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.
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.

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.
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.
