CSJ Crown Drill Bit,10D Drill Diameter Range 9.50-9.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

The CSJ Series Front-Locking Crown Drill Bit (10D) is engineered for high-precision, deep-hole drilling across a 9.50–9.99 mm diameter range. Featuring indexable insert technology, an advanced front-locking system, and integrated internal cooling, it delivers exceptional stability, high-speed chip evacuation, and extended tool life in demanding industrial machining.

Product Introduction

Designed for heavy-duty manufacturing, the CSJ Crown Drill Bit simplifies deep-hole operations up to 10 times its diameter (10D). Its front-locking mechanism allows fast and secure tip replacement directly on the machine, reducing downtime and maintaining rigorous concentricity. The internal cooling channels direct high-pressure coolant directly to the cutting edge, effectively dissipating heat and sweeping chips away during continuous high-speed feeds.

Product Parameters

Key Functions & Capabilities

• Deep-Hole Precision: Enables stable 10D deep-hole drilling with minimal runout and consistent hole accuracy.

• Efficient Heat & Chip Removal: Internal cooling reduces thermal stress on cutting edges while blasting chips clear of deep flutes.

• Rapid Tool Changes: The front-locking mechanism allows quick insert swaps without removing the tool body from the holder.

• Cost Efficiency: Utilizes indexable insert tips, eliminating the need for regrinding and reducing operational tool costs.

Application Scenarios

• Automotive Manufacturing: Engine block oil passages, crankshaft lubrication holes, and transmission components.

• Aerospace & Defense: Structural landing gear components and hydraulic fluid channels requiring strict tolerances.

• Mold & Die Making: High-depth cooling channels in injection molds and die blocks.

• Energy & Heavy Machinery: Deep-hole drilling in valve bodies, flange connections, and pressure vessels.
