Auger Bits – 230mm Long

Auger bits are the go-to choice when you need a clean, accurate hole through timber rather than just forcing your way through it. These 230mm versions give you enough length to work through structural timbers, door frames and thick sheet materials without needing an extension, which saves time on most standard joinery and installation jobs. The screw-in point pulls the bit forward as you drill, reducing the pressure you need to apply and giving you a cleaner entry and exit hole than you would get from a standard twist bit.

The cutting edges are ground and sharpened to a proper geometry, not just pressed into shape. That matters more than it sounds. A poorly ground auger bit wanders, burns, and leaves a rough hole that makes fitting plugs, dowels or cable runs harder than it needs to be. These are designed to cut efficiently across hardwood, softwood, plywood, MDF and chipboard, so you are not swapping bits every time the material changes.

Where These Auger Bits Earn Their Keep

The hexagon shank is a practical detail worth mentioning. Most rotary drills and braces will grip a hex shank without slipping under load, which is exactly what you want when you are drilling at an angle into a joist or working one-handed above your head. It is a small thing until the bit spins in the chuck at the wrong moment.

The 230mm length suits cable and pipe installers, carpenters, kitchen fitters and general builders who regularly need to pass services through timber. Sizes run from 6mm right up to 32mm, so whether you are threading a cable or boring out a 32mm hole for a pipe sleeve, there is a bit in the range that fits the job. Sold individually, so you can buy exactly what you need rather than paying for a set full of sizes you will never use.
