CSJ Crown Drill Bit, 6D 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

Product Short Description

The CSJ Crown Drill Bit is a high-performance, indexable deep-hole drilling solution designed for precision and speed. Featuring a front-locking body, a side-locking drill tip, and integrated internal cooling, this 6D drill delivers exceptional chip evacuation and stability for hole diameters ranging from 23.00mm to 23.99mm.

Product Introduction

Engineered for demanding industrial machining, the CSJ Crown Drill Bit represents the next generation of high-speed deep-hole drilling technology. It bridges the gap between solid carbide drills and traditional indexable drills.

With its advanced 6D length-to-diameter ratio, this tool is built to handle deep boring operations without sacrificing accuracy. The innovative front-locking body paired with a side-locking drill tip ensures maximum rigidity and quick insert replacements, minimizing downtime. Equipped with dual internal cooling channels, it delivers coolant directly to the cutting edge, drastically reducing thermal stress and ensuring flawless chip evacuation in deep cavities.

Product Parameters

Product Functions (Product Role)

• High-Speed Deep Boring: Efficiently executes deep-hole drilling up to 6 times the drill diameter ($6D$) at high RPMs.

• Superior Thermal Management: Internal cooling channels spray coolant directly at the cutting zone, preventing overheating and extending tool life.

• Rigid Vibration Dampening: The dual-locking mechanism (front and side) secures the crown insert, reducing chatter and ensuring high hole straightness.

• Cost-Efficient Machining: The indexable/replaceable tip design eliminates the need for regrinding; simply swap the worn crown tip to restore 100% cutting efficiency.

Application Scenarios

This industrial-grade drill bit is highly versatile and optimized for heavy-duty manufacturing sectors, including:

• Automotive Industry: Drilling engine blocks, crankshafts, and heavy powertrain components.

• Aerospace & Defense: Machining landing gear components and high-strength alloy structures.

• Mold & Die Making: Creating deep water/coolant lines in large injection molds.

• Heavy Machinery & Energy: Boring deep holes in wind turbine components, oil & gas piping, and hydraulic cylinders.

• Compatible Materials: Optimized for Carbon Steel, Alloy Steel, Cast Iron, Stainless Steel, and High-Temperature Alloys.
