Expansive Bit 15-45mm for Wood - Tork Craft
Expansive auger bit Ø15-45mm
An expansive auger bit has an adjustable cutter, for boring holes of different diameters.
A scale on the cutter blade indicates the diameter of the hole to be bored.
It is a must have for a woodworker who is required to drill an odd size diameter hole.
Drill into an off-cut first to determine if the desired diameter is correct.
Always keep the drill bit perpendicular to the workpiece.
