Properties of cobalt drills

Cobalt drills (so-called "cobalts") are drills made of HSS high-speed steel with the addition of cobalt. The admixture of the cobalt alloy is in most cases 5%. This composition translates into extreme hardness of the drill. Compared to other types of drills, HSS cobalt models are characterized by very high resistance to high temperatures and abrasion. The addition of cobalt also increases the service life. Due to its unique properties, cobalts are perfect for long-term work and demanding projects. The special shape of the spiral accelerates the removal of spoil.

The use of cobalt drills

Cobalt drills are used for drilling holes in metal, stainless steel, cast iron, titanium, cast steel, graphite, aluminum, plastics and other very hard materials. They blunt much slower than drills without cobalt alloy reinforcement, which is why they are used in more difficult working conditions. They significantly improve drilling and reduce the feed cutting force. They are mainly used by professional users in industrial projects. They are also the basic equipment of every locksmith's shop. The drill belongs to the accessory category. Works in conjunction with a suitable drill.

Cobalt drill sets and single drills

Cobalt drills are available as single products and in sets of several, a dozen or even several dozen elements. It is worth choosing a set when you need drills of different diameters for your projects.
