    Genuine Digga auger bit Includes pin, clip, teeth and pilot

    Overview

    The Digga RC8 is a taper tooth rock and earth combo auger bit — one bit for earth, clay and fracturable rock, rather than two bits for two jobs. It runs a 2.5 inch hex hub, with a 3 inch hex hub available as an option, suits Digga 9DDS through 12DDS drives, and is sold here in fourteen diameters from 8 to 60 inches on a 3 inch hex hub. Every bit comes with its pin, clip, teeth and pilot fitted.

    Key Features of the Digga RC8 Auger Bit

    • Combination rock and earth — the condition Digga builds this bit for
    • 2.5 inch hex hub, or 3 inch hex as an option
    • 60 in overall length on a 3 - 6.5 in pipe
    • Flights 3/8 in lead and 3/8 in carry
    • TTD tungsten taper teeth, with the PH-3, or PH-3XL above 30 inches
    • Maximum diameter 70 in in the Digga range
    • Suits 9DDS through 12DDS drives
    • True Cut design — Digga builds these bits so a 12 inch auger drills a 12 inch hole rather than an oversized one
    • Supplied complete with pin, clip, teeth and pilot

    Optimum Drilling Speed for the RC8

    Ground Drill speed (RPM)
    Earth 55-65
    Clay 45-55
    Shale / fracturable rock 25-45
    Heavy rock 10-25

    Digga publishes these speeds because running a bit too fast in hard ground wears teeth without cutting. If your drive has a two-speed shift, this table is what the low range is for.

    Which Drives Fit the RC8?

    Fitment is set by the hub, not the machine. The RC8 has a 2.5 inch hex hub, which matches the output shaft on Digga 9DDS through 12DDS drives. A 3 inch hex hub is available if your drive uses that shaft. Where a drive and bit do not match, auger adapters convert between hub sizes, and auger extensions add depth below the bit. On this page the hub option reads 3" Hex Hub.

    Where the RC8 Sits Against Digga's Other Bits

    • The RC8 is the all-rounder — taper teeth cut a clean hole in soft ground and rip fracturable rock, so one bit covers what would otherwise need two.
    • An earth bit costs less (A8) and cuts just as well if you only ever drill soil.
    • A dedicated rock auger (DR11) is the better tool where the ground is hard rock rather than mixed.

    On delivery: check the bit before you sign, and note any damage on the delivery receipt at the time of delivery. Photograph anything that looks wrong and email support@eskidsteer.com.

    Digga RC8 Auger Bit Questions, Answered

    What size RC8 do I need?

    Match the diameter to the hole, not to the drive — then check the drive can turn it. Digga rates each drive to a maximum diameter in earth and a smaller one in clay or shale, and those figures are on the drive listings. The RC8 is offered in fourteen diameters from 8 to 60 inches.

    Why choose the RC8 over an earth bit?

    Taper teeth cut a clean hole in soft ground and still rip fracturable rock, so one bit covers conditions that would otherwise need two. If you only ever drill soil, an earth bit costs less and cuts just as well.

    Will the RC8 fit my auger drive?

    If your drive has a 2.5 inch hex output shaft, yes — that covers Digga 9DDS through 12DDS. For a different shaft, auger adapters step between hub sizes, though an adapter adds length and a joint, so a matched hub is better where you have the choice.

    Are teeth and pilot included?

    Yes. Every Digga bit ships with pin, clip, teeth and pilot fitted. Teeth and pilots are wear parts, so they are also sold separately — for this bit, the ttd tungsten taper teeth and the PH-3, or PH-3XL above 30 inches.

    How deep can I drill?

    The RC8 is 60 in overall, and the drive adds its own length above it. To go deeper, auger extensions fit between the drive and the bit. Two shorter extensions are usually more practical than one long one, because the whole stack has to be lifted clear of the hole.

    When do teeth need changing?

    When the cutting edge has worn back and the bit slows or starts wandering. Replacing teeth is far cheaper than wearing into the pockets or the flights, which are the expensive parts of the bit.
