About Product Overview

This Milwaukee Shockwave impact step drill bit is built to punch through sheet metal and thin stock without the bit skating or binding partway through the cut. The 1/4" hex shank fits straight into an impact driver, so you get the speed of impact-rated torque without needing a dedicated drill. High speed steel construction with a titanium aluminum nitride finish holds an edge through repeated holes and resists the heat buildup that dulls standard bits fast.

One bit covers a 3/16" to 1/2" range, which means fewer bit swaps when you're stepping up hole sizes in electrical boxes, HVAC ductwork, or gauge steel brackets. At 3.68" overall length, it's compact enough to work in tight bays and behind obstructions where a full-length bit won't clear. Good fit for electricians, HVAC techs, and metal fabricators who need one reliable bit for a range of hole sizes instead of a full index.

  • Drill size range: 3/16" to 1/2"
  • Overall length: 3.68"
  • Shank type: 1/4" hex, impact-ready
  • Material: high speed steel with TiAlN finish

  • Made in the USA

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
