, and an advanced internal cooling system, it delivers exceptional stability, superior chip evacuation, and extended tool life across a drill diameter range of 11.50–11.99 mm.

Product Introduction

Designed to meet the rigorous demands of modern CNC machining, the CSJ Crown Drill Bit represents the next generation of deep-hole drilling technology. Its 6D aspect ratio allows for deep penetration without sacrificing accuracy. The innovative front-locking mechanism ensures maximum rigidity and minimal runout, while the side-locking drill tip allows for quick, seamless insert replacements. Equipped with targeted internal cooling channels, this tool effectively dissipates heat directly at the cutting edge, preventing thermal deformation and ensuring continuous, high-efficiency production.

Key Product Functions (Product Action)

High-Speed Deep Drilling: Effortlessly achieves 6D depth placement at elevated RPMs and feed rates.
Active Thermal Management: Delivers high-pressure coolant directly to the cutting zone via internal channels to flush out chips and reduce friction.
Rigid Clamping: The dual action of the front-locking body and side-locking tip eliminates vibration, ensuring perfect hole cylindricity and surface finish.
Cost-Efficient Indexing: Allows operators to replace or index only the worn crown/tip rather than the entire drill body, drastically reducing tooling costs.
