Product Information

Full details

The Roughneck Dual-pivot Post Hole Digger is designed for professional contractors and DIY enthusiasts who need to dig precise, narrow holes for fence posts or deck foundations. Its primary benefit is the unique dual-pivot mechanism, which allows the jaws to close by pushing the handles together, drastically reducing the effort required to extract soil and lowering the amount of concrete needed for backfilling. While its specialized design is highly efficient for narrow, deep holes, users should note that the fixed 115mm diameter may be restrictive for larger footing requirements.

FAQs

What is the maximum hole diameter?

The bucket has a fixed diameter of 115mm.

Is this tool suitable for rocky ground?

The hardened steel blades are durable enough for compacted soil, but it is not intended for prying large boulders out of the ground.

How long are the handles?

The total length of the tool, including the handles, is 1.50 meters.

Does it require lubrication?

Yes, periodic application of machine oil to the pivot point will ensure smooth operation and prevent corrosion.

Can the blades be sharpened?

The blades can be maintained with a metal file if they show signs of wear after heavy usage.

Does the dual-pivot mechanism make the tool heavier?

While the mechanism adds some complexity, the use of tubular steel keeps the overall weight manageable for manual operation.

Troubleshooting

Jaws are difficult to open or close

Clean debris from the pivot point and apply a light machine oil to the hinge assembly.

Blades feel dull or struggle to penetrate soil

Inspect the blades for caked-on clay or small rocks; if the steel is dulled, use a fine file to touch up the edge.

Handles feeling loose during operation

Check the connection points and pivot bolts to ensure they are properly tightened and free of obstruction.

Pros and Cons

Pros

  • Reduces the amount of concrete needed due to narrow hole diameter
  • Requires less physical exertion than traditional scissor-style diggers
  • High-strength hardened steel blades ensure longevity
  • Offset handles prevent handle clashing during use

Cons

  • Fixed 115mm diameter limits use for larger structural posts
  • Requires more clearance for the pivot mechanism compared to narrow manual spades
  • Not suitable for extremely large boulder-filled ground

Setup, Compatibility & Care

This tool comes fully assembled and ready for immediate use. To maintain the digger's integrity, ensure the blades are cleaned of excess dirt and debris after every use to prevent corrosion. For long-term storage, apply a light coat of machine oil to the pivot points to ensure smooth action and protect the hardened steel blades from rust. Store the tool in a dry shed or garage. While the blades are hardened, avoid using the digger as a pry bar to remove large, embedded rocks, as this can put unnecessary stress on the pivot assembly.
