20 Best Drill Bit For 6061 Aluminum (2023 Updated)

6061 aluminum is a heat-treatable aluminum alloy that contains magnesium and silicon as its major alloying elements. Originally developed for the aircraft industry, it is now often used in marine, automotive, and structural applications.

Its ease of welding and corrosion resistance make it a popular choice for many projects.

When drilling into 6061 aluminum, it is important to use the correct drill bit. The recommended drill bit for 6061 aluminum is a cobalt drill bit. Cobalt drill bits are made of a harder metal than high-speed steel drill bits, and they have a higher heat resistance.

This makes them ideal for drilling into aluminum, as they will not overheat and damage the material.
