CSJ Crown Drill Bit, 5D Drill Diameter Range 37.00-37.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

High-performance CSJ Crown Drill Bit featuring a 5D drilling depth and a 37.00–37.99 mm diameter range. Designed with a front-locking body and an advanced internal cooling system, this indexable side-locking drill tip ensures maximum stability, superior chip evacuation, and exceptional efficiency for high-speed, deep-hole drilling operations.

Product Introduction

The CSJ Crown Drill Bit is a premium indexable insert drilling solution engineered for demanding industrial machining. Combining the rigidity of a solid carbide drill with the cost-efficiency of an indexable system, it utilizes a secure front-locking mechanism and side-locking drill tip to eliminate vibration during high-speed operations. Equipped with internal coolant channels, it delivers precise coolant directly to the cutting edge, drastically reducing thermal wear and extending tool life. This is the ultimate tool for achieving flawless precision in deep-hole drilling applications.

Product Specifications (Parameters)

Product Features & Functions (Product Roles)

• High-Speed Deep Hole Drilling: Optimized for 5D depth capabilities, ensuring straight, accurate holes without sacrificing speed.

• Internal Cooling System: Dual internal coolant holes flush out metal chips efficiently and reduce heat buildup, preventing tool breakage and workpiece deformation.

• Dual-Locking Stability: The combination of a front-locking body and side-locking tip provides maximum clamping force, minimizing radial runout at high RPMs.

• Cost-Effective Indexable Design: Easily replace the crown drill tip instead of the entire tool body, significantly lowering tooling costs and reducing machine downtime.

Application Scenarios

• Heavy Machinery Manufacturing: Perfect for drilling large-diameter, deep holes in structural frames, hydraulic cylinders, and heavy equipment parts.

• Automotive & Aerospace Engineering: Ideal for high-precision machining of engine blocks, transmission components, and landing gear parts.

• Mold & Die Industry: Efficiently handles deep cooling line drillings in complex mold bases.

• Compatible Materials: Excellent performance across a wide range of materials, including carbon steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
