CSJ Crown Drill Bit, 6D Drill Diameter Range 36.00-36.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

CSJ Crown Drill Bit (6D, Ø36.00mm – 36.99mm)

High-Speed Deep-Hole Indexable Drill with Internal Cooling

Product Overview

The CSJ Crown Drill Bit is a high-performance, indexable insert drilling solution engineered specifically for high-speed, deep-hole applications. Featuring a robust 6D drilling depth capability and a high-precision front-locking body mechanism, this tool delivers maximum stability and rigidity when drilling diameters ranging from 36.00mm to 36.99mm. Combined with advanced internal cooling channels, it ensures optimal chip evacuation and prolonged tool life under heavy-duty machining conditions.

Key Features & Benefits (Product Introduction)

• Front-Locking Secure Design: The specialized front-locking body with a side-locking drill tip configuration ensures rapid insert replacement directly inside the machine, maintaining precise repeatability and minimizing operational downtime.

• 6D Deep-Hole Capability: Specially engineered to drill depths up to 6 times the drill diameter without sacrificing accuracy, straightness, or surface finish quality.

• Advanced Internal Cooling: Dual through-coolant holes deliver high-pressure fluid directly to the cutting edge, rapidly lowering temperatures and forcing chips out of deep cavities to prevent chip packing.

• Indexable Versatility: Utilizes high-efficiency indexable crown inserts, eliminating the need for regrinding and ensuring consistent cutting performance throughout its lifespan.

Product Specifications (Product Parameters)

Functionality & Mechanism (Product Action)

The CSJ Crown Drill functions as a heavy-duty material removal tool. It utilizes a rigid indexable tip that balances cutting forces perfectly along the drill center line, preventing deflection in deep bores. The integrated internal cooling system serves a dual purpose: it instantly mitigates the thermal shock experienced by the cutting edges during high-speed friction and generates enough hydraulic pressure to flush chips backwards along the wide flutes of the 6D body.

Target Applications (Application Scenes)

This drilling system is optimized for heavy industrial manufacturing sectors that require high-efficiency, large-diameter deep hole making:

• Heavy Machinery & Energy: Drilling deep blind or through-holes in wind turbine hubs, large gearboxes, and generator rotor shafts.

• Oil & Gas Industry: Machining high-strength tube sheets, valve bodies, and oil field exploration equipment parts.

• Automotive & Maritime: High-volume boring of marine diesel engine blocks, crankshafts, and heavy-duty truck axle components.

• Mold & Die Manufacturing: Ejector pin hole drilling and deep coolant channel fabrication in massive injection mold bases.
