CSJ Crown Drill Bit, 7D Drill Diameter Range 23.00-23.99, 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 (7D, Ø23.00–23.99mm) is a high-performance indexable tooling solution designed for deep-hole drilling up to seven times the drill diameter. Featuring a rigid front-locking head mechanism and integrated internal cooling channels, it ensures superior chip evacuation, exceptional hole accuracy, and maximum productivity in high-speed metalworking.

Product Overview

Designed for heavy-duty industrial applications, the CSJ Crown Drill Bit combines the speed and rigidity of solid carbide drills with the cost efficiency of indexable tooling.

Its advanced front-locking body allows quick and secure tip changes directly on the machine, minimizing downtime. Coupled with internal high-pressure coolant channels, it directs coolant straight to the cutting edge, breaking chips efficiently and preventing heat build-up during deep-hole penetration ($7\times D$). Whether machining tough steels, stainless alloys, or cast iron, the CSJ Crown Drill delivers high penetration rates, smooth surface finishes, and consistent tool life.

Technical Specifications

Product Functions & Benefits

• High-Speed Deep-Hole Drilling: Effortlessly drills deep holes ($7\times D$) in a single pass without needing frequent pecking cycles.

• Efficient Heat & Chip Evacuation: Internal coolant channels flush chips out rapidly and maintain a lower cutting temperature, dramatically extending tool life.

• Quick-Change Front Locking: The front-locking mechanism enables rapid head replacement without removing the tool holder from the spindle, cutting setup time significantly.

• Superior Hole Precision: Rigid body construction reduces vibration and deflection, ensuring excellent straightness, concentricity, and fine surface finishes.

• Cost Efficiency: Swap out only the worn crown insert rather than replacing the entire drill body.
