          High Speed Steel Durability

          Our step drill bits are constructed from traditional HSS combined with a titanium coating to make them even more durable. This also proves the capability and durability of the drill to last through multiple drillings on surfaces such as: plastic, aluminum, copper, stainless steel, and so much more.

          Two flute design also lets the material particles escape easily for a much more clean drilling operation. With each step, you can feel the drill bit stop so you never drill bigger than you need to.
