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

Upgrade your drill kit with the Irwin Turbomax 31/64 in. x 5-7/8 in. L High Speed Steel Drill Bit with Straight Shank. This single-piece bit is built to handle precision work in metal and wood, delivering clean holes and long tool life.

What makes it stand out

  • Material: High Speed Steel for durability and heat resistance during metal drilling.
  • Size and reach: 31/64" drill size with a 3/8" straight shank; flute length 4-3/8" and overall length 5-7/8" for mid-depth holes and good balance in handheld or bench-mounted drills.
  • Shank type: Straight shank for universal chuck compatibility.
  • Packaging: Carded, single-bit packaging for easy store display and identification.
  • Brand: Irwin Turbomax, a trusted name in performance drill bits.

Ideal uses and scenarios

Designed for a variety of tasks in home shops and professional workshops:

  • Metalworking: create precise holes in steel, aluminum, and other metals when paired with appropriate cutting speed and lubrication.
  • Woodworking: drilling clean pilot holes and through-holes in soft and hardwoods, reducing split-out with a sharp edge.
  • Maintenance and fabrication projects where a reliable 31/64" bit is required to match fasteners or hardware.

Practical tips for best results

  • Start with a lower speed and a steady feed to minimize deflection and heat buildup.
  • Use cutting oil or appropriate lubricant when drilling metal to extend bit life.
  • Let the bit do the work—avoid excessive pressure and clear chips frequently to maintain cutting efficiency.
