CSJ Crown Drill Bit,10D Drill Diameter Range 35.00-35.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

1. Short Description (Brief Summary)

The CSJ Crown Drill Bit (10D Series) is engineered for high-precision, deep-hole drilling with a drilling depth capability of up to 10 times the diameter (10D). Designed to cover a drill diameter range of 35.00mm – 35.99mm, it features a robust front-locking system paired with an internal cooling channel for superior chip evacuation and thermal management. Suitable for indexable inserts and side-locking drill tips, this tool delivers high feed rates, exceptional hole accuracy, and extended tool life in demanding industrial metalworking operations.

2. Product Introduction

The CSJ 10D Crown Drill Bit System represents an advanced solution for heavy-duty, deep-hole metal cutting. Engineered for high-speed machining environments, this tool integrates a specialized front-locking body mechanism with an interchangeable crown / side-locking insert system.

By combining high-rigidity tool steel construction with targeted internal coolant passages, the CSJ Crown Drill minimizes thermal expansion, friction, and chip congestion during deep penetration (up to 10D). It offers exceptional stability, minimal deflection, and consistent dimensional accuracy, making it ideal for high-productivity B2B manufacturing in machinery, automotive, aerospace, and heavy equipment industries.

4. Key Product Functions & Features (Product Role)

• Deep-Hole Drilling Efficiency (10D Depth): Achieves deep-hole drilling capabilities up to 10 times the tool diameter in a single pass without frequent pecking cycles.

• Front-Locking Quick Change System: Features a front-locking design that enables fast, secure, and accurate head replacements directly on the machine, drastically cutting down downtime and tooling reset costs.

• Efficient Internal Cooling & Chip Evacuation: Directs high-pressure coolant directly to the cutting edge, rapidly lowering temperatures and flushing out chips to prevent tool jamming and work hardening.

• High-Rigidity Structure: Eliminates vibration and tool deflection during deep penetration, ensuring smooth surface finish and precise hole tolerance.

• Cost-Effective Indexable Design: Allows replacing only the worn crown/side-locking tip while retaining the heavy-duty drill body, reducing long-term tool consumable expenditure.
