Expansive Drill Bit Set 22-76mm Adjustable Wood Boring

An expansive drill bit set for cutting adjustable hole sizes in wood, covering a wide range from 22mm up to 76mm. Supplied as a 2-piece cutter set with a 9mm hex shank and hex key, it is suited to jobs where a standard fixed-size bit would be too limiting.

Used for wood boring when larger holes are needed for fitting pipe runs, cable access, vents or other openings in timber and sheet material. Handy for workshop use, site fitting, joinery tasks and general DIY repairs, especially when you need to change hole size without carrying several separate flat wood bits.

The set includes a small bit covering 22-45mm and a large bit covering 45-76mm, giving broad coverage across common larger boring sizes. A 9mm hex shank helps the bit sit securely in a suitable drill chuck, while the included hex key allows adjustment of the cutter position to the size required. For repeated fitting and maintenance work, the adjustable range helps reduce the need to switch between multiple individual hole cutters and keeps the job more straightforward when different hole diameters are needed on the same job.
