CSJ Crown Drill Bit, 5D 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

Product Short Description

The CSJ Crown Drill Bit (5D, Ø31.00–31.99mm) is a high-performance indexable insert drill engineered for high-speed, deep-hole drilling. Featuring an advanced front-locking body design and an integrated internal cooling system, this heavy-duty side-locking drill tip delivers exceptional stability, superior chip evacuation, and maximum productivity in demanding machining environments.

Product Introduction

Designed for precision and endurance, the CSJ Crown Drill Bit bridges the gap between solid carbide drills and traditional indexable drills. It utilizes a robust front-locking body mechanism paired with a secure side-locking drill tip, ensuring rigid clamping and minimal runout even under high cutting forces. With a 5D drilling depth capacity (5 times the drill diameter), it is specifically optimized for deep-hole penetration. The built-in internal cooling channels deliver high-pressure coolant directly to the cutting edge, drastically reducing thermal stress, preventing chip clogging, and significantly extending tool life.

Product Parameters

Product Functions & Benefits

• High-Speed Deep-Hole Penetration: Effortlessly achieves high material removal rates (MRR) at 5D depths without sacrificing hole straightness.

• Superior Thermal Management: Dual internal cooling holes flush out heat instantly, protecting both the workpiece and the crown insert.

• Exceptional Rigid Clamping: The dual-action front-locking and side-locking system eliminates vibrations, resulting in excellent surface finishes and strict dimensional accuracy.

• Cost-Efficient Maintenance: The indexable/replaceable crown tip design means you only replace the worn head, not the entire drill body, reducing tooling costs.

• Optimized Chip Evacuation: Engineered flute geometry seamlessly clears out chips, preventing catastrophic tool breakage during deep pocketing.

Application Scenarios

This industrial-grade drill bit is ideal for heavy machining across various sectors, including:

• Aerospace & Defense: Drilling structural components and engine mounts requiring tight tolerances.

• Automotive Manufacturing: High-volume drilling of engine blocks, crankshafts, and heavy-duty chassis parts.

• Mold & Die Industry: Deep-hole drilling for cooling lines in large injection molds.

• Oil, Gas & Energy: Machining heavy pipe sheets, flanges, and valves for high-pressure systems.

• General Engineering: Heavy-duty fabrication involving tough materials like carbon steel, alloy steel, stainless steel, and cast iron.
