CSJ Crown Drill Bit (6D, Ø37.00–37.99 mm)

High-Performance Indexable Deep-Hole Drilling System

1. Short Description

The CSJ Crown Drill Bit is a high-speed, high-efficiency 6D deep-hole indexable drilling tool designed for diameter ranges from 37.00 mm to 37.99 mm. Featuring a rigid front-locking body architecture and integrated internal cooling channels, it delivers exceptional stability, rapid chip evacuation, and prolonged tool life during heavy-duty industrial drilling operations.

2. Product Features

High-Aspect Ratio Drilling (6D): Engineered specifically for deep-hole applications, achieving drilling depths up to 6 times the drill diameter without sacrificing structural rigidity or hole accuracy.
Secure Front-Locking Mechanism: The advanced front-locking design ensures quick, precise insert replacements and highly reliable clamping, minimizing vibration under heavy cutting loads.
Advanced Internal Cooling: Dual through-tool coolant channels deliver high-pressure fluid directly to the cutting edge, drastically reducing thermal stress and ensuring seamless chip evacuation from deep cavities.
Indexable / Side-Locking Design: Features an optimized indexable insert configuration and side-locking drill tip alignment that eliminates the need for tool regrinding, drastically lowering operational downtime.

4. Product Functions & Benefits

Maximizes Material Removal Rates (MRR): Engineered for high-speed machining, cutting down cycle times compared to traditional twist drills.
Extends Tool Life: The synchronized internal cooling system rapidly dissipates heat from the cutting zone, preventing thermal degradation of the indexable inserts.
Improves Surface Finish & Straightness: Enhanced body rigidity combined with precise side-locking tips guarantees excellent hole linearity, tight dimensional tolerances, and a clean surface finish.
Reduces Tooling Costs: When the cutting edge wears out, only the indexable insert or tip needs replacement—saving raw material and tooling overhead.

5. Target Applications

This industrial-grade drill bit is ideal for demanding sectors requiring deep, large-diameter holes in tough materials (such as carbon steel, alloy steel, stainless steel, and cast iron):

Heavy Machinery Manufacturing: Production of large structural components, hydraulic cylinders, and heavy-duty frame fixtures.
Automotive & Locomotive Industries: Drilling large-diameter shafts, axles, and powertrain blocks.
Energy & Power Generation: Machining tube sheets for heat exchangers, pressure vessels, and wind turbine components.
Mold & Die Industry: Deep-hole drilling for core cooling lines in massive injection molds.
Aerospace & Defense: High-precision deep drilling of structural components and landing gear assemblies.
