Irwin 88710 SPEEDBOR Spade Bit, Impact Accessible
The Irwin SPEEDBOR Spade Bit series, including model 88710, is a family of flat wood boring bits engineered for fast, clean drilling through wood using standard corded drills, cordless drills, and impact drivers. This line is available in three sizes — 1-3/8" x 6", 5/8" x 16", and 15/16" x 6" — giving pros and DIYers a range of diameters and lengths for different boring-depth and hole-size needs. Every SPEEDBOR bit in the lineup shares the same next-generation design: a patented Blue-Groove cutting edge for aggressive chip removal, a chamfered cutting edge for added durability, an optimized point tip for reduced splintering, and a reinforced shank built for fast, aggressive cutting.
Key Features
- Available Sizes: Choose from 1-3/8" x 6", 5/8" x 16", or 15/16" x 6" to match the hole diameter and boring depth required for the job.
- Impact Accessible: The shank design allows every size in the lineup to be driven with impact drivers in addition to standard corded and cordless drills, adding jobsite versatility.
- Optimized Point Tip: Wider and longer than previous-generation IRWIN spade bits, the tip helps minimize wood splintering and gives better control over drilling speed.
- Patented Blue-Groove Design: The Blue-Groove cutting edge opens up a large cutting area that aggressively clears wood chips for faster, cleaner holes.
- Chamfered Cutting Edges: Chamfered edges increase cutting-edge durability, helping each bit resist wear and hold an effective edge over more holes.
- Reinforced Shank: A reinforced shank is built to withstand fast rotational speeds and aggressive cutting pressure without flexing or failing.
- 2X Performance: Together, these upgrades let the SPEEDBOR Spade Bit lineup cut twice as fast and last twice as long as earlier IRWIN spade bit generations.

Irwin 88815 – Frequently Asked Questions
1) Can Irwin SPEEDBOR spade bits be used in an impact driver, or do I need a drill?
Both. The SPEEDBOR spade bit shank is impact accessible, so it runs in an impact driver as well as standard corded and cordless drills. That is the practical difference from older spade bits with a plain hex that was not rated for impact drive.
2) What sizes does the Irwin SPEEDBOR spade bit come in?
Three sizes: 5/8 x 16 inch (model 88710), 15/16 x 6 inch (88815), and 1-3/8 x 6 inch (88822). The second number is overall bit length, so the 5/8 inch is the long-reach option for drilling through stacked framing members or reaching into a bay, while the two larger diameters come in the standard 6 inch length.
3) Which spade bit size should I use for running Romex or conduit through studs?
For electrical rough-in through framing, the 5/8 x 16 inch SPEEDBOR (model 88710) is the one most electricians reach for, because the 16 inch length lets you bore through multiple studs or angle into a stud bay without an extension. If you need a larger clearance hole for a bundle or a larger raceway, step up to the 15/16 inch or 1-3/8 inch, both in a 6 inch length.
4) Is the Irwin 88710 spade bit sold individually or as a set?
Individually. Each SPEEDBOR size is a single bit, not a multi-piece set, so you order only the diameters you actually bore.
5) Will a spade bit give me a clean hole in finish work, or should I use something else?
The SPEEDBOR has an optimized point tip, wider and longer than earlier Irwin spade bits, to cut splintering and give better speed control, but it is still a flat wood boring bit built for rough carpentry, framing, remodel work, and clearance holes. For cabinet-grade exit holes or boring hardware pockets in finished faces, a Forstner or an auger with a backer board is the better choice.
6) What is the Blue-Groove design on the Irwin SPEEDBOR and does it actually matter for repetitive drilling?
Blue-Groove is a patented cutting edge geometry that opens a larger cutting area to clear chips aggressively, which is what keeps the bit from packing up and stalling when you are boring hole after hole in framing lumber. Paired with chamfered cutting edges for edge durability and a reinforced shank that resists flex under hard feed pressure, Irwin rates the line to cut twice as fast and last twice as long as its earlier spade bit generations.
7) Does the Irwin SPEEDBOR spade bit need a battery or any power accessory?
No. It is a non-energy-using cutting accessory with no battery included and none required; you supply the drill or impact driver.
