Irwin SPEEDBOR Spade Wood Drill Bit 1-1/8 in x 6 in Pack of 5 - Faster

Our review of the Irwin SPEEDBOR Spade Wood Drill Bit 1-1/8 in x 6 in Pack of 5 finds it best for tradespeople and serious DIYers who need fast, repeatable bore holes in wood. The single biggest reason to consider these bits is the combination of a wide cutting area and the patented Blue-Groove scoop that aggressively removes chips so holes are completed much faster with less clogging. In short, this pack targets users who run through multiple holes and want a durable, impact-driver compatible spade bit that reduces time on routine framing and rough carpentry tasks.

Key Features

• 2X faster drilling: The large cutting area and optimized tip let users make more holes in less time compared with older spade bits.
• 2X longer life: Chamfered cutting edges and a reinforced design improve durability for longer runs between bit changes.
• Blue-Groove parabolic scoop: Patented groove quickly ejects wood chips so bits stay clear and drilling remains efficient on deep holes.
• Impact driver ready shank: The 1/4 in impact-rated shank fits impact drivers and helps control torque during aggressive drilling.
• Optimized point tip: A wider, longer point reduces splintering at the exit side and helps maintain drill accuracy in studs and framing timber.

Who It's For

These spade bits are aimed at framers, electricians, plumbers and carpenters who frequently bore through studs and dimensional lumber and value cycle speed and chip clearance. The pack of five keeps multiple bits on hand for jobsite rotation and replacement.

If fine finish work, precise bores for dowels, or countersunk, tear-free holes for trim are your top priorities, a brad-point or Forstner bit would be a better choice; the SPEEDBOR is optimized for speed and rough carpentry rather than delicate finish cuts.

Pros & Cons

Pros

• Fast hole cutting thanks to the aggressive cutting edge and chip removal design.
• Durable chamfered edges generally extend bit life for heavy use.
• Impact-rated 1/4 in shank works well with modern impact drivers and cordless drills.
• Pack of five provides immediate replacements and jobsite backup.

Cons

• Some customers report mixed durability and occasional early rusting, so bits may need drying or light oiling after exposure to moisture.
• Not intended for precision finish holes where a Forstner or brad-point bit is preferable.

Frequently Asked Questions

Can these bits be used in an impact driver?
Yes, they feature a 1/4 in impact-rated shank specifically designed for use with impact drivers and high-torque drills.

Will these bits reduce splintering?
The optimized wider, longer point tip helps minimize splintering compared with older spade bits, but for tear-free finish work a Forstner or brad-point bit is preferable.

Do they resist rust?
Bits have improved durability, but some customers report rusting when exposed to moisture; drying and light oiling after use will help prevent corrosion.
