About this product
This Faithfull flat bit is a 20mm diameter drill bit with an overall length of 152mm, suited to large-scale drilling in timber, such as substantial plumbing work, cable installations and heavy-duty construction. It bores cleanly with or against the grain, thanks to a precision ground point and extended spurs for faster cutting.
Made to DIN 3126 quality standards, it has a 1/4in hexagonal non-slip shaft with a locking mechanism compatible with quick-release chucks or adaptors, and works with both mains and cordless drills. Being impact rated, it is built for durable, professional use, and can be paired with an optional 300mm extension shank for deep drilling applications.
