📘 Overview
The Digga RC8 is a rock/earth combination auger bit using B7 taper teeth for all-conditions drilling from earth to medium rock — designed for 4.5–15T excavators (heavier duty than RC6) machines with a 1-3/4" hex (thicker flights than A8) hub. The taper tooth system (TTD outer + TTS inner) provides clean holes in soft earth and clay while maintaining ripping ability in shale, caliche, and fracturable rock. PADLOC/TRULOC compatible. Made in Dyersville, Iowa, USA.
⚙️ Key Features
- RC8 | 1-3/4" hex (thicker flights than A8) hub | 60" OAL OAL | For 4.5–15T excavators (heavier duty than RC6)
- TTD (outer) + TTS (inner) MFT taper teeth — all conditions earth to medium rock
- PADLOC/TRULOC tooth system — tool-free field replacement
- Compatible drives: Digga 7DDS–12DDS series
- Made in Dyersville, Iowa, USA
🔑 Benefits
- All-conditions taper teeth eliminate bit swaps when ground conditions vary between earth and rock
- TTD/TTS taper system uses 1-step knock-in/knock-out — faster field changes than PADLOC in high-cycle rock drilling
- MFT tungsten on both outer and inner teeth provides maximum fracturing capability at all positions
- RC series covers earth to medium rock — not designed for very hard rock (use DR series for hard rock)

❓ FAQs
|
Q: RC8 vs A-series (earth only)?
RC8 uses taper teeth for combined earth-to-rock performance. A-series (A4/A6/A8) uses flat chisel teeth for earth only. For mixed conditions, RC8 eliminates bit swaps. |
|
Q: RC8 vs DR series (hard rock)?
RC8 handles earth to medium rock with taper teeth. DR series uses rotating carbide picks for fracturable to very hard rock. Choose RC8 for mixed conditions; choose DR for predominantly hard rock. |
|
Q: What replacement teeth?
TTD-3 outer and TTS-3 inner. Sold separately on eskidsteer.com. |
|
Q: Drive compatibility?
Requires Digga 7DDS–12DDS series — confirm your drive model and output hub match before ordering. |
|
Q: What pilot?
Contact eskidsteer.com or Digga for the specific pilot part number for this series. |
