Diameters are available from 4 inches to 48 inches. And we offer all the most preferred connecting collar sizes and configurations: 2-inch round, 2-9/16-inch round, 2-inch hex, and 2½-inch hex. Our medium-duty earth auger bits, besides being remarkably affordable, are construction-grade bits designed, engineered, and manufactured for the typical jobs your mini excavator handles. For more difficult digs, where a more aggressive approach is needed, you can’t go wrong with our heavy-duty industrial-grade bits. But, then, you’ll never go wrong with any bit we make. That’s because we make them as we make every component of our earth augers: to last. We start, of course, with the finest materials. Then we apply our design, engineering, and manufacturing expertise to turn out earth augers of exceptional strength and integrity – earth augers that’ll hold up to years of hard use. Just ask those who’ve used them. Contributing to the strength and durability of our earth auger bits is the way we attach the flighting. Whereas a number of competitors simply stitch-weld the flighting to the center tube, we fully weld ours in place. No short cuts for us! You’ll be happy to know too that we make a full line of earth auger wear components for replacement or upgrading. Most are kept in stock at all times so we have what you need when you need it. Included in our inventory are a variety of tooth and center point, or fishtail, upgrades with hardfaced and even carbide options. Here’s something else you’ll like: we can customize any of our earth auger bits to handle the unique digs your mini excavator takes on.
