Description

A 15-inch auger bit isn't something most crews own outright — it's a tool you pull in for specific jobs and you want it to work right the first time. The Brave 15in 1-3/8in Hex Auger Bit is built around that reality. It uses a 1-3/8-inch hex drive, which is the standard connection on Brave's towable and walk-behind powerheads, meaning there's no adapter fumbling on the jobsite — it seats, locks, and goes.

The flighting is heavy-gauge formed steel, welded to a solid hex shaft. The carbide-tipped teeth cut through the mixed soils you'll find across central New Hampshire — everything from the sandy loam in the Merrimack Valley to the rocky, root-threaded ground you hit the minute you get north of the Lakes Region. At 15 inches, this bit is sized for 4×4 and 6×6 post installations, tree and shrub planting where root ball clearance matters, and deck footings where code requires a full hole rather than a driven stake. It's not a bit for close-quarters work — at this diameter, you're moving material, and you need the full powerhead torque behind it to do it cleanly.

The people renting this are typically residential contractors running fence lines, landscapers installing ornamental trees, and homeowners tackling pergola or deck projects who want cleaner results than a clamshell digger delivers. It also gets pulled by municipalities and utility crews for sign post placements along roadways. The common thread: a job where consistent hole diameter matters, and hand digging isn't a realistic option.

Because this bit is an attachment — not a standalone unit — you'll need a compatible Brave powerhead to run it. We carry those as well, so if you're booking the bit, ask about pairing it with the right powerhead at the counter. If you're not sure what your project calls for, the crew at our Tilton location can size it out with you before you load up.

For crews doing repeat installations — a 100-foot fence run, a full line of sign posts, a landscape planting plan — the math on renting vs. buying this kind of specialty tooling is straightforward. A 15-inch bit at this spec level isn't cheap to own, maintain, and transport for occasional use. Renting means you get a sharp, well-maintained bit every time without carrying inventory.

NorthPoint serves job sites across central and northern New Hampshire, and we stock a full range of landscaping equipment to go with attachment rentals like this one. If you're running a larger project and want to set up an account, the charge account application is straightforward and keeps billing clean across multiple rentals.

PRODUCT SPECIFICATIONS

This bit ships without a powerhead — confirm your drive unit compatibility before pickup. One-person operation with the appropriate powerhead; no CDL required for towing the walk-behind unit on standard trailer.

USE CASES

• Installing 6×6 deck footings where hand digging isn't practical
• Running a fence line through mixed NH soil — loam, clay, and gravel layers
• Planting balled-and-burlapped ornamental trees with consistent hole sizing
• Setting sign posts along road frontage or property lines
• Drilling pier holes for pergola or outbuilding foundations
• Prepping holes for gate posts or mailbox installations in hardpacked ground

FAQ

Can I rent just the bit, or do I need to rent the powerhead too? You can rent the bit on its own if you already own a Brave or compatible 1-3/8-inch hex powerhead. If you don't have a drive unit, we rent those as well — just let us know when you call or come in and we'll set you up with a matched pair. Running the wrong drive with a 15-inch bit at the wrong torque rating is how you break equipment and waste half a day, so it's worth a two-minute conversation at the counter.

What kind of ground will this bit struggle in? Any auger bit — including this one — will hit its limits in dense ledge, heavy cobble, or frost-hardened ground. In NH, that's a real consideration from November through April depending on the site. If you're hitting refusal at a few inches and the powerhead is bogging, you're likely on ledge or a boulder, and no bit size is going to solve that. For rocky soil with smaller stones and roots, this bit handles it well — the carbide tips are built for exactly that.

How deep can I go with a 15-inch bit? The standard bit reaches approximately 36–42 inches of usable depth depending on the model configuration. For deeper holes — say, frost-depth footings in northern NH — you'd want to ask about extension options. We can tell you at pickup whether extensions are available and compatible with the powerhead you're running.
