CSJ Crown Drill Bit, 4D Drill Diameter Range 16.00-16.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

The CSJ Crown Drill Bit (4D) is a premium indexable insert drill engineered for high-speed, deep-hole drilling. Featuring a front-locking body, internal cooling channels, and a secure side-locking drill tip, this 16.00–16.99mm diameter drill delivers exceptional chip evacuation, high precision, and extended tool life in demanding manufacturing environments.

Product Introduction

The CSJ Crown Drill Bit is a state-of-the-art hole-making solution designed to bridge the gap between solid carbide drills and standard indexable drills. Engineered with a 4D depth capability, it utilizes a rigid front-locking system paired with a side-locking tip to ensure maximum stability and minimize runout during high-speed operations.

Equipped with advanced internal cooling channels, the coolant is directed precisely to the cutting edge. This drastically reduces thermal stress, prevents chip packing, and allows for uninterrupted, high-efficiency deep-hole drilling without the need for frequent pecking cycles.

Technical Parameters

Key Functions & Product Benefits

• High-Speed Deep-Hole Penetration: The 4D length-to-diameter ratio allows for deep boring while maintaining high feed rates and structural rigidity.

• Advanced Thermal Control: Dual internal coolant holes flush chips out effortlessly and keep the cutting zone cool, preventing work hardening of the material.

• Superior Accuracy & Stability: The hybrid front- and side-locking mechanism locks the insert crown securely, ensuring high repeatability, excellent surface finish, and minimal vibration.

• Cost-Efficient Insert System: No need to replace or regrind the entire drill body. Simply swap out the crown insert tip when worn, significantly reducing tooling costs and downtime.

Application Scenarios

The CSJ Crown Drill Bit is highly versatile and optimized for heavy-duty CNC machining, including:

• Industries: Automotive manufacturing, aerospace engineering, oil & gas component machining, mold and die making, and heavy machinery production.

• Equipment: Suitable for CNC Machining Centers, Lathes with live tooling, Boring Mills, and Radial Drilling Machines with through-coolant capabilities.

• Workpiece Materials: Exceptional performance in carbon steels, alloy steels, stainless steels, cast iron, and high-temperature alloys.
