Auger Tooth Rock Ripper RL08 | Pengo Attachments By Paladin

Overview

These Pengo rock auger teeth — the S-RL08 standard rock tooth, stocked as PG-990021 — are the conical teeth supplied as standard on the Pengo Severe Rock Ripper auger. Each weighs 0.7 lb and carries Pengo soil rating 5 and 6, gravel and fracturable rock. They mount into the auger head rather than to the machine quick attach, so fitment follows the Severe Rock Ripper head itself.

Key Features of the Pengo S-RL08 Rock Auger Teeth

• Standard tooth on the Severe Rock Ripper auger — the tooth Pengo ships the SRR with.
• Conical rock tooth design for hard rock applications, rated 5–6 on the Pengo soil chart.
• 0.7 lb per tooth, a genuine Pengo part ordered by part number.
• Upgrade path published by Pengo: replace with SR-76SW Strata carbide teeth for increased performance and life-cycle.
• Removed with the C123 puller, so a worn set changes on site.
• Seats in a P-10 pocket (0.86" shank pocket), the holder Pengo specifies for this tooth.
• A conical rock auger tooth, not a dirt tooth — these are severe rock ripper teeth built for material that destroys standard auger rock teeth.
• Genuine Pengo auger teeth ordered by part number, so shank and pocket fit are correct.

Why the Standard Rock Tooth Is Often the Right Buy

• It is what the auger was built around. Pengo supplies the Severe Rock Ripper with S-RL08 teeth as standard, so this is the baseline the auger is designed for.
• Rated for the ground the SRR works in. Soil 5–6 covers gravel and fracturable rock, which is the whole point of a rock ripper auger.
• Cheaper per tooth than Strata carbide. Where abrasion is moderate, standard teeth are the economical choice and the upgrade is there when it is not.
• Field-replaceable. The C123 puller removes them without damaging the head, so a tooth change does not mean a trip to the workshop.
• Hard rock auger teeth priced as a consumable. Buying rock teeth for auger work by the set is far cheaper than letting a worn set damage the head.

Pengo S-RL08 Rock Tooth Specifications

Standard S-RL08 or Strata SR-76SW?

Pengo publishes the choice plainly: the Severe Rock Ripper comes standard with S-RL08 conical teeth, and you replace with SR-76SW Strata conical teeth for increased performance and life-cycle. Both weigh 0.7 lb and both are rated 5–6. The difference is drilling-grade carbide in the Strata tooth, which buys life in abrasive rock at a higher price per tooth. One practical consequence worth knowing before you switch: the Strata tooth has an enlarged shoulder and needs the C30 puller to remove, where the standard S-RL08 uses the C123 puller.

What These Teeth Fit

The S-RL08 seats in a P-10 pocket on the Pengo Severe Rock Ripper auger head, which mounts through a Pengo auger drive to a skid steer, mini excavator or backhoe quick attach. The tooth fits the auger, not the machine, so the loader behind it does not affect fitment.
