EL-CUT Solid Carbide Drill Bit 3.30 mm, 5xD, HA6 Shank

The EL-CUT solid carbide drill bit with a 3.30 mm diameter is a high-performance cutting tool designed for precision metalworking. Engineered with a 5xD drilling depth ratio, this drill bit provides excellent stability and accuracy when creating deep holes in various metallic materials. Its solid carbide construction ensures superior hardness and wear resistance, allowing for consistent performance during demanding industrial operations. The inclusion of an HA6 shank facilitates a secure and reliable fit in standard tool holders, minimizing vibration and enhancing overall machining quality.

Advantages

This solid carbide drill bit offers exceptional durability and heat resistance, which are critical for maintaining tight tolerances in professional machining environments. The geometry of the tool is optimized for efficient chip evacuation, preventing clogging and reducing the risk of tool breakage during deep hole drilling. By utilizing high-quality carbide material, the drill bit maintains its sharpness over extended periods, leading to increased productivity and reduced downtime for tool changes. The precise design ensures clean hole finishes, reducing the need for secondary finishing operations.

Suitable for

• High-precision drilling in steel and cast iron
• Industrial metalworking and machining centers
• Applications requiring a 5xD depth-to-diameter ratio
• Operations where high dimensional accuracy is essential

When it may not be suitable

This drill bit is not intended for use with hand-held power drills, as the rigidity of the carbide material requires a stable, vibration-free machine setup to prevent snapping. It is also not recommended for drilling soft, non-metallic materials like wood or plastic, where specialized geometries are required to prevent melting or tearing.

Key specifications

• Diameter: 3.30 mm
• Drilling depth ratio: 5xD
• Material: Solid carbide (VHM)
• Shank type: HA6

How to use

To achieve optimal results, ensure the drill bit is mounted securely in a high-precision collet or hydraulic tool holder. Before starting the drilling process, verify that the workpiece is firmly clamped to prevent movement. Use appropriate cutting speeds and feed rates based on the material being machined, and ensure a consistent supply of coolant to facilitate chip removal and maintain temperature control. Always start with a center drill or pilot hole if the surface is uneven to ensure the drill bit enters the material accurately.

What to consider before purchase

• Verify that your machine tool is compatible with the HA6 shank specification.
• Ensure the 5xD depth ratio meets the specific requirements of your project.
• Confirm that the material you are drilling is suitable for solid carbide tooling.

Usage recommendations

Always inspect the drill bit for signs of wear or chipping before each use to maintain safety and precision. Replace the tool immediately if performance decreases to avoid damaging the workpiece.
