CSJ Crown Drill Bit, 7D Drill Diameter Range 10.00-10.49, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

High-performance indexable insert drill featuring a front-locking system and internal cooling, specifically engineered for stable and precise deep-hole drilling up to 7D depth within a 10.00–10.49 mm diameter range.

Product Introduction

The CSJ Crown Drill Bit is a premium indexable drilling solution designed for heavy-duty, high-speed deep-hole operations. Engineered with a robust front-locking mechanism and a secure side-locking drill tip design, it ensures maximum stability, repeatable precision, and effortless head replacements without removing the drill body from the machine.

Equipped with optimized internal cooling channels, this tool drastically reduces heat buildup at the cutting edge and ensures flawless chip evacuation, preventing chip nesting in deep cavities.

Product Specifications (Parameters)

Key Benefits & Functions (Product Actions)

• Superior Deep-Hole Rigidity: The 7D structure handles high aspect ratio drilling while minimizing tool deflection and vibration.

• Efficient Chip & Heat Management: Direct internal cooling flushes chips out of the hole smoothly, dramatically extending tool life and surface finish quality.

• Rapid Tool Changes: The front-locking system allows operators to swap worn drill tips quickly on the machine, reducing downtime and maximizing productivity.

• Cost-Effective Indexable System: Instead of replacing the entire drill body, you only replace the modular side-locking crown tip.

Target Applications

• Industries: Automotive manufacturing, aerospace engineering, heavy machinery, mold & die making, and energy sector production.

• Machinery: CNC Machining Centers, high-speed milling machines, and dedicated deep-hole drilling equipment.

• Common Workpieces: Drilling deep oil holes in crankshafts, cooling channels in injection molds, tube sheets in heat exchangers, and structural bolt holes.
