CSJ Crown Drill Bit,10D Drill Diameter Range 38.00-38.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

1. Short Description

The CSJ 10D Front-Locking Crown Drill Bit (Ø38.00–38.99 mm) is designed for high-efficiency deep-hole drilling in demanding industrial applications. Featuring internal coolant channels for superior chip evacuation and heat dissipation, alongside a robust front-locking indexable design, it delivers outstanding accuracy, extended tool life, and high-speed drilling performance.

2. Product Overview (Product Introduction)

Engineerd for demanding industrial machining, the CSJ 10D Series Front-Locking Crown Drill Bit provides an exceptional solution for deep-hole drilling with a diameter range of Ø38.00 mm to Ø38.99 mm.

Utilizing a high-precision front-locking indexable insert structure (side-locking tip setup), this drill body allows rapid tip replacement directly on the spindle without removing the entire tool holder—minimizing downtime and boosting productivity. The integrated internal cooling system delivers high-pressure coolant straight to the cutting edge, effectively preventing thermal deformation and flushing out chips during high-depth 10D operations. Built from high-strength alloy steel with excellent rigidity, the CSJ crown drill ensures vibration-free stability, superior surface finishes, and repeatable precision across heavy-duty production runs.

4. Key Functions & Benefits (Product Action)

• High-Speed Deep-Hole Drilling (10D Depth Ratio): Achieves deep-hole penetration up to 10 times the drill diameter without sacrificing straightness or hole accuracy.

• Rapid Tool Replacement (Front-Locking System): The front/side-locking design allows quick and secure tip changes directly on the machine, reducing setup times and operating costs.

• Effective Chip Evacuation & Thermal Control: Through-tool internal coolant channels supply high-pressure fluid directly to the cutting zone, lowering thermal stress and continuously clearing chips from deep cavities.

• Exceptional Rigidity & Anti-Vibration: Optimized body structure absorbs high-torque cutting forces, reducing chatter and maintaining high hole surface finish quality.

• Cost-Effective Indexable Design: Eliminates the need to replace or re-sharpen the entire drill body; simply replace the worn insert tip.

5. Applications & Use Cases (Application Scenarios)

• Heavy Machinery & Equipment Manufacturing: Drilling structural holes in large baseplates, frames, and thick structural steel.

• Mold & Die Industry: High-speed machining of deep cooling water channels and ejector pin holes in large injection molds and forging dies.

• Wind Power & Energy Sector: Hole processing for wind turbine flanges, gearboxes, steam turbine components, and oilfield drilling hardware.

• Pressure Vessels & Heat Exchangers: Drilling thick tube sheets, boiler plates, and high-pressure fluid manifolds.

• Automotive & Aerospace Sub-Components: Precision deep-hole drilling for heavy vehicle axles, engine blocks, and structural aircraft components.

• Machine Compatibility: Suitable for CNC Machining Centers (VMC/HMC), CNC Lathes, Gantry Milling Machines, and Heavy-Duty Deep-Hole Drilling Equipment.
