Dormer Standard Soil Augers
The Dormer General Purpose Auger(SOS) is our most popular auger. Its general purpose design will handle most soil conditions – including very sandy soils. In stiff dry clay, penetration can be improved by adding a little water to the hole. The Dormer General Purpose Auger is a 2 slot, 2 cutter auger with a spiral tip design.
Dormer General Purpose Auger - Extra Bite
The Dormer General Purpose Soil Auger with extra bite (SOD), was developed to achieve extra penetration in hard clay soils. Whilst the main body of the auger is the same as the General Purpose Auger, the larger, coarser tooth design allows the user to auger in zones other augers can't penetrate.
Dormer Gravely Soils Auger
Similar to the General Purpose Auger, the Dormer Gravely Soils Auger has been specially designed to perform better in gravely soil conditions. Not restricted to gravely soil types the Dormer Gravely Soils Auger will handle most soil conditions. In stiff dry clay, penetration can be improved by adding a little water to the hole. The Dormer Gravely Soils Auger is a 2 slot, 2 cutter auger with a spiral tip design.
Dormer Sand Auger
The Dormer Sand Auger (SA) was originally designed to sample for minerals in beach sands but is now used extensively for drilling and sampling in very sandy friable soils. The Dormer Sand Auger has bite! A 75mm diameter sand auger will penetrate 30cm in approximately four revolutions, filling the auger head. In good conditions, one person can auger to 10m in under an hour.
Dormer Sticky Clay Auger
The Dormer Sticky Clay Auger (SOC) has been designed to allow the user to quickly penetrate clayey soils. The new wider side openings, and streamlined design of the cutting tip allows for quick sample removal and easy cleaning as well as faster cleaner sampling in clayey soils.
Dormer Jarret Auger
The Dormer Jarret Auger (JA) has been designed for the taking of small samples. Available in 50mm, 75mm or 100mm head only, the Jarret Auger is a small light weight auger and requires a seperate Auger extension and T-handle. Unlike other auger styles, the Jarret Auger will cause a large amount of mixing within a sample, however the auger teeth ensure the Jarret Auger will break through ground other augers can't.
Dormer Spiral Auger
The Dormer Spiral Auger (SP) has been deigned to punch through hard compacted soils or decomposed rock. They drill faster and are stronger than the General Purpose Augers, but require greater care for accurate sampling. Available in either a large spiral (1m) or small spiral (30cm) and mounted on a tubular steel shank, the Dormer Spiral Auger allows you to penetrate layers unreachable with other auger types.
