Carbide Triflow Auger Bit Pilot Tooth | Pengo Attachments By Paladin

Overview

This Pengo carbide auger pilot bit — the Carbide Triflow Auger Bit Pilot Tooth (TF-350CXC, part number 135091) — is the pilot that leads a Pengo auger into the ground. It weighs 5.8 lb and carries Pengo soil rating 2 – 3 – 4 – 5, suiting sand, silt, clay and gravel. Like every TriFlow 350 pilot it uses three drill points rather than one, which is what gives the family its wear life and keeps the auger tracking straight from the first turn. It mounts into the auger head itself, so fitment follows the Pengo Aggressor or TriMax head rather than the machine quick attach behind it.

Key Features of the Pengo Carbide Triflow Auger Bit Pilot Tooth

• Widest soil range in the family — rated 2-3-4-5, from sand through gravel.
• Heaviest grade at 5.8 lb, reflecting the additional carbide.
• Pengo triflow carbide pilot, part 135091 — note this is a different grade from the TF-350C carbide tipped pilot bit, which is rated 4-5.
• Listed by some suppliers as auger tips carbide; the Pengo part number is what identifies it unambiguously.
• Pengo soil rating 2 – 3 – 4 – 5 — sand, silt, clay and gravel, so the grade is matched to ground rather than guessed.
• TriFlow 350 three-point design — three drill points spread the work and extend service life against a single-point pilot.
• 5.8 lb, a direct replacement TF-350CXC pilot bit for Pengo Aggressor and TriMax augers.
• Genuine Pengo part, ordered by Pengo part number rather than an aftermarket equivalent — the same catalogue that lists Pengo auger teeth and holders.
• A triflow pilot bit is the centre of the cutting set, working with the auger bit teeth around the head rather than replacing them.

Why the Right Carbide Auger Pilot Bit Matters

• The pilot goes in first. It sets the hole centre and pulls the auger down — a worn or wrong-grade pilot makes the whole auger work harder.
• Three drill points, not one. The TriFlow design spreads wear across three cutting points, which is why the family lasts longer than a conventional pilot bit.
• Grade matched to ground. Running a standard pilot in gravel wastes it quickly; running carbide in soft dirt spends money on wear resistance you never use.
• Replacing the pilot is cheaper than replacing the auger. The pilot is the consumable that protects the head behind it.
• One pilot bit for auger work across the season. Because grades share fitment, changing ground means changing the pilot rather than the whole cutting set.

Which TriFlow 350 Pilot Grade Do You Need?

Pengo builds the TriFlow 350 pilot in five grades. They share the same three-point design and the same fitment — the difference is the ground each is rated for, and how much wear protection you are paying for.

Grade Pengo model Part number Weight Soil rating Best in Standard TF-350 135088 5 lb 1 – 2 – 3 Dirt, sand, silt Hardface TF-350HF 135089 5.5 lb 2 – 3 – 4 Sand, silt, clay Hardface carbide TF-350HFTC 135092 5.5 lb 2 – 3 – 4 Sand, silt, clay — abrasive Carbide TF-350CXC 135091 5.8 lb 2 – 3 – 4 – 5 Sand through gravel — widest range Carbide tipped TF-350C 135090 5.5 lb 4 – 5 Clay, gravel

The TF-350C carbide tipped pilot focuses on clay and gravel at rating 4-5, while the TF-350HFTC hardface carbide pilot and TF-350HF hardface pilot cover 2-3-4. For soft ground the standard TF-350 is the economical choice.

Which Augers Fit This TriFlow Pilot?

The TriFlow 350 pilot fits Pengo Aggressor and TriMax augers, which mount to skid steer loaders, mini excavators and backhoes through a Pengo auger drive. The pilot threads into the auger head, so fitment is decided by the auger, not by the machine driving it.
