## Long description

The Format Twist Drill Bit HSS-Co Cylindrical 8.5 mm is a high-performance cutting tool designed for professional workshop and industrial applications. Manufactured from premium high-speed steel with a cobalt alloy content (HSS-Co), this drill bit offers superior heat resistance and extended durability compared to standard steel bits. Its robust construction ensures reliable performance and precise hole creation in demanding metalworking environments.
Advantages
The incorporation of cobalt in the HSS-Co material composition significantly improves red hardness, allowing the drill bit to maintain its cutting edge even under high temperatures generated during deep or continuous drilling tasks. The cylindrical shank ensures a secure and stable fit in standard drill chucks, promoting accurate alignment and reducing runout. This tool delivers clean, burr-reduced holes in tough materials, minimizing the need for secondary finishing operations and increasing overall operational efficiency.
Suitable for
Drilling alloyed and unalloyed steels
Working with stainless steel and acid-resistant metals
Professional workshop and industrial manufacturing tasks
Precision metal fabrication and maintenance operations
When it may not be suitable
This drill bit is not recommended for drilling soft non-metallic materials such as wood, plastics, or rubber, as the geometry and material are specifically engineered for metal. Additionally, it is not optimized for masonry, concrete, or other mineral-based building materials.
Key specifications
Diameter: 8.5 mm
Material: High-speed steel with cobalt content (HSS-Co)
Shank type: Cylindrical
Application range: Metal, alloyed steels, stainless steel
How to use
Ensure the drill bit is firmly secured in a compatible drill chuck before operation. Select an appropriate drilling speed based on the material being processed, and apply steady, moderate pressure to maintain cutting efficiency. The use of a suitable cutting fluid or lubricant is strongly recommended during operation to dissipate heat, prolong the lifespan of the tool, and achieve optimal surface finish quality.
What to consider before purchase
Verify that your tool chuck accommodates an 8.5 mm cylindrical shank
Confirm that your primary application involves hard metals or stainless steel
Ensure adequate lubrication and cooling equipment is available for optimal performance
Usage recommendations: Always wear appropriate personal protective equipment, including safety glasses and gloves, when performing metal drilling operations. Regularly inspect the cutting edges for wear or damage to ensure consistent precision and prevent tool breakage.
