CSJ Crown Drill Bit, 5D Drill Diameter Range 25.00⁓25.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

The CSJ Crown Drill Bit (5D, $\varnothing$ 25.00–25.99 mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an advanced front-locking body and an integrated internal cooling system, it delivers exceptional chip evacuation, stability, and precision in demanding industrial machining applications.

Product Introduction

Take your deep-hole drilling efficiency to the next level with the CSJ Crown Drill Bit. Designed for rugged industrial environments, this 5D indexable drill body accommodates a diameter range of 25.00 mm to 25.99 mm.

At its core is a robust front-locking mechanism paired with a side-locking drill tip, ensuring maximum structural rigidity and rapid insert replacement with minimal downtime. To combat the extreme heat generated during high-speed deep drilling, the body features engineered internal cooling channels that deliver coolant directly to the cutting edge. This drastically reduces thermal wear, extends tool life, and ensures ultra-smooth chip evacuation.

Product Parameters

Product Functions & Benefits

• High-Speed Deep Drilling: The 5D depth capacity combined with a rigid body allows for aggressive feed rates and high cutting speeds without sacrificing hole accuracy.

• Advanced Internal Cooling: Dual internal coolant holes flush chips out of the deep cavity instantly while keeping the cutting edge cool, preventing tool breakage.

• Secure Dual-Locking Design: The combination of a front-locking body and side-locking tip guarantees zero insert movement under heavy torque and axial forces.

• Cost-Efficient Indexable System: No need to replace the entire drill body—simply swap or index the drill tip/inserts, drastically lowering your cost-per-hole.

Application Applications

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty CNC machining, boring machines, and radial drills. It is widely used in the following industries:

• Mold & Die Manufacturing: Drilling deep core fluid/cooling channels in large mold bases.

• Automotive & Aerospace: Machining engine blocks, shafts, and structural components requiring precise deep holes.

• Heavy Machinery: Production of hydraulic cylinders, power generation components, and large flanges.

• Oil & Gas: Drilling high-strength alloy valves, pipes, and manifolds.
