McMillen 20-Inch Auger Bit for Skid Steers
Overview
McMillen's 20-inch auger bit handles large-diameter structural footings, concrete pier holes, and major tree transplanting on full-size skid steers. At 20 inches, this bit requires a high-torque auger drive such as the McMillen X2475 or X3575. Carbide-tipped flighting delivers effective cutting through compacted soil, gravel, and mixed Canadian ground conditions. McMillen is a leading US auger manufacturer with established Canadian dealer presence through equipment dealers and specialty auger suppliers. Available through authorized McMillen dealers in Canada.

Is This Right For You?
✅ Buy if…
- You already have an auger drive unit and need the right bit for your soil type or hole diameter
- You drill specific hole sizes for fence posts, footings, or tree planting and need diameter variety
⛔ Skip if…
- You don't have an auger drive unit — a bit alone does nothing without a compatible drive motor
- Your soil is solid rock or hardpan — standard earth bits fail fast, you need a dedicated frost/rock bit
🔍 Also consider…
- Rock or frost auger bit if your ground is caliche, Shield rock, or frozen Prairie soil
- Auger drive unit if you don't yet have one compatible with your machine's hydraulic flow
Compatible with all skid steer brands and compact track loaders via universal SSQA quick attach. Mid-frame machines (S450–S650 class) are the most common fit.
