📘 Overview
Star Industries Heavy Duty Skid Steer Auger Shaft Extensions add drilling depth to any 2"" hex shaft auger without requiring a new bit. Available in 24"" (160A-E24), 36"" (160A-E36), 48"" (160A-E48), 60"" (160A-E60), and 72"" (160A-E72) lengths. The 2"" hex coupler connects between the drive unit and auger bit, extending the shaft by the selected length. Built from high-grade American materials to handle the same torsional loads as the auger bit itself. 5-year factory guarantee. USA made since 1981.
⚙️ Key Features
- Available lengths: 24"", 36"", 48"", 60"", 72""
- 2"" hex coupler interface — compatible with all Star Industries and standard 2"" hex auger drives
- High-grade American steel construction
- Extends drilling depth without a new bit
- Multiple extensions can be stacked for additional depth
- 5-year factory guarantee | USA made since 1981
🔑 Benefits
- Adds drilling depth for footings, piers, and deep fence posts without purchasing a new bit — many drilling applications require more depth than the standard 48"" auger bit provides. An extension adds the required depth at a fraction of the cost of a new auger bit, and the extension works with any bit in your existing inventory.
- Multiple extensions can be stacked for maximum depth applications — pier drilling, caisson work, and deep utility pole installations may require 8'–12' of total drilling depth. Stacking a 48"" and 36"" extension, for example, adds 7' of depth to a standard bit without any specialized equipment.
- 2"" hex standard allows cross-compatibility with non-Star drives and bits — the 2"" hex coupler is the industry standard for skid steer auger drives. Star extensions work with any auger drive using the 2"" hex interface, not just Star units, making them interchangeable across mixed-brand auger fleets.
- American high-grade steel ensures the extension is not the torsional weak point in the auger stack — an extension shaft must handle the same peak torsional loads as the auger bit itself when the bit stalls in hard material. Undersized or low-grade extension shafts are the most common point of torsional failure in extended auger configurations. Star's high-grade steel matches the torsional strength of the auger bit shaft.

🔗 Attachment Compatibility
Compatible with Star Industries 160D series auger drives and all auger drives with a standard 2"" hex output shaft. Confirm your drive unit and auger bit both use the 2"" hex interface before ordering. When stacking extensions, total shaft length affects auger stability — consult Star Industries for guidance on maximum recommended extension depth for your drive unit and bit combination.
🚜 Machine Compatibility
Compatible with skid steer loaders and compact track loaders with a Universal Quick Attach (SSQA) system:
| Bobcat | Caterpillar | John Deere | Case |
| New Holland | Takeuchi | Kubota | Gehl |
Compatibility determined by mount type — confirm your machine's quick attach configuration before ordering.
❓ FAQs
|
Q: Can I use multiple extensions to get greater depth?
Yes — extensions can be stacked between the drive unit and auger bit to achieve additional depth beyond what a single extension provides. For example, a 48"" extension + 36"" extension adds 84"" (7') of depth. Note that longer total shaft lengths can reduce drilling torque efficiency and increase side-load risk — contact eSkidSteer at 866-757-8337 for guidance on maximum stacking depth for your specific drive unit. |
|
Q: What coupler size do I need?
These extensions use the 2"" hex coupler, which is the industry standard for skid steer auger drives. Verify your drive unit's output shaft is 2"" hex before ordering. Mini skid steer drives and backhoe-mount drives may use different shaft sizes — confirm before purchasing. |
|
Q: Does extension length affect torque output?
Each additional extension adds a small amount of transmission loss due to coupler engagement and shaft flex. For most applications the difference is negligible. In hard material drilling at maximum depth, longer extensions can reduce effective torque at the bit — the 160D-1020M (10-20 GPM, higher torque) is recommended for deep-extension applications in tough soil. |
|
Q: Can these extensions be used with non-Star auger bits and drives?
Yes — the 2"" hex coupler interface is an industry standard used across most skid steer auger manufacturers. Star Industries extensions will work with any drive and bit using the 2"" hex interface, regardless of brand. Confirm the 2"" hex interface on both the drive and bit before combining. |
|
Q: What is the weight of each extension?
Exact weights by model are not published by Star Industries. As a reference, a third-party 48"" 2"" hex extension typically weighs approximately 50-60 lbs. Contact eSkidSteer at 866-757-8337 for weight specifications by model. |
