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

Meet the Irwin Turbomax 15/32 in. x 5-3/4 in. High Speed Steel Drill Bit with a Straight Shank—built for dependable, precise holes in metal and wood. Crafted from robust high-speed steel, this 1-piece drill bit is ready to tackle durable cutting tasks from the shop to the job site.

Designed for compatibility and versatility, it features a straight 3/8" shank and a total length of 5-3/4". The 15/32" drill size (0.46875") is ideal for larger pilot holes and clearance holes, while the flute length of 4-5/16" provides efficient chip evacuation and smoother cutting through tougher materials. The carded packaging keeps your tool organized and ready for quick selection when you need it most.

Why this drill bit stands out

The Turbomax line from Irwin is built for professionals who value reliability and precision. The combination of a robust high-speed steel core and a straight shank ensures straightforward use in standard chucks, reducing slippage and allowing consistent hole starts. At 5-3/4" long, this bit reaches deeper into workpieces without requiring excessive workholding adjustments, making it ideal for deep-hole tasks in both metal and wood applications.

Best use cases

  • Through-holes and clearance holes in mild steel, aluminum, and other metals
  • Large-diameter pilot holes in hardwood and softwood for cabinetry, framing, or furniture projects
  • Electrical and plumbing installations where deep, clean holes are needed

Practical tips for optimal results

  • For metal drilling, use light to moderate cutting speed and apply steady pressure to maintain a clean cut and extend bit life.
  • Clear chips frequently to prevent clogging and overheating—pause to back the bit out and remove debris as needed.
  • Keep the edges sharp and inspect the flute for wear; replace when cutting performance drops to maintain accuracy.
  • When drilling wood, consider a centered pilot hole to guide the bit and reduce tear-out on delicate grains.

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.
