The step drill bit is made out of upgraded high speed steel characterized by well-balanced toughness, wear resistance and red hardness properties for better and faster hole -drilling performance. The titanium coating makes the drill bit more durable in order that it may last for years with uncompromised quality.
The twin-flute design prevents metal fillings from flying around and clears chips faster thus it may drill more smoothly without heating up.
The rapid strike tip drills twice as fast as the typical step drills and will drill acrylic, PVC, wooden, aluminum and iron sheets as much as 0.2’’ in thickness.
Our drill bit is greater in size so it may drill holes with larger dimensions.
