This comprehensive flat wood drill bit set delivers reliable performance across a wide range of wood drilling applications. Crafted from durable high carbon steel, each of the six bits measures 150mm in length with a convenient quarter-inch hex shank for swift tool changes. The set includes sizes 10, 12, 16, 18, 20, and 25mm, making it versatile for softwood, hardwood, and plasterboard projects. The quick-change shank design works seamlessly with most standard adaptors, helping you switch between tasks efficiently. While these bits excel at boring clean holes in wood and board materials, they're not designed for laminate work.
