CSJ Crown Drill Bit, 4D Drill Diameter Range 22.00-22.99, 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 is a high-performance, indexable insert drill designed for high-speed, deep-hole drilling. Featuring a 4D depth capability and a secure front-locking body with a side-locking drill tip, this tool integrates advanced internal cooling to ensure maximum chip evacuation, reduced thermal stress, and exceptional hole accuracy in demanding industrial applications.

Product Introduction

Engineered for precision and high efficiency, the CSJ Crown Drill Bit bridges the gap between solid carbide drills and traditional indexable drills. It features an innovative front-locking clamping mechanism combined with a side-locking drill tip, ensuring maximum stability and repeatability during high-feed operations. With its internal through-coolant channels delivering fluid directly to the cutting edge, it significantly extends tool life while preventing chip clogging in deep-hole processing.

Technical Parameters

Product Functions & Benefits

• High-Speed Deep Hole Drilling: The 4D length-to-diameter ratio allows for rapid, deep penetration without sacrificing rigidity or hole straightness.

• Advanced Chip Evacuation: Dual internal cooling channels deliver high-pressure coolant directly to the cutting zone, flushing out chips instantly and reducing heat buildup.

• Secure Dual-Locking Mechanism: The combination of a front-locking body and side-locking tip provides superior gripping force, eliminating tip movement and vibration under heavy loads.

• Cost-Efficient Indexable Design: No need to regrind the entire tool body. Simply replace the crown insert/tip when worn, drastically reducing downtime and tooling costs.

Target Applications & Industry Scenarios

• Machinery Manufacturing: Perfect for drilling heavy-duty components, hydraulic cylinders, and large baseplates.

• Automotive & Aerospace: Ideal for precision engine block processing, structural frames, and landing gear components where high tolerance is required.

• Mold & Die Industry: Widely used for creating deep coolant lines and ejector pin holes in large injection molds.

• Energy & Power Generation: Highly effective for tube sheet drilling in heat exchangers and heavy flange processing.

• Compatible Materials: Optimized for structural steel, carbon steel, alloy steel, cast iron, and stainless steel.
