Product details

The Cobalt spiral drill bit with a diameter of 4.5 mm from kwb is a high-quality tool specifically designed for machining metal and other demanding materials. This drill bit is made from a cobalt-alloyed HSS steel alloy, which ensures high heat resistance and durability.

The drill bit is ideal for machining alloyed and unalloyed steel, stainless steel, gray cast iron, steel castings, bronze, and plastics. The industrial quality of the drill bit makes it a reliable choice for professional applications as well as for DIY needs.
