Home \ Products \ Earth Auger Bits Earth Auger Bits Over the years, Premier has manufactured tens of thousands of earth augers to handle countless jobs. We offer everything from carbide-toothed, industrial-grade, heavy-duty auger bits to light-duty general-purpose auger bits. Our manufacturing capabilities are such that we can even create custom bits for you –designing and fabricating earth auger systems to your specifications, for your machines and your jobs.

Need a post hole digger for tractors? We’ve got it. Need a carbide bullet-tooth rock auger for skid steer loaders? We’ve got that too. We’ve also got long, fully flighted earth augers for deep-drilling excavator applications and all sorts of augers in between. With our augers, an equipment operator need never leave his seat to dig hundreds of holes a day, even in the toughest conditions. And that’s true whether he’s digging holes for fence posts, sign posts, post frame buildings, foundation footings, light and utility poles – or just about any other job where vertical or angled holes are required. Our single-flight medium-duty augers are an economical choice when soil conditions are light and usage is intermittent. Don’t let the price fool you, though; we build these augers with the same components and the same integrity we bring to their double-flighted counterparts. The cost savings come from the single-flight build. The overall length of these augers is 4 feet. Connecting collar sizes and configurations include 2-inch round, 2-9/16-inch round, and 2-inch hex. Normal stocking sizes are from 4 inches to 24 inches in diameter. Our medium-duty double-flight augers are the most common we build. Their double-flighted construction gives you more capability to move dirt out of a hole faster. We refer to these augers as our “CDF” line of earth auger bits. They’re great in digging conditions of light-to-moderate difficulty. We build them with a one-piece cast steel boring head that the replaceable teeth bolt onto. By using a casting, we can pitch the teeth at different angles for a more aggressive digging action. All our competitors use a flat piece of steel to hold the teeth on their standard augers. This restricts them to digging at only one angle. Premier augers can dig at any angle. We offer them in a 4-foot overall length with connecting collar sizes and configurations of 2-inch round, 2-9/16-inch round, 2-inch hex, and 2½-inch hex. Normally, we stock these in diameters of 4 inches to 36 inches. We also offer these “CDF” earth augers in standard lengths of 3 feet, 5 feet, and 6 feet. Our heavy-duty double-flight augers are ideal for tougher digging applications. We refer to these augers as our “CDC” line of bits. They’re built with a one-piece cast steel boring head, which holds the teeth at very aggressive angles. This makes them ideal for digging effortlessly into compacted or frozen soils – even in dirt and cobble mixes. The overall length of our heavy-duty double-flight augers is 4 feet. Connecting collars come in 2-inch round, 2-9/16-inch round, 2-inch hex, and 2½-inch hex configurations. Auger diameters typically stocked are from 4 inches to 48 inches. Standard lengths are 3 feet, 5 feet, and 6 feet. Our tree augers are the landscaper’s ideal labor-saving tool. We fabricate each of these augers with two different diameters of flighting. This produces a hole with a step, or taper, which allows space for the addition of compost or makes other soil enhancements possible prior to the tree being planted. An additional benefit of the tapered hole is that it helps eliminate air pockets typically produced when holes are dug with a conventional flat-bottom earth auger. We refer to these products of ours as “CDT” tree augers and build them in 18-, 24-, 30-, 36-, 42-, and 48-inch diameters. Their standard length is 4 feet, overall. And the collars for them come in 2-inch round, 2-9/16-inch round, 2-inch hex, and 2½-inch hex configurations. Our rock augers have carbide-tipped bits that – as the name implies – do some serious damage to rock. These are heavy-duty augers built to handle the toughest demands. We use thicker flighting and thicker center tubes on these models, then we hard-face all leading edges. The more down pressure you exert, the better they do. Diameters are available from 4 inches to 48 inches. The overall length of our rock augers is 4 feet. They’re also available in standard lengths of 3 feet, 5 feet, and 6 feet. Connecting collars are offered in 2-inch round, 2-9/16-inch round, 2-inch hex, and 2½-inch hex configurations. Whatever machine you’re outfitting, Premier can customize any of these bits for the job at hand. We offer all kinds of tooth upgrades and center points, or fishtails, as well, including hard-faced and even carbide options for all augers. Just tell us what you want, give us the specs, and we’ll produce it for you quickly, efficiently, and affordably in our Fort Wayne, Indiana, plant.
