Product Short Description

The CSJ Crown Drill Bit is a high-performance 7D indexable insert drill engineered for deep-hole machining within a 35.00–35.99 mm diameter range. Featuring an advanced front-locking insert body and integrated internal cooling, it delivers exceptional stability, high-speed chip evacuation, and extended tool life during demanding metal-cutting operations.

Product Overview

Designed for maximum efficiency and precision, the CSJ Crown Drill Bit features a secure front-locking and side-locking mechanism that enables fast, hassle-free tip replacements without removing the drill holder from the machine. Its 7D depth capability (up to 7x diameter) allows for deep-hole drilling with minimal deflection. Equipped with an internal cooling system, it directly delivers high-pressure coolant to the cutting zone—effectively dissipating heat, reducing friction, and ensuring smooth chip removal during high-speed applications.

Key Functions & Capabilities

Efficient Deep-Hole Drilling: Enables high-speed drilling up to 7D depth while maintaining dimensional accuracy and hole straightness.
Rapid Tool Changes: Front- and side-locking mechanisms allow quick insert replacement on-machine, minimizing tool setup times and operational downtime.
Thermal & Chip Management: Internal coolant channels blast high-pressure fluid directly onto the cutting edge to reduce thermal stress and rapidly force chips out of deep cavities.
Cost Efficiency: Indexable crown tip design lets you replace only the worn cutting insert rather than the whole drill body, significantly lowering tooling overhead.

Application Scenarios

Heavy Machinery & Equipment: Drilling large-diameter structural holes in frames, flanges, and structural plates.
Automotive & Commercial Vehicles: Machining engine blocks, driveshafts, and heavy axle components.
Energy & Power Generation: Deep-hole boring for wind turbine components, oil & gas valve bodies, and heat exchangers.
Aerospace & Mold Manufacturing: Processing high-strength alloy steels, stainless steel, and cast iron parts requiring precise deep-hole geometry.
