Each bit in this set is manufactured using High-Speed Steel (HSS), a material renowned for its exceptional strength and heat resistance. This property enables the drill bits to maintain their sharp edges for longer periods, resulting in faster drilling speeds and increased productivity.

The sharp cutting edges of these drill bits are coated with a Titanium Nitride (TiN) layer. This coating not only enhances the wear resistance of the bits but also reduces the friction between the bit and the materials being drilled, thus preventing the bits from overheating and prolonging their lifespan.

Designed for use with high-speed drills, these step drill bits provide superior drilling performance even in tough and hard materials such as metal, wood, and masonry. Their robust construction ensures that they can withstand the rigors of heavy-duty usage, delivering reliable and consistent results every time.
