CSJ Crown Drill Bit, 6D Drill Diameter Range 26.00-26.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Product Short Description

High-performance CSJ Crown Drill Bit (6D) featuring a 26.00–26.99mm diameter range, a secure front-locking body, and internal cooling. Engineered for high-speed, precision deep-hole drilling with indexable, side-locking drill tips.

Product Introduction

The CSJ Crown Drill Bit (6D) is a premium-grade engineering solution designed for demanding high-speed deep-hole drilling applications. Featuring an advanced front-locking body mechanism paired with a secure side-locking drill tip, this indexable insert drill ensures maximum stability, minimal vibration, and exceptional rigidity even under heavy cutting loads.

Equipped with a cutting-edge internal cooling system, it delivers coolant directly to the cutting edge, drastically reducing thermal stress, optimizing chip evacuation, and extending tool life. With a 6D depth capability, it provides the perfect balance of speed, accuracy, and cost efficiency for modern CNC machining.

Product Parameters

Key Product Benefits (Product Action)

• Superior Chip Evacuation: The specialized internal cooling channels flush chips out effortlessly from deep holes, preventing chip packing and tool breakage.

• High Rigidity & Precision: The dual-action locking system (front-locking body + side-locking tip) eliminates micro-movements, ensuring high hole concentricity and excellent surface finish.

• Cost-Efficient Indexable Design: No need to replace the entire drill body. Simply index or replace the crown insert when worn, drastically reducing tooling costs and downtime.

• High-Speed Efficiency: Optimized geometry allows for higher feed rates and cutting speeds compared to traditional twist drills.

Application Scenarios

This industrial-grade drill bit is ideal for heavy-duty metalworking industries requiring deep-hole drilling up to 6D depth:

• Heavy Machinery & Automotive: Drilling engine blocks, crankshafts, and heavy transmission components.

• Oil & Gas Industry: Machining high-strength valves, flanges, and piping manifolds.

• Mold & Die Manufacturing: Creating deep water cooling channels in large injection molds.

• Aerospace & Energy: Processing tough alloys and structural components for turbines and generators.

• Compatible Materials: Structural steel, alloy steel, stainless steel, cast iron, and high-temperature alloys.
