FANAR Solid Carbide Drill Bit 4.90mm 3xD VHM Blue Cut

The FANAR solid carbide drill bit, with a diameter of 4.90mm and a 3xD drilling depth, is a high-performance tool engineered for precision metalworking. Constructed from premium VHM solid carbide and enhanced with a specialized Blue Cut coating, this drill bit provides exceptional hardness and thermal stability. Its design ensures reliable performance, consistent hole quality, and efficient chip removal during demanding industrial drilling operations.

Advantages

The primary benefit of this solid carbide drill bit is its superior wear resistance, which significantly extends tool life even when working with challenging materials. The Blue Cut coating reduces friction and heat buildup, allowing for higher cutting speeds and improved surface finish. Furthermore, the robust carbide construction minimizes deflection, ensuring high dimensional accuracy and repeatability in every hole produced.

Suitable for

• Precision drilling in steel and cast iron
• High-volume production environments
• CNC machining centers
• General metal fabrication tasks

This drill bit may not be suitable for use on hand-held power drills, as the rigidity of solid carbide requires a stable, vibration-free machine setup to prevent breakage. It is also not intended for drilling soft, non-metallic materials like wood or plastic, where specialized geometries would be more effective.

Key specifications

• Diameter: 4.90mm
• Drilling depth: 3xD
• Material: Solid carbide (VHM)
• Coating: Blue Cut
• Shank type: HA

To use this drill bit, ensure it is securely mounted in a high-precision collet or hydraulic chuck within a rigid machine tool. Align the workpiece accurately and apply appropriate cutting parameters, including speed and feed rates, tailored to the specific material being machined. Always use a suitable coolant to maximize the benefits of the Blue Cut coating and ensure optimal chip evacuation.

What to consider before purchase

• Verify that your machine tool provides the necessary rigidity for carbide tooling
• Ensure the 3xD length is sufficient for your specific application depth
• Check that your collet system is compatible with the HA shank design

For best results, maintain consistent coolant flow throughout the drilling process and monitor the tool for signs of wear to prevent potential breakage during high-speed operations.
