Spiral-cut 9-inch auger for reliable deep-hole digging — ideal for fence posts, posts for decks or poles, and other heavy-duty soil work.
The BEFCO 9in x 36in Auger Bit – Double Flight | Fits 100–400 is built to attach to BEFCO MOLE series post-hole diggers (models 100, 200, 300, 400). It’s engineered for demanding ground-boring tasks — whether you’re installing fence posts, setting posts for signage or barns, or digging holes for planting large trees and shrubs.
With a robust double-flight design, this auger moves soil out efficiently, making each dig cleaner and faster. Because it’s built for the MOLE series, it integrates seamlessly with the digger’s gearbox and PTO drive to deliver reliable performance mile after mile.
Thanks to fully welded flighting and a reinforced mounting collar, the auger withstands heavy use and resists stress or fatigue — reducing downtime and maintenance. Replaceable knives and a fish-tail point make sure you can maintain cutting performance and extend the working life of the bit. It’s a practical, workhorse tool for contractors, farmers, landscapers, and anyone needing consistent, powerful digging for posts, poles, or plantings.
Double-Flight Spiral Design
Dual spirals lift and eject soil quickly and efficiently — reducing clogging and speeding up the digging process compared to single-flight augers.
Fully Welded Flighting & Reinforced Collar
Durable construction resists bending or warping, giving you long-lasting reliability on repeated digs in tough soil.
Replaceable Knives and Fish-Tail Point
Cutting edges and point are serviceable, so you can refresh the bit’s performance without replacing the entire auger — extending tool life and reducing cost over time.
Direct Fit for BEFCO MOLE 100–400 Series
Specifically made to fit all 100, 200, 300, and 400-series post-hole diggers from BEFCO — plug-and-play compatibility ensures easy installation and reliable drive performance.
Ideal for Fence Posts, Decks, Poles, and Tree Plantings
The 9″ diameter holes are well-suited for standard 6×6 posts or similar structural needs, making it a versatile choice for construction, fencing, and landscaping projects.
