- 🔥 The step drill bit is made from upgraded high speed steel characterized by well-balanced toughness, wear resistance and red hardness properties for better and faster hole -drilling performance. The cobalt coating makes the drill bit more durable so that it can last for years with uncompromised quality.
- 🔥 The spiral dual-flute design prevents metal fillings from flying around and clears chips faster thus it can drill more smoothly without heating up.
- 🔥 The rapid strike tip drills twice as fast as the average step drills and can drill acrylic, PVC, wood, aluminum and iron sheets up to 0.2’’ in thickness.
- 🔥 CORTOOL drill bit is bigger in size so it can drill holes with larger dimensions.
- 🔥 10 hole sizes: 1/4; 3/8; 19/32; 3/4; 1'; 1'3/16; 1'3/8; 1'5/8; 1'3/4; 2'.
