FANAR Solid Carbide Drill Bit 3.10mm 3xD VHM BLUE CUT

The FANAR solid carbide drill bit, with a diameter of 3.10mm and a 3xD drilling depth, is a high-performance tool engineered for precision metalworking. Constructed from premium solid carbide (VHM) and enhanced with a specialized BLUE CUT coating, this drill bit is designed to withstand demanding industrial environments while maintaining dimensional accuracy. Its geometry is optimized for efficient chip evacuation, reducing heat buildup and extending the operational life of the tool during repetitive drilling tasks.

Advantages

The primary benefit of this solid carbide drill bit lies in its exceptional wear resistance provided by the BLUE CUT coating, which allows for higher cutting speeds and improved surface finish quality. The rigid carbide construction minimizes deflection, ensuring that holes are drilled with high positional accuracy. Furthermore, the design facilitates smooth chip removal, which prevents clogging and reduces the risk of tool breakage, making it a reliable choice for high-volume production environments.

Suitable for

• Precision drilling in steel and cast iron
• Industrial machining and CNC applications
• High-accuracy hole production in metal components
• Repetitive drilling tasks requiring consistent tool performance

When it may not be suitable

This drill bit is not recommended for drilling in soft, non-metallic materials such as wood or plastics, as the geometry is specifically optimized for metal cutting. Additionally, it may not be suitable for use in handheld power drills due to the high rigidity of the carbide material, which can be prone to snapping if not supported by a stable, vibration-free machine setup.

Key specifications

• Diameter: 3.10mm
• Material: Solid Carbide (VHM)
• Coating: BLUE CUT
• Drilling depth: 3xD

How to use

Ensure the drill bit is securely mounted in a high-precision collet or hydraulic chuck to minimize runout. Before starting the operation, verify that the workpiece is firmly clamped to prevent vibration. Use appropriate cooling lubricant to maximize the benefits of the BLUE CUT coating and to assist in chip evacuation. Begin the drilling process at the manufacturer-recommended feed and speed rates for the specific material being machined to ensure optimal performance and tool longevity.

What to consider before purchase

• Verify that your machine setup is rigid enough for solid carbide tooling
• Ensure the 3xD drilling depth is sufficient for your specific application
• Check compatibility with your existing tool holders
• Confirm the material hardness of your workpiece matches the drill bit's intended use

Usage recommendations

For best results, always maintain consistent coolant flow to the cutting zone and avoid sudden impacts or lateral pressure during the drilling process to prevent carbide chipping.
