Product Short Description

The CSJ Crown Drill Bit (6D, Ø16.00–16.99mm) is a high-performance, indexable deep-hole drilling solution. Engineered with an advanced internal cooling system and a secure front-locking/side-locking mechanism, it delivers exceptional stability, rapid chip evacuation, and high-speed precision for challenging machining operations.

Product Introduction

Engineered for demanding industrial environments, the CSJ Crown Drill Bit redefines efficiency in high-speed, deep-hole drilling. This tool features an innovative 6D length-to-diameter ratio and a unique crown-style indexable insert design.

By combining a rigid front-locking body with a side-locking drill tip, it eliminates vibration and ensures maximum structural integrity under high torque. The integrated internal cooling holes deliver coolant directly to the cutting edge, drastically reducing thermal wear and guaranteeing superior surface finishes even at extreme depths.

Product Functions & Benefits (产品作用)

High-Speed Deep Hole Penetration: The 6D capability allows for fast, continuous drilling up to six times the diameter without the need for frequent pecking cycles.
Dual-Locking Stability: The fusion of front-locking and side-locking mechanisms provides maximum clamping rigidity, preventing insert shifting and minimizing runout.
Advanced Thermal Management: Internal through-coolant channels flush out chips instantly and lower cutting temperatures, significantly extending tool life.
Cost-Efficient Indexable Design: Instead of replacing the entire drill body, users only need to swap or index the crown tip, drastically reducing tooling costs and downtime.

Application Scenarios

The CSJ Crown Drill Bit is optimized for heavy-duty CNC machining, boring, and drilling operations across various high-precision industries:

Automotive Manufacturing: Drilling engine blocks, crankshafts, and heavy powertrain components.
Aerospace & Defense: Machining high-strength alloy landing gears, structural frames, and turbine components.
Mold & Die Industry: Creating deep water-cooling lines and core pins in complex injection molds.
Heavy Machinery & Energy: Fabricating wind turbine hubs, pressure vessels, and oil/gas piping flanges.
