## Long description

The ALPEN HSS Cobalt twist drill bit is a high-performance precision tool engineered for drilling into hard and demanding materials. Manufactured to DIN 338 RN standards, this 3x61mm drill bit features a robust cobalt-alloyed high-speed steel construction that provides superior heat resistance and extended tool life. The inclusion of a 3-flat shank ensures a secure, non-slip grip in standard drill chucks, allowing for consistent performance during intensive metalworking tasks.
Advantages
This drill bit stands out due to its exceptional thermal stability, which prevents the cutting edge from softening even when operating at higher temperatures during continuous use. The precision-ground geometry ensures accurate hole starting and clean drilling results, while the specialized flute design facilitates efficient chip removal, reducing the risk of clogging and overheating. The 3-flat shank design significantly improves torque transmission and prevents the bit from rotating within the chuck, providing enhanced safety and reliability for the operator.
Suitable for
Drilling into stainless steel and acid-resistant steels
Working with high-tensile alloyed steels
General metalworking in industrial and workshop environments
Applications requiring high precision and heat resistance
When it may not be suitable
This drill bit is specifically optimized for hard metals and may experience premature wear if used on abrasive materials like masonry, concrete, or stone. It is also not recommended for use on soft materials where standard HSS bits would be more cost-effective.
Key specifications
Diameter: 3 mm
Total length: 61 mm
Material: HSS Cobalt alloy
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 moderate speed, applying steady and consistent pressure. It is recommended to use a suitable cutting oil or cooling lubricant to maintain the temperature of the bit and extend its service life. Always ensure the workpiece is firmly clamped to prevent vibration or movement during the drilling process.
What to consider before purchase
Verify the chuck capacity of your drill to ensure compatibility with the shank design.
Assess the hardness of the material you intend to drill to confirm that a cobalt-alloyed bit is the correct choice.
Ensure you have the appropriate cooling lubricants available for metalworking applications.
Usage recommendations
For optimal performance and longevity, always maintain a low to medium rotational speed when drilling hard metals and apply consistent, firm pressure without forcing the tool.
