High Speed Steel Versatility
Our step drill bits are constructed from traditional HSS combined with a titanium nitride 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.
Unique 2 Flute Spiral Design
Two flute spiral 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.
