Solid Carbide Drill Bit 5.00 mm 5xD with Internal Cooling TiB2 Coated

The Solid Carbide Drill Bit 5.00 mm 5xD with Internal Cooling and TiB2 coating is a high-performance cutting tool engineered for precision and durability in industrial metalworking environments. With a 5.00 mm diameter and a 5xD drilling depth, this drill bit is designed to maintain structural integrity and accuracy during deep hole drilling operations. The integration of internal cooling channels ensures that coolant is delivered directly to the cutting zone, which significantly improves chip evacuation and prevents overheating during prolonged use.

Advantages

This drill bit offers exceptional performance due to its solid carbide construction, which provides superior rigidity and resistance to deformation compared to standard steel bits. The specialized TiB2 (Titanium Diboride) coating serves as a protective barrier that minimizes friction and enhances wear resistance, allowing for higher cutting speeds and extended tool life. By facilitating efficient heat dissipation through internal channels, the tool reduces the risk of thermal damage to both the workpiece and the cutting edge, ensuring consistent hole quality and dimensional stability.

Suitable for

• High-precision drilling in steel, aluminum, and non-ferrous alloys
• Deep hole drilling applications requiring a 5xD depth ratio
• Automated CNC machining centers with through-spindle coolant systems
• Mass production environments where tool longevity and cycle time are critical

When it may not be suitable

This drill bit is not recommended for use on manual drilling machines that lack high-pressure internal cooling systems, as the internal channels will not function correctly without a compatible coolant supply. Additionally, it is not intended for drilling hardened materials that exceed the hardness specifications of the carbide grade.

Key specifications

• Diameter: 5.00 mm
• Drilling depth: 5xD
• Material: Solid carbide
• Coating: TiB2 (Titanium Diboride)
• Cooling: Internal cooling channels

How to use

To achieve optimal results, 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 internal cooling system is properly connected and that the coolant pressure is sufficient to clear chips from the hole. Begin the drilling process with appropriate feed and speed settings tailored to the material being machined. It is recommended to use a pilot hole if the surface is uneven or angled to prevent drill walking and ensure the accuracy of the 5.00 mm diameter hole.

What to consider before purchase

• Verify that your machine tool supports internal coolant delivery
• Ensure the collet or chuck is compatible with the shank diameter
• Check the material compatibility for TiB2 coated tools
• Confirm the required drilling depth does not exceed the 5xD capacity

Usage recommendations

For maximum tool life and performance, always maintain consistent coolant flow and monitor the condition of the cutting edge regularly. Avoid excessive feed rates that could lead to chip clogging, especially when drilling to the full 5xD depth.
