Power Your Digging Auger

The power is in your hands. It’s important to make sure you have the proper drill for your Power Planter® auger and your project. The right drill or power engine helps you get the best possible performance out of your auger – and and can extend the life of your drill.

The chart below shows the minimum suggested drill voltage requirements for various hole sizes and depths.

Please note: This Auger Guide contains general recommendations. Power requirements may differ based on soil type and project specifications. These are our suggestions based on decades of user feedback. Holes 4 inches or wider will require a tube extender to dig deeper than 28 inches. We strongly advise using a drill with an adjustable clutch to prevent any kickback when you encounter a rock or large root. Scroll down for additional safety tips.

Power Requirements by Diameter

2″ Diameter
  • Minimum power requirement for 7” length = 14V cordless drill. Hard compacted soil may require 18V or more
  • Minimum power requirement for 24” or greater length = 18V – 20V cordless drill.
  • For mass planting, use a cordless drill with a side handle.
  • Longer length augers tend to benefit from higher voltage power drills.
3“ Diameter
  • Minimum power requirement for 7” length = 14V cordless drill. Hard compacted soil may require 18V or more
  • Minimum power requirement for 24” or greater length = 18V – 20V
  • For mass planting, use a cordless drill with a side handle.
  • Longer length augers tend to benefit from higher voltage power drills.
4“ & 5“ Diameter
  • For minimal planting, use a cordless drill with a side handle.
  • Minimum power requirement for loose soil and holes less than 12 inches deep = 18V – 20V
  • Minimum power requirement for heavy clay or compacted soil or holes deeper than 12 inches = 60V
  • See safety tips below.
7“ Diameter
  • We recommend using a 60V cordless drill with this diameter.
  • For minimal planting, use a cordless drill with a side handle.
  • See safety tips below.
8“ & 9“ Diameter
  • We recommend using a 60V cordless drill with this diameter.
  • For minimal planting, use a cordless drill with a side handle.
  • See safety tips below.

Important Safety Tips

READ YOUR SPECIFIC DRILL MANUFACTURERS SAFETY MANUAL FIRST. THEY SUPERCEDE ANY OF THESE GENERAL RECOMMENDATIONS.

  • Do not use earth augers with impact driver drills, drill bit extensions, sockets or quick attach chucks.
  • Avoid using corded drills or any drill that does not have a clutch. Start with a low clutch setting then gradually add more resistance. 
  • Always set the drill to the lowest speed setting. 
  • Always use two hands when digging with a drill. A drill with a stability handle is ideal.
  • Always use ANSI Z87.1 eye protection and proper respiratory protection. 
  • Keep hands and body clear of sharp edges and moving parts.
  • Read instructions and  manuals before operating these products.
  • If your drill is feeling hot after extended use, let it rest for 10-15 minutes to cool off before continuing.
  • Contact your local utility companies to identify underground electrical, water, or gas lines before any digging.

How to Choose the Best Drill for Digging

At Power Planter, we’re dedicated to making the highest-quality augers to help you tackle tough gardening and landscaping jobs with ease. Choosing an auger drill that delivers enough strength to dig through your specific soil can play a significant role in the success of your gardening project.

If you’re looking for the best drill for hole boring, consider these factors:

  • Power supply: A corded model means you don’t have to worry about running out of juice, but a cordless one gives you the ability to work anywhere on a property. Modern battery technology provides enough power for heavy digging. Always use a drill with an adjustable clutch.
  • Speed: The more RPM the tool delivers, the less torque. This might make a difference when digging through dense soils, where torque can be important. Always use a tool with a slow setting or “drill mode” for the highest torque and least amount of kickback.
  • Amperage: The higher the amperage, the more powerful the drill. If you’re using a longer bit, make sure you have enough strength to drive it. See our chart above.
  • Variable speed: If the power tool you choose has variable speed, it can be very useful for auguring around a property. That’s because variable speed allows you to control the amount of torque the motor produces.
  • Reverse: Switching into reverse mode can be convenient for easily removing the auger from the hole you’ve just dug.
  • Keyless chuck: This feature allows you to switch between augers quickly, if needed.
