Product Short Description

Engineered for high-efficiency and maximum stability, the CSJ Crown Drill Bit (5D) features a specialized front-locking body and an internal cooling system designed for high-speed, deep-hole drilling. Accommodating a 22.00–22.99 mm diameter range, this indexable insert drill delivers exceptional rigidity and chip evacuation, making it the ultimate solution for demanding machining environments.

Product Introduction

The CSJ Crown Drill Bit represents the next generation of high-speed deep-hole drilling technology. Combining the flexibility of an indexable insert system with the robust stability of a side-locking drill tip, this 5D drilling body minimizes vibration and maximizes precision.

Its advanced front-locking mechanism ensures quick, secure tip replacements without removing the entire body from the machine, dramatically reducing downtime. Equipped with dual internal cooling channels, it delivers coolant directly to the cutting edge, effectively dissipating heat and flushing out chips in deep-hole operations to ensure a flawless surface finish and extended tool life.

Key Product Functions & Benefits

High-Speed Deep Drilling: The 5D depth capability allows for rapid, precise deep-hole drilling without compromising structural integrity or accuracy.
Superior Rigidity (Front & Side-Locking): The combination of a front-locking body and side-locking tip provides tight clamping tolerance, minimizing radial runout and preventing insert shifting under heavy loads.
Advanced Thermal Control: Internal cooling channels deliver high-pressure coolant directly to the cutting zone, reducing thermal wear on the tool and preventing work-hardening of the workpiece.
Cost-Efficient Indexable Design: Eliminates the need for regrinding. Once the drill tip is worn, simply replace the crown insert to restore 100% cutting efficiency.

Application Scenarios

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

Automotive Manufacturing: High-precision drilling of engine blocks, crankshafts, and transmission components.
Aerospace & Defense: Machining tough alloys for structural components and landing gears where deep-hole precision is non-negotiable.
Mold & Die Industry: Efficient drilling of deep core cooling lines and ejector pin holes in heavy mold bases.
General Engineering & Energy: Heavy machining of wind turbine parts, pressure vessels, and large-scale flanges.
Compatible Materials: Optimized for Steel, Alloy Steel, Cast Iron, Stainless Steel, and High-Temperature Alloys.
