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

Bosch SpeedX 5/8 in. x 21 in. SDS-Max Rotary Hammer Bit is built for professionals who demand fast, reliable drilling through concrete and masonry with an SDS-Max hammer. Crafted from durable steel and sized for deep holes, this bit helps you tackle anchor installations, conduit runs, and more with fewer passes.

Key features

  • Diameter: 5/8 in. for common concrete anchor holes
  • Overall length: 21 in. to reach deep into concrete walls and slabs
  • Flute length: 16 in. for efficient material removal and reduced clogging
  • Shank: SDS-Max to fit compatible hammer drills
  • Material: Steel for rugged, long-lasting performance
  • Style: SDS-Max
  • Packaging: Carded, single piece

Why choose SpeedX? Bosch's SpeedX line is engineered to optimize fast drilling in hard masonry. The combination of SDS-Max compatibility and a purpose-built flute geometry means you can punch through concrete faster while maintaining bit life and consistency. The 21" length gives you reach in deep pours and thick walls, or long anchor holes, without losing rigidity.

Best uses and scenarios

  • Drilling anchor holes in reinforced concrete for suspension systems, electrical and plumbing installations
  • Running conduit or pipe through concrete or brick walls
  • Creating passage holes in masonry for fixtures, fasteners, or renovations

Practical tips for optimal results

  • Use with an SDS-Max hammer and maintain steady, controlled pressure; let the bit do the work
  • Periodically pause to clear dust and prevent overheating during long drilling sessions
  • Clear the flute after drilling to preserve performance and reduce binding on subsequent holes

Designed for professionals and serious DIYers tackling heavy masonry tasks that require deep, precise holes with dependable performance.

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.
