Both HSS and Cobalt drill bits have their strengths, and choosing the right one can make all the difference in your project’s outcome. For general-purpose drilling, you can’t go wrong with HSS. But when the job requires tackling tougher materials, Cobalt drill bits are the powerhouse you need.

The choice between HSS and Cobalt drill bits depends largely on the material you're working with and the frequency of your drilling projects.

If you’re working with tougher materials like stainless steel or cast iron, Cobalt drill bits are the superior choice. Their enhanced durability and heat resistance make them ideal for heavy-duty jobs that demand precision and longevity.

When it comes to drilling through various materials, choosing the right drill bit is crucial for both efficiency and quality of work. High-Speed Steel (HSS) and Cobalt drill bits are two of the most popular types for professional and DIY users alike. But what’s the difference, and when should you use one over the other? Let’s break it down.

HSS drill bits are the workhorse of the drilling world. They are made from carbon steel combined with alloys like chromium and vanadium, which give them their high durability and strength. HSS bits are designed to drill through softer materials, such as wood, plastic, and softer metals like aluminium and brass.

Cobalt drill bits are essentially HSS drill bits with an added 5-8% cobalt content mixed into the steel. This makes them even harder and more resistant to heat. Cobalt bits are specifically designed for drilling harder materials like stainless steel, cast iron, and other tough alloys.
