## Summary description

The GTV HT6D129 is a high-quality 8.0 mm metal drill bit featuring a 5% cobalt (Co5) alloy composition.

It is an essential tool for professional metalworking and DIY projects, ensuring clean holes and long-lasting performance in demanding industrial or home workshop applications.

## Long description

The GTV HT6D129 8.0 mm metal drill bit is a professional-grade cutting tool engineered for high-performance drilling in demanding materials. Crafted with a 5% cobalt alloy (Co5), this drill bit provides superior heat resistance and structural integrity, allowing it to maintain its sharpness even when working with hardened steel and other challenging metal surfaces. Its robust construction ensures consistent results and extended tool life, making it a reliable choice for both industrial metalworking and intensive home workshop tasks.
Advantages
The primary benefit of this cobalt-alloy drill bit is its exceptional thermal stability, which prevents the bit from softening or losing its edge during prolonged drilling operations. The high-quality material composition reduces the risk of breakage and wear, ensuring that each hole is drilled with precision and clean edges. Furthermore, the design promotes efficient chip removal, which helps maintain drilling speed and accuracy while minimizing friction and heat buildup during operation.
Suitable for
Drilling into stainless steel and alloyed steel
Working with cast iron and non-ferrous metals
Professional metal fabrication and repair
Demanding DIY metalworking projects
When it may not be suitable
This drill bit is specifically optimized for metal applications and may not be the most efficient choice for drilling into soft materials like wood or plastic, where standard high-speed steel bits are often sufficient. Additionally, it is not intended for use on masonry, concrete, or stone surfaces, as these materials require specialized carbide-tipped bits to prevent premature damage to the cutting edge.
Key specifications
Diameter: 8.0 mm
Material: High-speed steel with 5% cobalt (Co5)
Application: Metal drilling
Heat resistance: High
How to use
To achieve the best results, secure your workpiece firmly in a vice or clamp to prevent movement during the drilling process. Start by marking the center point of the hole to ensure accuracy. Use a steady, moderate pressure and a lower rotational speed when drilling into hard metals to prevent overheating and to extend the life of the bit. It is recommended to use a cutting fluid or oil to lubricate the contact point, which helps dissipate heat and improves the quality of the finish.
What to consider before purchase
Ensure your drill chuck is compatible with an 8.0 mm shank diameter
Verify the hardness of the material you intend to drill
Consider using a pilot hole for increased precision
Usage recommendations
Always wear appropriate eye protection and safety gear when operating power tools. Regularly inspect the drill bit for signs of wear or dullness to maintain optimal performance and safety.
