Compatible earth-auger powerheads
  • Check shaft shape, pin arrangement and the powerhead instructions, not diameter alone.
  • This is an auger attachment, not a 1/2-inch drill-chuck accessory.
  • Arrange utility locating before digging and assess the ground for obstructions.

A closer look

A narrower hole starts with the right bit

A 4-inch diameter can suit smaller hole requirements when the project specification permits it. Choose the required finished hole size first, then confirm that the powerhead can use this bit.

A closer look

Fit the powerhead, then assess the ground

The 3/4-inch connection is one compatibility check. The retention hardware, powerhead limits and ground conditions matter too. A carbide tip does not turn an earth auger into a rock drill.
