Material
Available in blue painted steel (shown below), aluminium or stainless steel. All augers come with the option of fine or coarse threaded connections. The standard augers come painted for protection. Stainless Steel version available for critical sampling and acid cleaning.

Size
The Dormer equipment is sized in accordance with the nominal Outside Diameter (OD) of the tube or pipe it is made from. Each different type of auger has different cutter designs and therefore
cuts a slightly different sized hole. The Sand Augers cut approximately 5mm larger than the nominated size and the Soil Augers cut approximately 10mm larger. Our standard nominal sizes are 50mm, 62mm, 75mm & 100mm and some other sizes as special orders. The auger heads are generally 450mm long with a tubular shank to make the overall length either 1.0 or 1.5 metres. If size (diameter) is an important factor with your requirements please discuss this with us. Most of the other equipment sizes relate to their OD.

BENEFITS

All Dormer augers' cutters are case hardened in our furnace as standard, or a hot spray-on tungsten carbide hardening is available as an optional extra and some can have solid carbide pieces attached.

The augering equipment is available with either of two types of threaded connection; the standard "fine" thread is 5/8 inch (appox.16mm) Whitworth (formerly known as LD thread) and the "Coarse" thread is 1&1/8 inch (approx.28mm) Acme (formerly known as HD thread). Other connections like the notched bayonet coupling with captive sleeve and the hexagonal fittings with pins are also available, POA.

Auger Heads

SOS - General Purpose Auger
The most popular auger which is a general purpose design to handle most soil conditions, even very sandy soils. In stiff dry clay penetration can be improved by adding a little water to the hole. It is a 2 slot, 2 cutter, with a spiral tip design. Available in 50, 62, 75 & 100mm diameter x 1m or 1.5m long.

SON - General Purpose & Gravely Soils Auger
An older design, this auger performs slightly better in gravely soils. It is a 2 slot 2 cutter, without spiral tip design.Available in 50, 62, 75 & 100mm diameter x 1m or 1.5m long.

JA - Jarret Auger
For taking small samples but may be subject to sample mixing causing contamination. Available in 50, 75 or 100mm head only (extension required) with choice of fine, coarse or pipe threads.

SP - Spiral Auger
Used to drill hard compacted soils or decomposed rock. They drill faster and are stronger than the soil augers but require greater care for accurate sampling. They come in 50mm and 62mm diameters and either full length spiral or a 300mm spiral piece mounted on a tubular steel shank. All are available in 1.0 metre or 1.5 metre lengths.

SA - Sand Auger
Originally designed to sample for minerals in beach sands but now are used extensively for drilling and sampling in very sandy friable soils. A 75mm diameter sand auger will penetrate 30 cm in about 4 turns, which fills the auger. In good conditions, one man can drill 10 metres in an hour, two men can drill 20 metres in two hours and 40 metres takes most of the day.

SOC - Sticky Wet Clay Auger
A fast penetrating auger for sticky clays with a design to enable easier cleaning and emptying. Available in 48mm or 63mm diameter x 1m or 1.5m long.

SOD - Extra Bite Soil Auger

This new soil auger was developed to achieve extra bite in hard clay soils and by doing so requires extra effort to turn it. The body of the auger is the same as the SOS soil auger. The new cutter design has superior penetration capabilities in normal soils.

Works well in conditions from silty sand clays through to very tight clays.

Options: Sizes (100mm not yet available); Length; Thread; Hot spray-on hardening.
