Home \ Products \ Earth Auger Bits \ Excavator Earth Auger Bits Excavator Earth Auger Bits Premier makes virtually every kind of earth auger bit you could need for excavator use, whether you’re installing soundwall barriers, say, or doing foundation work or handling any other kind of commercial, industrial, or agricultural project. Specifically, we offer ... medium-duty double-flight auger bits - the cost-efficient, quality standard for most jobs, heavy-duty double-flight auger bits, designed to aggressively tackle the cruelest soil conditions, MD heavy-duty auger bits for use with high-torque drive units, and rock auger specialty bits with carbide bullet teeth thatt turn rock to dust in no time flat. You can get these excavator-perfect earth auger bits in lengths from 4 to 9 feet and in practically every diameter from 4 inches to 48 inches. We make the connecting collars for them too – in 2-inch round, 2-9/16-inch round, 2-inch hex, 2½-inch hex, 2-5/8-inch hex, and 3-inch hex configurations. You can be sure that every auger component we make is built to last through years of the heaviest excavator use. One thing we do to add strength and durability is fully weld the flighting to the center tube. Some competitors simply stitch-weld the flighting in place. That may be okay for conventional jobs and light use. But when the work is constant and the tasks are tough, stitch-welding tends not to hold. Premier’s fully welded flighting makes for a much more dependable auger. Of course, all augers eventually wear out or get busted up. So its nice to know you can get genuine Premier wear and replacement parts as well. And you can get them anytime, since we always keep a full complement in stock. Included in our inventory are all kinds of upgraded teeth and center points, or fishtails, with hardfaced and even carbide options for all augers. Many customers also hire us to make custom augers for their excavators. If a customized solution is what you need, just give us a call and we’ll work with you to devise the ideal auger for your unique application.
