BulletPoint3 : Feature - Our hexagonal shank single tooth drill bits are designed with beveled alternating blades, which are efficient and durable, and also can drill fine holes, with no burrs. The drill tip adopts a center point positioning design, and the single tooth flat wing design reduces cutting resistance and friction, making drilling easy, fast and accurate. BulletPoint4 : Application - The Forstner hole saw will drill through a multitude of materials. Such as wood, plastic, plywood, solid wood boards, MDF, plastics, furniture, door hinges, desks, etc. It can be used in a drill press, bench drill, vertical drilling machine, CNC carving machine, etc. BulletPoint5 : Note - When drilling with a Forstner drill bit, please control the appropriate speed. Too fast or too slow will not achieve the desired effect and may reduce the service life of the drilling tool.
