CSJ Crown Drill Bit, 5D Drill Diameter Range 18.00-18.99, 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 (5D, 18.00–18.99mm) featuring a robust front-locking design and integrated internal cooling. Engineered for high-speed, high-precision deep-hole drilling, this indexable side-locking drill tip ensures maximum stability, efficient chip evacuation, and extended tool life in demanding industrial applications.

Product Introduction

The CSJ Crown Drill Bit represents the next generation of deep-hole drilling technology. Designed with a 5D structural depth capacity and a versatile 18.00–18.99mm diameter range, this tool bridges the gap between solid carbide drills and traditional indexable drills.

At its core is an innovative front-locking body mechanism combined with a side-locking drill tip, providing exceptional clamping rigidity that minimizes vibration at high speeds. Equipped with advanced internal cooling channels, it delivers coolant directly to the cutting edge, drastically reducing heat friction and ensuring flawless chip evacuation during continuous machining.

Product Parameters

Product Functions & Benefits (Product Role)

• High-Speed Deep Drilling: The 5D depth capacity allows for rapid, precise deep-hole drilling without compromising structural integrity or hole straightness.

• Superior Clamping Stability: The dual action of the front-locking body and side-locking tip prevents insert displacement, even under high torque and heavy feed rates.

• Advanced Thermal Management: Internal cooling channels force coolant directly to the cutting zone, preventing thermal deformation of the workpiece and prolonging insert life.

• Cost-Efficient Indexable Design: Instead of replacing the entire drill body, users only need to swap or index the crown tip, drastically reducing tooling costs and machine downtime.

• Excellent Surface Finish: High rigidity combined with optimal chip evacuation ensures a clean, burr-free surface finish inside the drilled hole.

Application Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty manufacturing environments, including:

• Automotive Industry: Drilling engine blocks, crankshafts, and heavy-duty transmission components.

• Aerospace & Defense: Machining high-strength alloys and structural components requiring strict tolerances.

• Mold & Die Manufacturing: Creating deep core cooling channels and ejector pin holes in heavy molds.

• Heavy Machinery & Energy: Processing tube sheets for heat exchangers, wind turbine components, and oil/gas drilling equipment.

• Compatible Materials: Highly effective on carbon steel, alloy steel, stainless steel, cast iron, and high-temperature exotic alloys.
