## Long description

The ALPEN HSS-ECo step drill bit is a professional-grade cutting tool engineered for precision drilling in a range of diameters from 4mm to 12mm. Constructed from high-quality cobalt-alloyed high-speed steel, this tool provides exceptional thermal resistance and structural integrity, making it suitable for demanding metalworking tasks. Its multi-step design allows for drilling, deburring, and countersinking in a single continuous operation, significantly improving workflow efficiency when working with thin materials.
Advantages
The primary benefit of the ALPEN HSS-ECo step drill bit is its superior material composition, which includes cobalt for increased hardness and heat resistance during high-speed operation. The geometry of the bit is optimized to produce clean, burr-free holes, reducing the need for secondary finishing processes. Its robust construction ensures a long service life even when subjected to the rigorous demands of industrial metal fabrication, providing consistent performance across various metal types.
Suitable for
Sheet metal processing
Drilling into stainless steel
Working with non-ferrous metals
General steel fabrication
Creating holes for cable glands or fasteners
When it may not be suitable
This drill bit is not intended for use on extremely thick materials that exceed the length of the individual steps. It is also not suitable for drilling into hardened steel or masonry, as these materials require specialized carbide-tipped tooling to prevent premature wear or breakage of the bit.
Key specifications
Diameter range: 4mm to 12mm
Material: Cobalt-alloyed high-speed steel
Design: Multi-step conical geometry
Application: Metal drilling and deburring
How to use
To use the ALPEN HSS-ECo step drill bit, secure the workpiece firmly to prevent movement during the drilling process. Insert the bit into a standard drill chuck and ensure it is tightened securely. Begin drilling at a low to moderate speed, applying consistent, light pressure. Allow the cutting edges to do the work, and avoid excessive force to prevent overheating. Use a suitable cutting oil to extend the life of the bit and improve the quality of the finish, especially when working with stainless steel.
What to consider before purchase
Verify the maximum material thickness compatible with the step height
Ensure your drill machine supports the required shank size
Confirm the compatibility of the bit material with your specific metal type
Usage recommendations
For optimal performance and longevity, always use a high-quality cutting lubricant when drilling stainless steel and maintain a steady, controlled feed rate to avoid work hardening the material.
