Auger Bit 4pc Set – 600mm Extra Long – Hex Shank

When a standard auger bit falls short, literally, these long auger bits are what you reach for. This four-piece set gives you 600mm of working length across four essential sizes: 8mm, 12mm, 16mm and 24mm. The hex shank keeps each bit locked into your drill or brace without slipping, which matters when you’re driving hard through thick structural timber and the torque builds up.

Carpenters, electricians and plumbers all end up needing to drill through wall plates, joists or stud work at some point. The 600mm length means you can get through doubled-up framing or thick floor sections in one pass, rather than drilling from both sides and hoping the two holes meet somewhere in the middle. Anyone who has tried that particular trick knows how it usually ends.

Where These Long Auger Bits Get Used

The auger design pulls the bit through timber rather than relying purely on downward pressure. That screw point draws you in cleanly, and the spiral flute clears waste efficiently so the bit doesn’t bind or burn. It’s a proper mechanical advantage that makes deep drilling considerably less effort than using a standard twist or spade bit at this depth.

The hex shank fits standard quick-change chucks and brace-style adapters, so these slots into whatever you’re already using on site. No adapters needed, no faffing about. The four sizes in this set cover the most common cable, pipe and bolt hole requirements you’ll encounter in timber frame work, so there’s a reasonable chance you’ll use all four of them.

At this length and price, it’s a sensible set to keep in the bag for the jobs where nothing shorter will do.
