About Product Overview

Milwaukee's Thunderbolt black oxide drill bit is built for drilling into steel and other metals where a standard bit won't hold up. The black oxide finish adds heat and corrosion resistance, helping the bit run cooler and last longer under repeated use. A 3-flat shank grips securely in the chuck and resists slipping when you're pushing through tough material, and the 1/2" shank fits standard drill chucks even though the drill size itself is 11/16".

  • Drill size: 11/16"
  • Shank diameter: 1/2" with 3-flat shank design
  • Flute length: 3"; overall length: 6"
  • Finish/material: black oxide
  • Sold individually, carded packaging

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.
