The carbon steel market is poised to grow by 699.35 MT during 2020-2024 progressing at a CAGR of almost 8% during the forecast period." (Source: Business Wire)

This is what we are seeing all across the industry; day after day new emails from vendor's telling us that their prices are rising, every order we make for materials needs to be revised because the last price is no longer valid, and for good reason. The cost of steel materials has been steadily increasing throughout 2020, and it unfortunately has not slowed into 2021. The reduced capacities of companies in this industry due to Covid-19 health and safety regulations continues to have an impact. As a result, we are forced to increase our list pricing for 2021 and add a steel surcharge to off-set the rising costs that is projected to continue this year. We apologize for any inconvenience this may have on our close and prospective customers. We we will do what we can to keep our prices low when the opportunities are found, but right now we are left with little options.

Thank you for your understanding and continued support.


Product overview

Eterra Earth Auger Bits


The Eterra Auger Bit is designed for all your earth drilling conditions. If your conditions are steadily rough, consider adding Eterra's Tungsten Carbide Fishtail and Tungsten Carbide Teeth for longer life and better bite. These are some of the toughest and most reliable bits in the industry, and we would encourage you to just read the reviews. From the cast heavy duty drive heads to the thick walled tubing and forged cutter holder, these bits get the job done when you need them most.

Pricing Shown is for a 4" Bit. Larger bits and additional options add to price.

A note about Eterra's auger design. Eterra designs based on the toughest criteria and extensive experience. Many people think that a double flighted auger is better because it will be stronger. Eterra has designed a single flighted auger and a forged drive head so that the strength question is not an issue. Eterra is confident their heads will outlast any auger that has double flighting. The Eterra flighting design allows the auger to clear faster. Double flighting in a dirt design just clogs and causes the auger to carve the hole out so it will be oversized and jammed up with debris. This results in less productivity and higher costs due to having to put more concrete into the hole because of the larger size. The more you study these designs, the more you will come to trust Eterra as the leader in intelligent and performance based product design.

Do not use Earth Auger Bits on solid surfaces like concrete or asphalt driveways. For solid surface conditions choose a specialized rock auger bit.
