⚡ At a Glance
- • Reach & Compatibility: Auger bit extension shaft that enables access to deep or concealed cavities and fits with common auger setups
- • Best for: Tradespeople and DIY enthusiasts who need to drill through false floors, deep post holes and awkward spaces
- • Not ideal for: Jobs requiring quick-release tool changes or non-standard auger systems that need bespoke adaptors
Lacquered auger extension shaft supplied with two locking screws and a hexagonal key. Designed to accept standard auger attachments and resist surface corrosion.
Extended reach for awkward drilling – with an auger bit extension shaft
The shaft acts as an inline extension between the drill and standard auger bits, increasing reach without altering the cutting head. Secure connections minimise play where the extension meets the auger and the drill chuck.
Accesses deep or concealed cavities such as false floors and post footings, reducing the need for awkward body positions or makeshift extensions.
Reduced corrosion risk – thanks to a lacquered finish
A factory-applied lacquer coating forms a barrier against moisture and site grime, slowing surface oxidation. The finish lowers the frequency of surface maintenance compared with uncoated steel.
Remains serviceable longer on damp building sites, cutting downtime for cleaning and rust treatment.
Secure connections under load – with two locking screws and supplied hex key
Twin locking screws clamp the shaft-to-shank interface, while the included hexagonal key allows correct torque to be applied. The arrangement reduces slippage and keeps the alignment steady during heavy drilling.
Delivers stable drilling with less wobble, helping to produce cleaner, more accurate holes and reducing the chance of work interruptions.
