When a standard length bit just won’t reach, these 460mm long auger bits wood workers and site carpenters have relied on for decades are exactly what the job needs. Whether you’re drilling through thick timber frames, running cable routes through joists, or boring holes in deep sections of engineered board, the extra length gives you the reach without having to resort to extensions or awkward workarounds.
The cutting edges are ground and sharpened to a precise profile, giving a clean entry and a controlled exit hole. That matters more than people sometimes think. A ragged exit on a stud wall or a joist means more filling, more finishing, and more time. The specialist screw-in point pulls the bit forward as it cuts, which reduces the effort needed and keeps the hole on track through the material.
Where Long Auger Bits for Wood Are Used
These bits are suitable across hardwood and softwood, and they handle the engineered boards that make up most modern builds just as well. Plywood, MDF, chipboard and particle board all cut cleanly. The hexagon shank is a practical feature that often gets overlooked until you’ve had a round shank spin in a chuck at the wrong moment. Here it locks positively into most standard rotary drills and bracers, so the bit drives the cut rather than just spinning hopefully.
Size Range
Available in ten diameters from 8mm through to 32mm, so you can match the bit to the cable, pipe, or fitting you’re working around. Buying the right size first time is significantly less annoying than trying to open out an undersized hole halfway through a joist.
At 460mm, these long auger bits give genuine reach without sacrificing control. Solid working bits for everyday site use.
Pro Tip: When drilling through multiple joists in a run, keep the drill speed moderate and let the screw point do the pulling work rather than forcing the bit, this keeps the hole centred and reduces the chance of the bit wandering off-line mid-timber.
These 460mm auger bits are used wherever a standard length bit falls short. Structural timber frames, floor joists, roof trusses and partition studs are the obvious applications, particularly when running cable or pipe through a series of members. Joinery work on thick hardwood sections and laminated timber beams also benefits from the extra reach. On renovation jobs, where access is limited and you need to drill through from one face without repositioning, the length earns its keep quickly.

Key Specifications
Overall length: 460mm
Sizes available: 8mm to 32mm
Hexagon shank for positive chuck grip
Specialist screw-in point for self-pulling action
Ground and sharpened cutting edges
Not suitable for: Not suitable for drilling into masonry, metal or composite materials. Not designed for use with impact drivers.
Fit the hexagon shank into your drill chuck and tighten securely. Mark your drilling position, start at a low speed to let the screw point bite, then increase speed once the bit is seated. Keep the drill as square to the surface as you can, particularly on through-holes where exit position matters. Withdraw the bit periodically on deeper bores to clear waste and reduce heat build-up.
Select the correct diameter bit for your cable, pipe or fixing requirement
Insert the hexagon shank into the drill chuck and tighten fully
Mark the drilling position and check for obstructions on the opposite face if drilling through
Start at low speed to allow the screw point to pull into the material
Increase speed once the bit is established in the wood
Withdraw the bit periodically to clear shavings and prevent clogging
Reduce speed as the bit approaches the exit face to control breakout
Will these auger bits fit a standard cordless drill?
Yes, the hexagon shank fits most standard rotary drill chucks, including cordless drills and corded drills with a keyless or keyed chuck. They are also compatible with traditional bracers. They are not suitable for use in impact drivers.
Can these bits be used on MDF and chipboard as well as solid wood?
Yes. They are suitable for MDF, chipboard and particle board as well as hardwood, softwood and plywood. The ground cutting edges handle engineered boards cleanly without excessive tearing.
What is the benefit of the screw-in point over a standard flat point?
The screw-in point pulls the bit forward into the material as it rotates, which reduces the pressure you need to apply and helps keep the bit tracking straight. It also tends to produce a cleaner entry hole than a plain flat tip.
Manufactured with precision-ground and sharpened cutting edges for consistent bore quality across softwood, hardwood and engineered sheet materials. The self-feeding screw-in tip reduces feed pressure and improves hole accuracy over the full 460mm working length. The hexagonal shank profile provides a positive, slip-resistant connection in standard drill chucks and bracers.
