CSJ Crown Drill Bit, 6D Drill Diameter Range 31.00-31.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Short Description

High-performance CSJ Crown Drill Bit (6D) featuring a 31.00–31.99 mm diameter range, a secure front-locking body, and internal cooling channels. Designed as an indexable insert/side-locking drill tip system, it delivers maximum stability and chip evacuation for high-speed, deep-hole drilling applications.

Product Overview

The CSJ Crown Drill Bit represents the next generation of indexable deep-hole drilling technology. Engineered for demanding industrial environments, this 6D length-to-diameter ratio drill body utilizes a robust front-locking and side-locking mechanism to secure the replaceable crown insert.

Equipped with advanced internal cooling channels, it delivers high-pressure coolant directly to the cutting edges. This drastically reduces thermal stress and ensures seamless chip evacuation, preventing chip packing during deep-hole penetration. The modular crown system allows you to replace worn tips quickly without removing the entire tool body, significantly minimizing downtime and boosting productivity.

Technical Specifications

Key Benefits & Functions (Product Features)

• Rapid Chip Evacuation: Internal cooling channels force coolant directly into the hole, lifting chips out quickly to prevent clogging and tool breakage in 6D deep holes.

• High-Speed Stability: The dual front-locking body and side-locking tip provide maximum rigidity, eliminating vibration and ensuring high surface finish quality.

• Cost-Effective Modular Design: No need to replace the entire drill body; simply swap out the indexable crown insert when worn out, cutting tooling costs.

• Exceptional Hole Accuracy: The precision-ground crown geometry guarantees tight hole tolerances and excellent straightness over long drilling depths.

Target Applications (Use Cases)

• Heavy Machinery & Automotive Manufacturing: Drilling deep structural holes in engine blocks, crankshafts, and heavy frames.

• Oil & Gas Industry: Machining high-strength alloys for valves, manifolds, and deep-well drilling components.

• Aerospace & Defense: High-speed hole making in tough materials like titanium, stainless steel, and specialized alloy steels.

• Mold & Die Production: Efficiently drilling deep water-cooling lines and ejector pin holes in large mold bases.
