## Summary description

The ALPEN HSS Cobalt twist drill bit is a high-performance tool designed for drilling into hard and alloyed steels. Featuring a 3-flat shank for secure chuck grip and a short design compliant with DIN 338 RN standards, this 8mm bit ensures precision and durability. Ideal for professional metalworking applications, it offers excellent heat resistance and efficient chip removal for demanding industrial tasks.

## Long description

The ALPEN HSS Cobalt twist drill bit, with an 8mm diameter, is a high-performance tool engineered for precision drilling in demanding metalworking environments. Manufactured to DIN 338 RN standards, this short-series drill bit features a robust cobalt-alloyed high-speed steel construction, providing exceptional heat resistance and structural integrity when working with hard and alloyed steels. The inclusion of a 3-flat shank ensures a secure, slip-free grip in standard drill chucks, enhancing stability and accuracy during operation.
Advantages
This drill bit excels due to its high-quality cobalt content, which maintains cutting edge hardness even at elevated temperatures generated during intensive drilling. The short design increases rigidity, reducing the risk of breakage and ensuring precise hole placement. The 3-flat shank design is specifically optimized to prevent the bit from rotating within the chuck, allowing for efficient torque transfer and safer operation in both handheld and stationary drilling machines.
Suitable for
Drilling into stainless steel and acid-resistant steels
Working with high-tensile alloyed steels
General metal fabrication and industrial maintenance
Precision drilling tasks requiring high stability
When it may not be suitable
This drill bit is not intended for drilling into masonry, concrete, or soft wood, as the geometry and material composition are specifically optimized for metal applications. Using this bit on non-metal materials may result in premature dulling or inefficient performance.
Key specifications
Diameter: 8mm
Material: HSS Cobalt alloy
Standard: DIN 338 RN
Shank type: 3-flat shank
Design: Short series
How to use
Insert the drill bit into the chuck, ensuring the three flat surfaces are properly aligned with the chuck jaws to maximize grip. Secure the chuck firmly. For optimal results, use a cutting oil or coolant to manage heat and extend the life of the bit. Apply steady, moderate pressure and maintain a consistent drill speed appropriate for the material hardness. Avoid excessive side pressure to prevent bit deflection or breakage.
What to consider before purchase
Verify the chuck capacity of your drill to ensure it accommodates an 8mm shank.
Ensure the material being drilled is compatible with cobalt-alloyed tools.
Consider the depth of the hole, as this is a short-series drill bit.
Usage recommendations
For the best performance and longevity, always use a low drilling speed when working with hard metals and apply consistent cooling lubricant to prevent overheating the cutting edges.
