Forstner bits are precision drilling tools designed to create smooth, flat-bottomed holes in wood. Featuring a unique rim-guided design with sharp cutting edges, these bits produce clean, tear-free holes with minimal splintering. The center spur ensures accurate positioning, while the radial cutting edges allow the bit to cut at an angle or even overlap existing holes without drifting. Constructed from high-quality steel, Forstner bits are ideal for tasks requiring precise hole placement, such as cabinetry, furniture making, and doweling.. All bits have a 3-1/2″ overall length and a 3/8″ shank
