CSJ Crown Drill Bit, 5D Drill Diameter Range 10.50-10.99, 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) 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 chip evacuation, precise hole accuracy, and extended tool life in demanding industrial applications.

Product Overview

The CSJ Crown 5D Indexable Insert Drill is designed to bridge the gap between solid carbide drills and traditional indexable drills. Its innovative front-locking body coupled with a side-locking drill tip ensures maximum rigidity and minimal runout during high-speed operations. Built for deep-hole drilling up to 5 times the diameter (5D), this tool features specialized internal cooling channels that deliver coolant directly to the cutting edge. This effectively lowers cutting temperatures, prevents thermal deformation, and forces chips out of the hole rapidly, ensuring a flawless surface finish.

Product Parameters

Key Functions & Benefits (Product Role)

• High-Speed Deep Drilling: Effortlessly achieves 5D deep-hole drilling at elevated RPMs without sacrificing stability.

• Superior Chip Evacuation: Dual internal cooling channels flush out metal chips continuously, preventing chip clogging and tool breakage.

• Quick-Change Efficiency: The front-locking and side-locking mechanism allows for rapid tip replacement directly on the machine, drastically reducing downtime.

• Cost-Effective Longevity: Instead of replacing the entire drill body, only the crown insert needs swapping, significantly lowering tooling costs per hole.

• Enhanced Hole Quality: Exceptional rigidity minimizes vibration, ensuring high-precision tolerance and excellent hole straightness.

Application Scenarios

• Industries: Automotive manufacturing, aerospace, heavy machinery, mold and die making, and energy/power generation.

• Equipment: Suitable for CNC machining centers, CNC lathes, milling machines, and specialized deep-hole drilling equipment.

• Target Materials: Ideal for high-efficiency drilling in carbon steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
