CSJ Crown Drill Bit, 4D Drill Diameter Range 37.00-37.99, Front-Locking Body with Internal Cooling for High-Speed Deep-Hole Drilling, Indexable Insert Drill / Side-Locking Drill Tip

Here is a professional, high-converting product listing tailored for your CSJ Crown Drill Bit. It is structured into clear sections designed to attract B2B buyers and machinists.

Product Short Description

The CSJ Crown Drill Bit (4D) is a high-performance, indexable deep-hole drilling solution engineered for precision and speed. Featuring an advanced front-locking design and a 4D drilling depth capacity, this tool ensures maximum stability and excellent chip evacuation via internal cooling channels. Designed for heavy-duty industrial applications, it delivers superior surface finishes and extended tool life in high-speed operations.

Product Overview

The CSJ Crown Drill Bit redefines efficiency in deep-hole machining. Built with a robust front-locking body and a secure side-locking drill tip, this indexable insert drill minimizes vibration and runout even under high feed rates.

Its defining feature is the integrated internal cooling system, which delivers high-pressure coolant directly to the cutting edge. This rapidly lowers temperatures, prevents thermal deformation, and flushes out chips effortlessly, making it the ultimate choice for continuous, high-speed production lines.

Product Parameters

Key Functions & Product Benefits

• High-Speed Deep-Hole Penetration: The 4D depth capability allows for rapid, single-pass deep drilling without the need for frequent peck-drilling cycles.

• Superior Rigid Clamping: The dual-action front-locking and side-locking mechanism guarantees that the drill tip remains perfectly centered under heavy axial loads.

• Advanced Thermal Control: Internal cooling channels maximize coolant flow directly to the friction zone, drastically extending insert lifespan and preventing work-hardening of the workpiece.

• Cost-Efficient Indexable Design: No need to replace the entire drill body. Simply index or replace the crown carbide tip, reducing tooling costs and minimizing machine downtime.

Application Scenarios

This industrial-grade drill bit is highly versatile and optimized for heavy manufacturing sectors:

• Automotive Industry: Precision drilling of engine blocks, crankshafts, and heavy-duty drivetrain components.

• Aerospace & Defense: Machining high-strength alloys and structural components requiring strict dimensional accuracy.

• Oil & Gas / Energy: Ideal for tube sheets, heat exchangers, flanges, and high-pressure valve bodies.

• Heavy Machinery: Production of large hydraulic cylinders, molds, dies, and structural steel frames.

• Material Versatility: Highly effective in drilling carbon steel, alloy steel, stainless steel, cast iron, and high-temperature superalloys.
