Einhell 18V Power X-Change Cordless Fence Post Auger (150mm) – brushless post hole borer, tool body only

The essentials

If you’re drilling fence post holes (or digging planting holes that need real torque), a cordless auger can save you a surprising amount of hassle. This Einhell cordless fence post auger is designed for “earth boring” without dragging extension leads around the garden. On paper, it’s aimed at DIYers and regular gardeners who want something more practical than a manual post-hole digger, but still prefer a controlled, tool-like setup rather than something overly specialised.

You also get flexibility in how the auger runs thanks to three modes: anti-clockwise, clockwise with ECO power mode, and clockwise with HIGH power mode. That sort of control matters because soil isn’t consistent—what works in one patch may feel sluggish or overpowered in another, so having options is a sensible idea.

Key features that affect real use

The headline here is the brushless motor. Brushless motors are typically chosen for better efficiency and a longer service life versus brushed designs, so the expectation is lower wear over time and steadier performance during repeated drilling. It’s paired with a durable gearbox housing built for demanding work, which is exactly what you want when you’re pushing an auger into compacted ground.

Then there’s the physical stability: the post hole digger uses a steel frame with a double handle. For this kind of job, comfort and control matter as much as raw power. When you’re drilling, you don’t want the tool to feel like it’s twisting out of your stance.

A practical detail: the tool body includes an adaptor and accessories, but it’s sold as “cordless post auger only”. That means you must already have an 18V Li-ion battery and charger compatible with the Power X-Change system (not included).

What stands out (and where it can fall short)

What stands out most is the combination of three operating modes and a brushless motor in a cordless format. If you’ve ever tried to drill in the worst spot in the garden—where a power cable is either in the way or far too short—going cordless is genuinely one of those “why didn’t I do this sooner?” upgrades.

That said, there are limitations. If you don’t already own the right Power X-Change battery and charger, the overall cost can climb once you factor in the missing battery ecosystem. Also, this is a 150mm auger application (as stated), so if you frequently need much larger holes or very stubborn ground conditions, you may find you need to check whether the offered auger size and modes match your specific jobs.

Who it’s for (and who should be cautious)

It makes sense if you’re regularly doing fence post installations, boundary works, or frequent garden digging where having a drill-like tool improves speed and consistency. It suits people who are happy to follow a straightforward approach: choose the right mode (ECO for lighter work, HIGH when you need more drive, and anti-clockwise when the task calls for it), then drill with a steady stance using the double handle.

It might not be the best match if you only need the odd hole once or twice a year. In that case, renting or using a more manual approach could be more cost-effective, especially if you’d still need to buy the battery and charger from scratch.

Worth considering if you already have Power X-Change kit and simply want the auger tool body to add to your collection.

Tech specs

• Type: Cordless fence post auger / post hole borer
• Motor: Brushless
• Power system: 18V Power X-Change (battery and charger required, sold separately)

In the field: a simple example of use

Imagine you’re putting up a run of fence panels. You mark your post positions, then start drilling. For soil that’s looser near the surface, you can try the ECO power mode first to get the auger biting smoothly. As the hole deepens and the ground firms up, switching to HIGH mode can help maintain progress. When you need to clear or reposition, the anti-clockwise mode can help you control how the auger disengages, rather than fighting it while it’s still loaded with soil.

Final verdict

Is it worth it?

Buy it if you want a cordless, brushless fence post auger that focuses on practical control (three modes) and stability (steel frame with double handle), and you already have the matching 18V Power X-Change battery + charger. It’s the kind of tool that tends to earn its keep when you’re doing repeated outdoor drilling where extension leads get annoying fast.

Don’t buy it if you’re starting from zero with Power X-Change and you only need a couple of holes—because this is tool body only, the “missing battery” factor can push the total up. It may also not suit you if your requirements regularly sit well outside what a 150mm auger application typically covers.

Small FAQ

What does “tool body only” mean?

It means the cordless post auger is supplied without the 18V battery and charger, you need compatible Power X-Change 18V Li-ion battery electronics and a charger separately.

How many drilling modes does it have?

The auger has three modes: anti-clockwise, clockwise in ECO power mode, and clockwise in HIGH power mode.

Is it better than using a corded drill?

Cordless is often more convenient for garden work because it avoids power cords and likely makes setup faster, especially in awkward parts of the yard. The trade-off is you must have the right battery.

Does the brushless motor matter?

It’s designed to offer improved performance and a longer service life over a brushed motor concept, which is useful for repeat jobs rather than one-off use.
