Can you use a Forstner bit in a hand drill? Or a drill press? They are generally made of high-speed steel or carbide and are sharpened using a bench grinder or other sharpening tool. They can also be used to create decorative inlays and to drill partially through a piece of wood to create a stopped hole.įorstner bits are typically used with a drill press, but can also be used with a hand-held drill if care is taken to keep the bit straight and to apply a steady, even pressure. This design allows them to cut a clean, flat-bottomed hole with little or no tear-out on the back side of the workpiece.įorstner bits are available in a range of sizes and are typically used in woodworking and carpentry to create holes for dowels, screws, and other fasteners, as well as to create mortises and other joinery. Unlike twist drill bits, which have a point that cuts into the material and a helical flute that removes the chips, Forstner bits have a flat end and a series of small, flat cutting edges around the circumference of the bit.
