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
🔧 Machine Compatibility

Care & Maintenance
- Grease the drive unit gearbox per the manufacturer's schedule — typically every 8 hours of operation; a starved gearbox is the most common cause of drive unit failure
- Inspect bit carbide teeth after every use in rocky or abrasive soil — worn or chipped teeth increase drive unit load and reduce penetration
- Replace a worn pilot bit before the main teeth wear — the pilot centers the bit and prevents wobble that stresses the drive unit gearbox
- Check hydraulic hose connections at the drive unit before each use — hose chafing in tight soil is a common failure point
- Store bits vertically or with exposed carbide protected — storing lying flat with unprotected carbide causes chipping from incidental contact
How to Connect
- Attach auger drive head using Bob-Tach
- Connect high-flow hydraulic couplers (colour-coded on most brands)
- Verify rotation direction — auger should rotate clockwise when viewed from above
- Lower auger to ground and test rotation at idle before digging
⚠ Safety NoteAugers typically require 15-35 GPM — verify your machine's aux hydraulic flow before connecting
