Step Bits

Standard drill bits make holes of only one size. When contractors and DIYers need different sized holes for their projects, they must use a new drill bit for every hole diameter. Step bits allow you to drill up to 13 hole sizes without changing the drill bit, helping you finish projects faster.

Our Step Bits for Sale

Construction Fasteners and Tools has a wide range of step bits from reputable brands like Milwaukee Tool and IRWIN TOOLS. Our bits range from two to 13 steps so you can drill virtually any size hole you need. Our step bit options include:

  • Milwaukee® Step Drill Bits: These drill bits give you more control and a clean finish. The high-speed steel material is durable, and the black oxide coating is for corrosion prevention. The speed start tip penetrates the material faster to prevent bit walking.
  • Milwaukee® SHOCKWAVE™ Impact Duty™ Step Drill Bits: This step bit option prioritizes durability. The SHOCKZONE™ body minimizes shank breaks, and the titanium aluminum nitride coating helps the step bit last longer. The steps are laser engraved so you can identify which level you are on.
  • Milwaukee® Cobalt Step Drill Bits: Cobalt drill bits are made to last longer than similar bits. The Rapid Strike™ tip helps you start faster, while the small step increments drill smoothly through many materials.
  • IRWIN® Self-Starting Step Bits: Step bits by IRWIN TOOLS have a single-flute cutting edge for operator control through every step. The SpeedPoint® tip penetrates the material quickly, and the titanium nitride coating provides longevity.

Uses for Step Bits

When using a step bit, you can tap, drill and deburr materials without switching to another tool. When you touch the edge of the next step to the surface, the step bit deburrs the hole's edge, eliminating further prep work.

Step bits can drill shallow holes or make existing holes larger. Use step bits on thin materials like:

  • Sheet metal: Step bits are suitable for stainless steel sheets and nonferrous metals up to 1/8 inch thick.
  • Plastics: Use a step bit for acrylic, thermoplastic and thermosetting plastics, and plexiglass.
  • Steel sheets: Step bits can cut steel sheets up to 4 millimeters thick.
  • Wood: You can use a step bit on wood 4 millimeters thick or less.
  • Carbon fiber: Step bits can create a clean hole in carbon fiber without damaging the material.

Step bits are common in these sectors:

  • Electrical: Step bits can drill and deburr holes in panels, junction boxes and fittings.
  • Heating, ventilation, and air conditioning (HVAC): Installing HVAC equipment requires drilled holes, and a single step bit can yield a variety of hole sizes.
  • Automotive: The automotive industry uses step bits to install or repair car audio systems and auto bodies.
  • Construction: You can install cabinetry, plumbing fixtures, underfloor heating and electrical infrastructure with step bits.
