FANAR X-DRILL Solid Carbide Drill Bit 4.00mm, 5xD, DIN 6537

The FANAR X-DRILL 4.00mm solid carbide drill bit is a high-precision cutting tool engineered for demanding industrial metalworking environments. Manufactured from premium VHM solid carbide, this drill bit offers exceptional hardness and thermal resistance, ensuring consistent performance during intensive drilling operations. Designed to meet DIN 6537 standards, it provides a 5xD drilling depth, making it an ideal choice for deep-hole drilling where accuracy and hole quality are paramount.

Advantages

The primary advantage of the FANAR X-DRILL lies in its advanced geometry, which facilitates superior chip evacuation and reduces cutting forces. This design minimizes heat buildup, thereby extending the tool life and maintaining high dimensional accuracy throughout the machining process. Its solid carbide construction provides the rigidity necessary to prevent deflection, ensuring that every hole is drilled with precision even in challenging materials.

Suitable for

• Precision drilling in steel and cast iron
• Deep-hole drilling applications up to 5xD
• Automated CNC machining centers
• Professional metalworking and tool manufacturing

When it may not be suitable

This drill bit is not intended for use with hand-held power drills due to its rigid carbide construction, which is prone to breakage under manual vibration or misalignment. It is also not recommended for drilling very soft or abrasive materials that may require specific coating geometries not present in this standard industrial design.

Key specifications

• Diameter: 4.00mm
• Drilling depth: 5xD
• Material: VHM solid carbide
• Standard: DIN 6537
• Shank type: HA cylindrical

How to use

To achieve optimal results, the drill bit should be mounted in a high-precision collet chuck or hydraulic holder to ensure minimal runout. It is essential to use a stable, rigid machine setup and provide a consistent supply of coolant to the cutting zone to assist with chip removal and temperature control. Always ensure the workpiece is securely clamped before starting the drilling cycle.

What to consider before purchase

• Verify the compatibility of the 4.00mm diameter with your specific hole requirements
• Ensure your machine spindle has the necessary runout precision for carbide tooling
• Confirm that your coolant system is capable of high-pressure delivery for deep-hole drilling

Usage recommendations

For maximum tool longevity, maintain recommended cutting speeds and feed rates specific to the material being machined. Regularly inspect the cutting edges for signs of wear to prevent hole inaccuracy or tool failure.
