## Summary description

The ALPEN HSS Cobalt twist drill bit is a high-performance tool designed for drilling into hard materials, including stainless steel. Featuring a 5mm diameter and 86mm length, it adheres to the DIN 338 RN standard. The 3-flat shank ensures a secure grip in the drill chuck, preventing slippage during operation. This short, robust drill bit provides excellent heat resistance and durability for professional metalworking applications.

## Long description

The ALPEN HSS Cobalt twist drill bit is a high-performance precision tool engineered for demanding drilling tasks in hard and alloyed materials. With a diameter of 5mm and a total length of 86mm, this drill bit is manufactured to meet the rigorous DIN 338 RN standards, ensuring consistent quality and dimensional accuracy. The inclusion of a 3-flat shank design provides a superior grip within the drill chuck, effectively eliminating slippage and maximizing torque transmission during intensive drilling operations.
Advantages
This drill bit stands out due to its high cobalt content, which significantly enhances heat resistance and structural integrity when working with tough metals. The robust construction minimizes the risk of breakage, while the specialized geometry allows for efficient chip removal and reduced friction. By utilizing the 3-flat shank, users benefit from increased stability and safety, as the bit remains firmly locked in place even under high pressure. Its durability ensures a longer service life compared to standard high-speed steel bits, making it a reliable choice for continuous professional use.
Suitable for
Drilling into stainless steel and acid-resistant steels
Working with cast iron and alloyed steels
General metalworking and industrial maintenance
Precision drilling in hard materials requiring high heat tolerance
When it may not be suitable
This drill bit is specifically optimized for metalworking and may not be the most efficient choice for drilling into soft materials like wood or plastic, where standard HSS bits are often more cost-effective. It is also not intended for masonry or concrete applications, as the cutting edge is designed for metal shear rather than impact drilling.
Key specifications
Diameter: 5mm
Total length: 86mm
Material: HSS Cobalt
Standard: DIN 338 RN
Shank type: 3-flat shank
How to use
To achieve the best results, ensure the drill bit is securely tightened in the chuck, aligning the flat surfaces with the chuck jaws. Begin drilling at a lower speed to establish a pilot point, then gradually increase the speed according to the material hardness. It is highly recommended to use a suitable cutting oil or cooling lubricant to maintain the temperature of the bit, which preserves the cutting edge and prevents overheating during deep or repetitive drilling.
What to consider before purchase
Verify the compatibility of the 3-flat shank with your existing drill chuck
Ensure the 5mm diameter meets your specific hole size requirements
Consider the material hardness of your workpiece to ensure cobalt performance is necessary
Usage recommendations
Always wear appropriate eye protection and secure the workpiece firmly with clamps before starting the drilling process to ensure operator safety and hole precision.
