by Soil boring augers are manual drilling tools used for digging holes in dirt, clay, soft rock and other loose materials. Consisting of a hollow drill bit and extension rods, soil boring augers enable users to efficiently bore circular holes of varying depths.
Components of a Dirt Hole Auger
A standard Dirt Hole Auger set contains the following main parts:
– Drill bit: The circular cutting head at the bottom which breaks up and removes soil/material. Bits come in various sizes depending on the hole diameter required. Common diameters are 3-12 inches.
– Extension rods: Hollow steel rods that connect the drill bit to the handle above ground. Rods come in lengths of 2-4 feet and can be assembled in series to reach greater depths.
– Handle: The upper section that allows the user to manually rotate the auger and bore the hole. Most have T-handles for improved leverage and control during operation.
– Retaining bolts: Used to securely fasten additional extension rods together as the hole gets deeper. Heavier gauge bolts may be needed with longer rods.
– Carry/storage case: Portable cases allow Dirt Hole Auger to be transported and organized between job sites. Foam inserts protect parts during transit.
Applications for Soil Boring Augers
From farming and landscaping to construction and utility work, dirt hole augers have widespread commercial and DIY applications:
– Planting trees/shrubs: Holes of 6-12 inches are dug for setting transplants or seedlings.
– Fence post installation: Augers bore uniform 8-10 inch holes for concrete or wood posts to stand upright.
– Drainage projects: Narrow ditches and perforated drain lines require 4-6 inch diameter holes.
– Irrigation systems: Smaller augers install lateral water lines and sprinkler heads below ground.
– Septic/leach field: Large 12-20 inch holes accommodate absorption field layouts and distribution boxes.
– Utility construction: Electrical, telephone and cable companies rely on augers for underground installations and repairs.
– Oil/gas exploration: Geothermal and mineral prospecting often utilizes specialty auger drilling equipment.
Operating a Soil Boring Auger
Follow these basic steps when manually operating a soil boring auger:
- Assemble the drill bit, extension rods and handle as needed based on hole depth. Hand tighten retaining bolts securely.
- Place the auger assembly vertically into the starting hole position over the desired location.
- Rotate the handle clockwise while applying downward pressure to bore into the ground. Rods will naturally feed downward.
- Periodically remove cut soil from inside rods using a trowel or scoop. Extract fully when the hole is complete.
- For holes over 4 feet deep, partial disassembly may be needed as you work down in stages adding rods.
- Lubricants like water or oil can ease cutting if the soil becomes dense or caked on the bit edges.
- Upon reaching total depth, simply unscrew rods and bit to finish the hole for its intended purpose.
Choosing the Right Soil Boring Auger Size
When selecting a soil boring auger, the most important specification is the diameter of the cutting bit. This will determine the width of the resulting hole. Other considerations include:
– Soil conditions: Rocky or dense soils may require larger bits for easier cutting/removal of material.
– Use of hole: Place accordingly for things like fence posts, tree trunks, drain lines based on their diameters.
– Project scope: One-time jobs may only need a basic kit. Contractors prefer heavier-duty, multi-size augers.
– Equipment access: Choose an auger small enough to fit through gates, between rows on small plantings, etc.
With proper technique and maintenance, dirt hole augers can reliably tackle a variety of digging projects through all soil types. Their versatility has made augers essential manual tools in agriculture, construction, utilities and more. With the right model for your job, expect soil boring augers to provide years of dependable service.
