Our set has been manufactured in the latest technology in which durable drill bits are manufactured.
HIGH SPEED STEEL (HSS) is a material that is used in the manufacture of machine bits and blades. Often used in powerful saws and drills.
This technology replaced the earlier 40s with the production of high carbon steel. HSS is able to withstand higher temperatures than high carbon steels, allowing higher drilling and drilling speeds without sacrificing rigidity.
That's why this technology is called HIGH SPEED STEEL!
