About Product Overview

This Milwaukee 31/64" drill bit is built from cobalt, a step up from standard high speed steel when you're boring through tougher stock like stainless steel or heavy-gauge metal. Cobalt holds its edge longer under heat, so you spend less time stopping to resharpen or swap bits mid-job.

At 5.12" overall length with a 3/8" shank, it's sized for drill presses and heavy-duty drills where reach and shank compatibility matter. Sold individually on carded packaging, it's a straightforward replacement or addition to a metalworking bit set.

  • Drill size: 31/64"
  • Overall length: 5.12"
  • Shank diameter: 3/8"
  • Material: Cobalt
  • Sold individually, carded packaging

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.
