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

Irwin Turbomax 29/64 in. x 5-5/8 in. High Speed Steel Drill Bit with a straight shank is designed to deliver dependable performance across metal, wood, and plastic projects. The 3/8" shank fits standard drill chucks, providing stable grip and consistent torque for clean, true holes from start to finish. This bit’s generous overall length and precise flute geometry make it a versatile choice for both shop work and home projects.

  • Material: High Speed Steel (HSS) for durability and reliable performance across common drilling tasks
  • Drill Size: 29/64" (11.5 mm) — a mid-range hole diameter handy for hardware mounting and metal fabrication
  • Shank: Straight 3/8" shank compatible with most standard drill chucks
  • Length: 5-5/8" overall length with a 4-3/16" flute length for deeper holes without compromising rigidity
  • Packaging: Carded, single-piece packaging from the Irwin Turbomax family

Why this drill bit stands out

  • Versatile for metal, wood, and plastics, making it a reliable go-to for quick metal repairs, cabinetry assembly, and DIY projects
  • The Turbomax line is built for consistent hole quality and durable performance, helping you avoid wandering or chatter even when drilling tougher materials
  • Long flute length provides the reach needed for deeper holes in thicker stock or recessed spaces, expanding its practical applications
  • Reliable Irwin quality you can trust in professional setups or serious DIY workshops

Practical tips for best results

  • Choose the appropriate speed and feed rate for the material: slower speeds for metal, moderate for wood, higher for plastics—maintain steady pressure
  • Lubricate when drilling metal to extend bit life and reduce heat buildup; wipe away chips frequently to prevent binding
  • Keep the bit perpendicular to the workpiece and secure the material to minimize wandering
  • For deep holes, periodically retract the bit to clear chips and prevent clogging

Ideal for professionals and serious DIY enthusiasts who need a single, dependable mid-range drill bit that handles metal and beyond with precision. With the Irwin Turbomax 29/64 in. drill bit, you gain consistent performance, durable construction, and a hole quality you can count on project after project.

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.
