CSJ Crown Drill Bit, 6D Drill Diameter Range 24.00-24.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Overview

Short Description

The CSJ Crown Drill Bit is a high-performance 6D indexable insert drill engineered for high-speed, deep-hole machining. Featuring a front-locking body, a side-locking drill tip, and an advanced internal cooling system, it delivers exceptional stability, chip evacuation, and precision for hole diameters ranging from 24.00mm to 24.99mm.

Product Introduction

The CSJ Crown Drill Bit series represents the next generation of deep-hole drilling technology. Designed to handle demanding industrial tasks, its 6D depth capability allows you to drill holes up to six times the drill’s diameter without compromising on accuracy.

Equipped with a secure front-locking body and a stable side-locking drill tip, this tool minimizes vibration and ensures perfect alignment even under heavy axial loads. The integration of high-pressure internal cooling channels delivers coolant directly to the cutting edge, drastically reducing thermal stress, preventing chip clogging, and substantially extending the lifespan of the indexable insert.

Product Specifications (Parameters)

Key Functions & Product Benefits (Product Role)

• High-Speed Deep Hole Drilling: Achieves a 6D depth ratio efficiently, eliminating the need for frequent pecking cycles.

• Superior Chip Evacuation: The internal cooling system flushes chips out of the deep hole smoothly, preventing workpiece damage and tool breakage.

• Enhanced Rigidity and Accuracy: The dual front-locking and side-locking mechanisms provide a rock-solid connection, ensuring high centering accuracy and minimal runout.

• Cost-Efficient Operation: The indexable crown insert design allows you to replace only the worn tip rather than the entire drill body, significantly lowering tooling costs.

Application Scenarios

The CSJ Crown Drill Bit is optimized for heavy-duty manufacturing sectors requiring high-precision deep holes, including:

• Automotive Industry: Drilling engine blocks, crankshafts, and heavy-duty transmission components.

• Aerospace & Defense: Machining high-strength alloy landing gears and structural frames.

• Mold & Die Making: Creating deep ejector pin holes and complex water cooling lines in large mold bases.

• Heavy Machinery & Energy: Processing tube sheets for heat exchangers, wind turbine components, and oil/gas drilling equipment.

• Compatible Materials: Excellent performance in Carbon Steel, Alloy Steel, Stainless Steel, Cast Iron, and High-Temperature Alloys.
