📘 Overview
The Digga A8 Earth Auger Bit suits excavators up to 15 tons, using a 1-3/4" hex hub for the greater torque and down-pressure outputs of this machine class. Same proven double-start, single-carry flight design as the A4 and A6 — scaled for larger machines. Multi-facet tungsten (MFT) teeth throughout extend performance to soft fracturable rock. PADLOC/TRULOC tool-free tooth system. Made in Dyersville, Iowa, USA.
⚙️ Key Features
- A8 Series | 1-3/4" hex hub | Excavators up to 15T
- MFT (multi-facet tungsten) teeth — earth, clay, soft fracturable rock
- Double-start, single-carry flight — shallow pitch, superior soil retention
- PADLOC/TRULOC — tool-free field tooth replacement
- Multiple diameters available
- Made in Dyersville, Iowa, USA | Digga — since 1981
🔑 Benefits
- 1-3/4" hex handles greater torque without pilot stress concentration at corners
- MFT teeth extend versatility to soft rock without requiring a separate bit
- Proven Digga flight geometry scaled to heavier machine class ensures consistent performance
- PADLOC/TRULOC field tooth changes keep large machine drills productive

❓ FAQs
|
Q: A8 vs A6?
A6 is for 4.5-8T machines. A8 is for machines up to 15T. Both use 1-3/4" hex but A8 has heavier construction for the greater torque of 10-15T class drives. |
|
Q: A8 vs RC8?
A8 uses flat chisel teeth for earth and clay. RC8 uses taper teeth (thicker flights) for combined earth-to-rock drilling. A8 is more economical for pure earth applications; RC8 for mixed conditions. |
|
Q: What pilot does A8 use?
Contact eSkidSteer at 866-757-8337 for the specific pilot part number for the A8 series. |
|
Q: What diameters are available?

|
Q: What drive is needed for the A8?
