Irwin 3041003 Speedbor Max 3PC 5/8″ – 1″ Spade Bit Set

Built for fast, clean wood drilling, the IRWIN 3041003 SPEEDBOR MAX set includes three tri-flute spade bits sized for common rough-in and framing tasks. Each bit uses a full screw-point tip to pull itself into the cut, reducing push force and helping maintain speed in studs, plates, and joists. Three cutting spurs scribe the perimeter for cleaner entry and reduced breakout on the exit side, especially in softwood and plywood. A grooved 1/4″ quick-change hex shank seats securely in standard drill chucks and bit extensions, and the enlarged shank design improves durability under load. Manufactured from high-speed steel, these bits handle repetitive drilling and jobsite wear while keeping chips moving out of the hole. With 5/8″, 3/4″, and 1″ sizes, this set covers common cable, pipe, and hardware clearances in one compact package—ideal for framers, electricians, plumbers, and shop users who need speed and consistency from their spade bits.

The self-feeding tip reduces fatigue on overhead or ladder work, while the tri-flute body moves chips out of the way to limit binding in wet or dense stock. Electricians and plumbers get cleaner holes that make cable pulls and pipe passes easier, and carpenters appreciate the consistent finish when drilling through visible components. With three essential sizes and quick-change shanks that drop into a drill or impact driver, crews can move from layout to drilling without swapping tools. The high-speed steel build and thicker cutting edges stand up to repetitive boring, helping teams keep pace on rough-ins, decks, and shop tasks with fewer stalls and cleaner exits.
