In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

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.

About Product Overview

Engineered for serious metalwork, the Milwaukee 1/2 in. x 18 in. High Speed Steel Drill Bit with a 3-Flat Shank delivers dependable performance when you need clean, deep holes in tough materials. The coated finish helps resist heat and wear, extending bit life in demanding shop or on-site applications.

  • Size and geometry: 1/2" diameter, 18" overall length, 4" flute length, 1/2" shank with a 3-flat shank design for enhanced torque transfer and slip-resistant chuck grip.
  • Material and finish: High Speed Steel (HSS) with a protective coating to minimize heat buildup and extend cutting life during repetitive drilling.
  • Packaging: Carded packaging for easy visibility and handling on the shop floor.
  • Purpose: Built for deep metal drilling tasks where reach and reliability matter—from steel plate and structural metal work to automotive fabrication.

What makes this drill bit stand out is the combination of long reach and secure shank design. The 18" overall length lets you tackle deeper holes without repositioning equipment, while the 3-flat shank ensures your drill chuck maintains a confident grip under heavier feeds and torque. The coating reduces heat and wear, giving you more holes per bit and less downtime for bit changes.

Ideal for professionals and serious DIYers who frequently drill into metal, the Milwaukee 1/2" x 18" HSS drill bit shines in:

  • Deep-hole projects in steel, aluminum, and other metals where standard bits fall short on reach.
  • Industrial fabrication, automotive repair, and construction tasks that demand durable, long-lasting tooling.
  • Situations requiring precise starts and minimal wandering, thanks to the 3-flat shank's improved chuck engagement.

Practical tips to maximize performance: secure your workpiece, use cutting oil or lubricant to reduce friction, start with a pilot hole if drilling in thick material, and maintain a steady feed to minimize deflection. When you need reliable depth and control in metal drilling, this Milwaukee bit is a dependable choice that pairs legendary durability with practical, real-world usefulness.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
