Special Features

  • HSS Titanium Coating: Our high-speed steel drill bits, fortified with a titanium coating that makes the drill bit harder than a typical HSS bit, can reduce the friction drill, and perform well in heat, corrosion, and rust resistance.
  • Precision-Engineered Design: Two-flute spiral grooved design deburrs chips, dust and debris for clearance and smooth cutting. The 118° split point tip drill reduces friction, pressure, and heat, making the drill bits long-lasting and efficient.
  • Wide Application: Our step drill bit can process different diameter holes, and can be used on materials such as metal heavy-duty, iron, aluminum, brass, plastic, aluminum alloy, wood, plastic, etc. Suitable for home DIY and general use.
  • Quick Change: The 1/4-inch hex shank fits easily and securely into all power tools to prevent slippage and shedding during rotation.
  • 31 Step Sizes: 13 step drill (1/8, 5/32, 3/16, 7/32, 1/4, 9/32, 5/16, 11/32, 3/8, 13/32, 7/16, 15/32, 1/2-inch) 6 step drill (3/16, 1/4, 5/16, 3/8, 7/16, 1/2-inch) and 12 step drill (3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8-inch)
