Anatomy of an Auger

When you have been in the industry for as long as Champion Equipment, the pressure of keeping current in your industry can be overwhelming. If there is anything we have learned in six decades, it is that if you are leading the industry, you drive the innovation. Champion Equipment is hands down, the number one source for drilling tools and equipment in the country. Our proven track record is apparent in drill sites all over the world, as our tools are responsible for some of the most impressive drilling in the industry. We realize, however, that most of our success is due to the loyalty of our customers. Of course, it helps when you find a design that works, they tend to build loyalty. It is these loyal business owners that keep coming back year after year, that make what we do truly worthwhile.


An often overlooked part of an auger, drilling bucket or a coring tool are the teeth and bits. The teeth and bits almost exclusively provide the ground contact required for digging. The ease at which the bits chew through the material is due to the design, and design matters. At Champion Equipment, we stock a wide variety of teeth and tooth configurations. The true test of an auger, or any other digging tool for that matter, is the mounting of the tooth. Dirt augers tend to have a flat tooth that is reminiscent of an excavator or backhoe bucket. The tooth may be tipped with a carbide inlay for better wear. The extra cost of these teeth is well worth it, as they will last much longer than hardened teeth. A dirt setup generally includes a bit that features conical teeth or a centering bit in the middle.

Intelligent bit design from Champion Equipment.Conical teeth are used for when rock is going to be encountered. Typically, conical teeth are mounted at a much more downward angle than the flat, dirt teeth. Rock teeth are generally much more tool-like in nature than hardened flat teeth. First of all, they are shaped specifically for tearing and breaking rock, whereas flat teeth are engineered for scraping and digging. The cutting area is more spread out for precise control of the hole. Conical teeth are, many times, set into a circular mount. This allows for the tooth to rotate producing a grinding action that increases the ease of getting through hard rock.If you have ever tried to drill with a dull drill bit, even on a small scale, you know that the tip is one of the most critical parts of the process. The tooth configuration is directly responsible for the quality of our job. Choose the right tooth for the job, and while most teeth will perform in a variety of conditions, save yourself the extra work and pick the right tooth the first time. If you need guidance about which tooth configuration will work the best for your specific jobsite, please do not hesitate to give us a call. We have experts on staff that are ready and willing to help you answer any questions you may have. If you need a specialized, custom tooth or configuration for a job we can engineer the ideal auger with the perfect tooth set up. We do all of this in-house to save you money and cut out the middleman.


Auger flights are the backbone of any auger. The flights are critical to the efficient operation of the auger and provide a degree of support for the teeth. In order for the auger to perform as it should, the flight must be a continuous spiral, able to carry away the displaced material without clogging up. The flights generally have little to do with the digging action itself, but with compacting the sides of the hole and keeping the hole from collapsing. The angle of the flights is critical to the strength of the auger itself and providing downforce for effective drilling. The rise of continuous flight auger in the U.S. has prompted Champion Equipment to develop our own, proprietary designs. The continuous flight auger is specialized and we can either provide the tool you need or we can build you a specialized, meticulously engineered auger to fit your needs. A critical component of the continuous flight auger is the connector and the connector fittings. At Champion Equipment, we have developed a design that allows for greater strength when drilling, preventing downtime and costly repairs.

The Connector

The connector of the auger, or where it attaches to the drill pipe, is designed to provide a failsafe connection between the rig and the auger. Mounting configurations can vary dramatically between manufacturers and at Champion Equipment, we can retrofit any old or new auger to fit your machine. The structural integrity of the connector is critical to avoid losing your auger in a hole, costing time and money. We can custom engineer a specialized connector for you. Just give us a call and see what we can do for you!

At Champion Equipment, we could go on for hours about augers and we take great pride in providing our customers with the finest product available. When we sell you a piece of drilling equipment, we see it as a newly formed partnership, and you can alway count on us. Get started on your summer order today!
