FAQs
What is the best drill for a garden auger?
The best drill for a garden auger is typically a high-torque 18V or 20V cordless drill with a brushless motor. Augers require sustained power, and low-torque drills tend to stall or overheat. Look for a drill with:
-
Minimum 500–750 in-lbs torque
-
Brushless motor for better efficiency and longer runtime
-
½-inch all-metal chuck to hold thick auger shafts securely
-
Two-speed gearbox so you can run low RPM with high torque
-
Side handle for safety and better control
Models from DeWalt, Milwaukee, and Makita are commonly rated best for garden augers because they deliver enough torque to dig in clay, compact soil, and rocky areas without bogging down.
Can I use an auger bit in a cordless drill?
Yes, you can absolutely use an auger bit in a cordless drill—as long as the drill is powerful enough. An underpowered drill may stall, overheat, or drain batteries too quickly. A robust cordless drill with a ½-inch chuck is necessary because garden augers often have thicker shanks than wood-boring bits.
When choosing an auger bit for your drill:
-
Pick an auger between 1.5" and 4" diameter for most gardening tasks
-
Use low-speed mode to maintain safe torque
-
Hold the drill firmly with both hands, ideally with a side handle
-
Avoid high-speed drilling, which can cause kickback
In short: yes, it works—but the right drill makes all the difference.
What is the best cordless auger?
The best cordless auger is typically a dedicated battery-powered auger designed specifically for digging, such as those made by Earthquake or Landworks. These tools come with built-in motors and offer significantly more torque than a standard drill.
However, if you're referring to auger bits used with a cordless drill, then the best options are heavy-duty carbon-steel garden auger bits with hex shanks that won’t slip. Brands like Power Planter or K-Brands are excellent because they stay sharp, handle rocky soils well, and pair perfectly with high-torque cordless drills.
For most homeowners, a 3" x 12" or 4" x 16" auger is the sweet spot for planting bulbs, starter plants, or mixing soil.
Can I use my drill as an auger?
Yes, your drill can function like an auger when paired with the right auger bit. Many gardeners rely on drills because they’re lighter, more portable, and more affordable than full-size powered augers.
However, there are important safety considerations:
-
Use slow speed for better control
-
Grip firmly with both hands
-
Start drilling at a slight angle before going vertical
-
Clear soil from the bit frequently to prevent binding
-
Avoid using weak or compact 12V drills—they struggle in hard soils
With the right setup, your cordless drill becomes a highly effective small-duty auger for gardening, fence installation, and soil mixing.
Conclusion
Choosing the best cordless drill for a garden auger comes down to torque, durability, and control. A high-torque 18V/20V brushless drill paired with a quality auger bit transforms heavy digging into quick, effortless work. Whether you're planting, installing posts, or simply improving your garden soil, the right drill setup will save time, reduce strain, and deliver professional-level results. Happy digging!
