CSJ Crown Drill Bit, 7D Drill Diameter Range 10.50-10.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

CSJ Crown Drill Bit (7D, Ø10.50–10.99 mm)

High-Speed Indexable Deep-Hole Drilling System

Product Short Description

The CSJ Crown Drill Bit is a high-performance, 7D deep-hole indexable drilling system engineered for maximum speed, precision, and tool longevity. Featuring a secure front-locking body and advanced internal cooling channels, this side-locking crown drill tip delivers exceptional chip evacuation and flawless hole quality in demanding industrial metalworking applications.

Product Introduction

The CSJ Crown Drill Bit series represents the next generation of indexable deep-hole drilling technology. Built for high-efficiency machining, the 7D length-to-diameter ratio allows for deep penetration without sacrificing rigidity.

Its innovative front-locking mechanism ensures quick, seamless tool tip replacements directly on the machine, drastically reducing downtime. Coupled with a precision-engineered side-locking crown drill tip, this system provides absolute stability against heavy torsional forces, ensuring high repeatability and excellent surface finishes even at elevated cutting speeds.

Product Features & Actions (Product Functions)

• 7D Deep-Hole Capability: Effortlessly drills high-precision holes up to seven times the drill’s diameter with minimal deflection.

• Advanced Internal Cooling: Through-tool coolant channels deliver high-pressure fluid directly to the cutting edge, rapidly lowering temperatures and flushing out chips to prevent premature tool wear.

• Front-Locking Quick-Change System: Allows operators to replace the crown drill tip effortlessly without removing the entire tool holder from the spindle.

• Side-Locking Crown Tip: Provides heavy-duty clamping rigidity, eliminating micro-vibrations and ensuring tight dimensional tolerances.

• High-Speed Efficiency: Optimized chip-breaker and coating geometries support aggressive feed rates and high RPMs, maximizing your workshop’s throughput.
