📘 Overview
The Blue Diamond Fixed Auger Extension adds a set length of reach to your skid steer auger drive, letting you drill deeper without changing to a longer auger. It installs on a standard skid steer auger drive quick-attach shaft. It installs between the auger drive and the bit and delivers a rigid, fixed working length for consistent depth on repetitive drilling. It is a dependable blue diamond auger extension for professional operators.
This listing covers the fixed extension range in 2″ hex and 2 9/16″ round shaft interfaces, in lengths from 12″ to 72″. Match the shaft to your auger drive's output and choose the length for the depth you drill most.
As an auger extension skid steer operators rely on for consistent depth, the fixed design is simpler and more rigid than a variable extension — ideal when you drill to the same depth repeatedly. A drill depth extension auger like this keeps a standard drive working on deep holes, and a 6 foot auger extension hex shaft (the 72″ model) reaches well below frost line for posts and footings.
Each extension ships as a kit with a retainer bolt. Common uses include fence and sign posts, deck and deep footings, and any drilling that needs more depth than the auger alone provides.
⚙ Fixed Auger Extension Features
- Fixed working length for consistent, repeatable depth
- Available in 2″ hex and 2 9/16″ round shaft interfaces
- Lengths from 12″ to 72″
- Rigid one-piece design
- Ships as a kit with retainer bolt
- Fits between auger drive and auger bit
🔑 Why Choose the Blue Diamond Fixed Auger Extension
- Consistent depth on repetitive work — a fixed length means every hole reaches the same depth without adjustment, ideal for production post-setting.
- More rigid than a variable extension — the one-piece design has no adjustment joint, so it's stiffer for straight, true holes.
- Reach depth without a longer auger — extend your existing bit rather than buying a full-length auger, saving cost and storage space.
- Matches your drive's shaft — 2″ hex and 2 9/16″ round options pair with standard auger drive output shafts.
- Complete kit with retainer bolt — ready to install between drive and bit out of the box.

❓ Frequently Asked Questions
Q: Fixed or variable extension — which do I need?
Choose fixed if you drill to the same depth repeatedly and want a rigid, simple extension. Choose variable if you drill a range of depths and want to adjust length on the fly. Fixed is stiffer and typically less expensive for a given length.
Q: Which shaft size should I order?
Match it to your auger drive's output shaft and bit input — either 2″ hex or 2 9/16″ round. Order the extension that matches your drive output; if your bit differs, you may need a matching bit for the extension's lower end.
Q: What length do I need?
Lengths run 12″ to 72″. Add the extension length to your auger's drilling depth for total reach. For frost-line posts, the 72″ (6-foot) hex-shaft model reaches deep; shorter extensions handle modest depth increases.
Q: Is the retainer bolt included?
Yes — each fixed extension ships as a kit with the retainer bolt, ready to install between your drive and bit.
Q: How is shipping calculated?
Shipping is calculated at checkout — add the item to your cart, enter your delivery address, and the shipping charge is displayed before you complete your order. Lift gate service is available for residential deliveries and can be selected at checkout.
