Carbide Drill Bit 6.80 mm, 5xD, HA8 Shank

The Carbide Drill Bit 6.80 mm is a high-performance cutting tool engineered for precision metalworking and industrial drilling applications. With a diameter of 6.80 mm and a 5xD drilling depth, this drill bit is designed to provide consistent hole accuracy and reliable performance in demanding environments. The inclusion of an HA8 shank ensures a secure fit in machine tool holders, promoting stability during operation and facilitating efficient chip removal for cleaner results.

Advantages

This carbide drill bit offers exceptional durability and heat resistance, allowing it to maintain its cutting edge even during prolonged use in tough materials. The high-quality carbide construction minimizes tool wear and reduces the frequency of replacements, which enhances overall productivity in manufacturing processes. Its design optimizes the drilling process by providing excellent centering capabilities and reducing vibration, resulting in high-quality bores that meet strict industrial standards.

Suitable for

• Precision drilling in steel and alloyed metals
• Industrial manufacturing and machining centers
• Applications requiring consistent hole diameter and depth
• High-volume production environments

When it may not be suitable

This drill bit is not recommended for use with handheld power drills, as the carbide material is brittle and requires the high rigidity and stability of a CNC machine or drill press to prevent breakage. It is also not intended for drilling soft materials like wood or plastic, where specialized geometry is required to prevent clogging.

Key specifications

• Diameter: 6.80 mm
• Drilling depth: 5xD
• Shank type: HA8
• Material: Solid carbide

How to use

To achieve optimal results, ensure the drill bit is securely clamped into a high-precision tool holder. Before starting the drilling process, verify that the workpiece is firmly fixed to the machine table to prevent movement. Use appropriate cooling and lubrication fluids to manage heat generation and assist in chip evacuation. Always start with a pilot hole if necessary and maintain consistent feed rates and spindle speeds recommended for carbide tooling to maximize the lifespan of the bit.

What to consider before purchase

• Compatibility with your machine tool holder system
• The hardness of the material being drilled
• Requirement for a rigid, vibration-free setup
• Need for appropriate cooling equipment

Usage recommendations

Always inspect the drill bit for signs of wear or chipping before each use. Replace the tool immediately if performance drops to avoid damaging the workpiece or the machine spindle.
