Feature(may vary by option.)

●Durable Titanium Coated Bits ----- 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 titanium coating makes the drill bit more durable so that it can last for years with uncompromised quality.
●Jam-Free Performance ----- The dual-flute design prevents metal fillings from flying around and clears chips faster thus it can drill more smoothly without heating up.
●Universal Compatibility ----- 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.
●Larger Size ----- Our drill bit is bigger in size so it can drill holes with larger dimensions.
●One Bit for All ----- The bit comes with 12 hole sizes: 6mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm. , saving you time and efforts to change bits, quadrupling your drilling efficiency compared to competition.

Convenient & Accurate

  • Laser-engraved reference marks on each bit offer superb convenience and accuracy, ideal for drilling large and small-diameter holes in metal and plastic. For high-efficient drilling, thickness of sheet metal shall be less than that of each step.

Smooth & Clean Drilling

  • X-type openings design to facilitate the removal of cutting waste when drilling, preventing iron chips or sawdust from scattering and ensuring sleek & accurate drilling.

Distinct Shank Design

  • Compatible with 1/4, 3/8, 1/2 electric drills or bench drills, but only work for sheet metal with hardness below HRC30, aluminum or plastic.
