RC4 Inner Auger Tooth - Digga

📘 Overview

The Digga TTS-3 is the MFT taper inner tooth for Digga RC4-RC10 Rock/Combination Auger Bits — designed for general-purpose and all-conditions drilling. The TTS-3 uses the TTD-H taper tooth pocket and sits in the inner positions of the RC auger head, working alongside TTD-3 outer teeth to provide complete coverage. The taper tooth system uses a 1-step knock-in/knock-out process for fast field replacement without special tools. For machines up to 50 tons. OEM Digga, made in Dyersville, Iowa, USA.

⚙️ Key Features

• Part No. TTS-3 — MFT taper inner tooth for Digga RC4 through RC10 auger bits
• TTD-H taper pocket
• Multi-facet tungsten (MFT) tip — all-conditions: earth to medium rock
• Inner tooth position on RC auger head
• 1-step knock-in/knock-out — taper lock, tool-free field replacement
• General purpose — earth, clay, shale, asphalt, soft-medium rock
• For machines up to 50T | OEM Digga | Made in Dyersville, Iowa, USA

🔑 Benefits

• Taper tooth design provides higher impact retention than flat-base tooth systems in hard rock — the taper lock engages deeper into the pocket under drilling load, creating a self-locking effect that resists the high vibration of rock contact. This prevents tooth loss in demanding conditions where flat-base teeth (TS system) would risk ejection.
• MFT geometry on TTS-3 inner teeth fractures center-zone hard material the RC4 outer teeth cannot reach — the inner tooth position engages the core of the hole where rotational speed is lowest and harder material must be fractured by force rather than by speed. MFT geometry concentrates this force effectively at center.
• 1-step knock-in/knock-out eliminates field tooth change complications on rock jobs — on rock drilling jobs where tooth replacement is frequent, the taper system's single-step removal and installation (no special tools) keeps the drill crew working. A full tooth set can be changed in under 15 minutes in the field.
• RC4-RC10 compatibility means TTS-3 inner teeth cover the full RC series range from skid steer to large excavator — the same TTS-3 inner tooth serves all machine classes in the RC range. Operators running multiple RC series bits across different machine classes only need to stock one inner tooth part number.

📊 Specifications

🔗 Attachment Compatibility

For Digga RC4 through RC10 Rock/Combination Auger Bits using TTD-H taper pockets. Inner tooth position. Not for A4 (TS system) or DR series (DP system). Pair with TTD-3 outer teeth for complete head service. For RC11, use TTL-3 outer teeth.

🚜 Machine Compatibility

RC4 suits skid steers and excavators up to 4.5T. Larger RC series (RC6-RC10) suit machines to 50T. This inner tooth fits the full RC series:

Machine compatibility inherited from parent RC series auger. RC4 = 0.75T–4.5T. RC6 through RC10 = larger excavator classes up to 50T. Confirm your RC model and machine class.
