Strong, reliable, and built for tough digging — the perfect auger bit for posts, trees, fences, and poles.
This BEFCO 12" x 36" Auger Bit is engineered for durable performance when you need to dig clean, consistent holes for fence posts, light poles, trees, or vineyard stakes. Its 12-inch diameter and 36-inch length strike a balance between manageable size and sufficient depth for most standard post-hole applications.
Thanks to its double-flight, fully welded flighting and a reinforced collar at the gearbox mount, this auger resists bending and stands up to repeated use — even in tough or compacted soil. It’s designed to fit a wide range of machines (100 through 400 series of compatible diggers), offering broad compatibility across common post-hole digger setups.
If you’re setting up fences, planting trees, or installing poles, this auger gives you a dependable, heavy-duty option that simplifies soil removal and ensures uniform holes every time. Its replaceable knives and point make maintenance straightforward, helping you keep it working reliably for years.
12" Diameter × 36" Depth
Ideal for standard post-hole work — deep enough for most posts, yet compact enough for easier handling and machine compatibility.
Fully Welded Double Flighting
Double-spiral, welded flighting ensures efficient soil removal and reduces risk of distortion under load, delivering consistent performance even in dense soil.
Reinforced Gearbox Collar
Extra strength at the mount point improves stability and longevity, especially when digging through hard or compact soil.
Replaceable Knives & Point
Wear items — like cutting knives and the auger point — can be replaced instead of replacing the whole auger, minimizing downtime and maintenance cost.
